This tool does not verify whether modules within a system are compatible, but it does provide the minimum IOS requirements for individual hardware modules or components.

Note Access to this tool is limited to users with Cisco.com login accounts.

To access Software Advisor, click Login at Cisco.com and go to Technical Support Help—Cisco TAC: Tool Index: Software Advisor. You can also access the tool by pointing your browser directly to http://www.cisco.com/go/swadvisor.

Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

Tools and Parts Required

You need the following tools and parts to install or upgrade an FEIP2-DSW. If you need additional equipment, contact a service representative for ordering information.

Number 1 Phillips and a 3/16-inch, flat-blade screwdriver
ESD-prevention equipment or disposable grounding wrist strap included with all Cisco products
FEIP2-DSW-2TX= or FEIP2-DSW-2FX=, and at least one available interface processor slot in your Cisco 7000 series or Cisco 7500 series router (For specific compatibility requirements, refer to the "Software and Hardware Requirements" section.)
Cables appropriate for the FE interfaces on your FEIP2-DSW; Cisco Systems does not supply Category 5 UTP RJ-45 cables, MII cables, or SC-type, 62.5/125-micron optical-fiber cables; these cables are available commercially. (For specific cable requirements, refer to the "FEIP2-DSW Receptacles, Cables, and Pinouts" section.)

Caution Before you attach an MII transceiver to an MII receptacle on your FEIP2-DSW, ensure that your MII transceiver responds to physical sublayer (PHY) address 0 per section 22.2.4.4. "PHY Address" of the IEEE 802.3u specification; otherwise, interface problems might result. Confirm that this capability is available on your MII transceiver with the transceiver's vendor or in the transceiver's documentation. If a selection for "Isolation Mode" is available, we recommend you use this setting (if no mention is made of "PHY addressing").

Caution To prevent system problems, do not simultaneously connect cables to the RJ-45 (or SC) and MII receptacles on a single FEIP2-DSW, FE interface. Each FE interface (100BASE-FX or 100BASE-TX) can have either an MII attachment or an RJ-45 (or SC) attachment, but not both. The MII and RJ-45 (or SC) receptacles represent two physical connection options for one FE interface.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis
Do not work alone when potentially hazardous conditions exist.
Never assume that power has been disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard or makes the equipment unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.

Electrostatic Discharge Prevention

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures.

Use the following guidelines for preventing ESD damage:

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the strap to an unfinished chassis surface.
When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane.
When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
Place a removed component board-side-up on an antistatic surface or in a static shielding container; otherwise, immediately place it in a static shielding container.
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Guidelines for Interface Processor Installation and Removal

This section describes mechanical functions of system components, emphasizes the importance of following correct procedures to avoid unnecessary board failures, and is for background only; specific procedures follow in the "FEIP2-DSW Installation" section. You can remove and replace interface processors while the system is operating; you do not need to notify the software or reset the system power. This functionality enables you to add, remove, or replace interface processors with the system online, which provides a method that is seamless to end users on the network, maintains all routing information, and ensures session preservation.

After an interface processor is reinstalled, the system brings on line only interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command.

Caution The system can indicate a hardware failure if you do not follow proper procedures. Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or inserting another interface processor. Disrupting the sequence before the system completes its verification can cause the system to interpret hardware failures.

Cisco 7000 series and Cisco 7500 series routers have ejector levers located on the ends of the interface processor slots. (See Figure 1a.) The function of the ejector levers is to align and seat the card connectors in the backplane. Failure to use the ejector levers and insert the interface processor properly can disrupt the order in which the pins make contact with the card or interface processor. Follow the FEIP2-DSW installation and removal instructions carefully, and review the following examples of incorrect insertion practices and their results:

Using the handle to force the interface processor all the way into the slot can pop the ejector levers out of their springs. If you then try to use the ejector levers to seat the interface processor, the first layer of pins (which are already mated to the card or interface processor) can disconnect and then remate with the backplane, which the system interprets as a board failure.
Using the handle to force or slam the interface processor all the way into the slot can damage the pins on the board connectors if they are not aligned properly with the backplane.
When using the handle (rather than the ejector levers) to seat the interface processor in the backplane, you might need to pull the interface processor back out and push it in again to align it properly. Even if the backplane pins are not damaged, the pins mating with and disconnecting from the card or interface processor might cause the system to interpret a board failure. Using the ejector levers ensures that the board connector mates with the backplane in one continuous movement.
Using the handle to insert or remove an interface processor, or failing to push the ejector levers fully against the interface processor, can leave some (not all) of the connector pins mated to the card or interface processor, a state which hangs the system. Using the ejector levers and making sure that they are pushed fully into position ensures that all three layers of pins are mated with (or free from) the backplane.

Use the ejector levers when removing an interface processor to ensure that the backplane connector pins disconnect from the interface processor in the sequence expected by the system. Any interface processor that is only partially connected to the backplane can hang the bus. Steps for correctly performing OIR are included with the following procedures for installing and removing the FEIP2-DSW.

Fast Ethernet Overview

The term Ethernet is commonly used for all carrier sense multiple access/collision detection (CSMA/CD), local-area networks (LANs) that generally conform to Ethernet specifications, including Fast Ethernet under IEEE 802.3u.

Note 100BASE-TX is intended for Environment A, and 100BASE-FX is intended for Environment B.

IEEE 802.3u is well suited to applications where a local communication medium must carry sporadic, occasionally heavy traffic at high peak data rates. Stations on a CSMA/CD LAN can access the network at any time. Before sending data, the station listens to the network to see if it is already in use. If it is, the station waits until the network is not in use, then transmits; this is half-duplex operation.

A collision occurs when two stations listen for network traffic, hear none, and transmit very close to simultaneously. When this happens, both transmissions are damaged, and the stations must retransmit. The stations detect the collision and use backoff algorithms to determine when they should retransmit. Both Ethernet and IEEE 802.3u are broadcast networks, which means that all stations see all transmissions. Each station must examine received frames to determine if it is the intended destination and, if it is, to pass the frame to a higher protocol layer for processing.

IEEE 802.3u specifies the following different physical layers for 100BASE-T:

100BASE-TX—100BASE-T, half and full duplex over Category 5 unshielded twisted-pair (UTP), Electronics Industry Association/Telecommunications Industry Association [EIA/TIA]-568-compliant cable
100BASE-FX—100BASE-T, half and full duplex over optical fiber
100BASE-T4—100BASE-T, half and full duplex over Category 3, 4, or 5 UTP or shielded twisted-pair (STP) cabling with four pairs; also called 4T+ or T2, which is 2-pair UTP over Category 3 cable.

Each physical layer protocol has a name that summarizes its characteristics in the format speed/signaling method/segment length, where speed is the LAN speed in megabits per second (Mbps), signaling method is the signaling method used (either baseband or broadband), and segment length is typically the maximum length between stations in hundreds of meters. Therefore, 100BASE-T specifies a 100-Mbps, baseband LAN with maximum network segments of 100 meters (or 400 meters for 100BASE-FX).

IEEE 802.3u 100BASE-T Specifications

This section provides specifications for IEEE 802.3u 100BaseT. Table 1 provides cabling specifications for 100BaseTX Fast Ethernet transmission over UTP and foil twisted-pair (FTP), and 100BaseFX Fast Ethernet over fiber-optic cables. It also summarizes IEEE 802.3u 100BaseTX and 100BaseFX physical characteristics. Also see Figure 1.

Product Description

The FEIP2-DSW is a dual-port, fixed configuration interface processor that provides two, 100-Mbps, IEEE 802.3u Fast Ethernet (FE) interface interfaces and the capability for Distributed Services (DS) and Distributed Switching (DSW). The dynamic random access memory (DRAM) configuration for the FEIP2-DSW is 32 megabytes (MB), and the standard static random access memory (SRAM) configuration is 2 MB.

Note You can upgrade the DRAM to 64 MB.

The FEIP2-DSW is available in the following fixed configurations:

FEIP2-DSW-2TX(=)—FEIP2-DSW with two, 100BASE-TX FE interfaces (See Figure 3.)

Each 100BASE-TX interface on the FEIP2-DSW-2TX has an RJ-45 connector to attach to Category 5 unshielded twisted-pair (UTP) for 100BASE-TX, and an MII connector that permits connection through external transceivers to 62.5/125-micron multimode optical fiber for 100BASE-FX, or to Category 3, 4, and 5 UTP or shielded twisted-pair (STP) for 100BASE-T4 physical media.

Figure 3 Fast Ethernet Interface Processor (FEIP2-DSW-2TX)

FEIP2-DSW-2FX(=)—FEIP2-DSW with two, 100BASE-FX FE interfaces (See Figure 4 .)

Each 100BASE-FX interface on the FEIP2-DSW-2FX has an SC-type fiber-optic connector for 100BASE-FX, and an MII connector that permits connection through external transceivers to 62.5/125-micron multimode optical fiber for 100BASE-FX, or to Category 3, 4, and 5 UTP or shielded twisted-pair (STP) for 100BASE-T4 physical media.

Figure 4 Fast Ethernet Interface Processor (FEIP2-DSW-2FX)

Each FE interface on an FEIP2-DSW can be configured at 100 Mbps, half duplex, for a maximum aggregate bandwidth of 200 Mbps per pair. Each FE interface on an FEIP2-DSW can also be configured at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 400 Mbps per pair. Further, one FE interface can be configured at 100 Mbps, half duplex, while the other FE interface can be configured at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 300 Mbps per pair.

For interface port and cable pinouts, refer to the "FEIP2-DSW Receptacles, Cables, and Pinouts" section. You can install FEIP2-DSW in any available interface processor slot.

Note Each FEIP2-DSW model is a fixed configuration; therefore, individual FE interfaces are not available as spare parts, do not have handles, and are not field replaceable or removable. You must treat the entire FEIP2-DSW assembly as a field-replaceable unit (FRU).

Caution To prevent system problems, we recommend that you not attempt to remove an FEIP2-DSW FE interface and replace it with another type of interface, nor attempt to mix 100BASE-TX and 100BASE-FX FE interfaces on the same FEIP2-DSW.

Note Each of the FEIP2-DSW-2FX's two 100BASE-FX interfaces uses the MII connector like the FEIP2-DSW-2TX, but the FEIP2-DSW-2FX has an SC-type fiber-optic connector in place of the RJ-45 connector. Either the MII LED or the RJ-45 (or FIBER) LED should be on at any one time; never both.

Caution To prevent system problems, do not simultaneously connect cables to the RJ-45 (or SC) and MII receptacles on a single FEIP2-DSW FE interface. Each FE interface (100BASE-FX or 100BASE-TX) can have either an MII attachment or an RJ-45 (or SC) attachment, but not both. The MII and RJ-45 (or SC) receptacles represent two physical connection options for one FE interface.

FEIP2-DSW LEDs

The FEIP2-DSW contains the enabled LED and a bank of three status LEDs for each of the two FE interfaces (located between the two receptacles on each FE interface—see Figure 5). After system initialization, the enabled LED goes on to indicate that the FEIP2-DSW has been enabled for operation.

Figure 5 LEDs on a Fast Ethernet Interface
(Partial Horizontal Faceplate View of FEIP2-DSW-2TX)

The following conditions must be met before the enabled LED goes on:

The FEIP2-DSW is correctly connected and receiving power
The FEIP2-DSW card contains a valid microcode version that has been downloaded successfully
The bus recognizes the FEIP2-DSW.

If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does not go on.

Following are the three status LEDs and an explanation of what each indicates:

MII—On when the MII port is selected as the active port by the controller.
Link—When the RJ-45 or SC port is active, this LED is on when the FE interface is receiving a carrier signal from the network. When the MII port is active, this LED is an indication of network activity, and it flickers on and off proportionally to this activity.
RJ45 (or FIBER on FEIP2-DSW-2FX)—On when the RJ-45 (or FIBER) port is selected as the active port by the controller.

FEIP2-DSW Receptacles, Cables, and Pinouts

The two interface receptacles on each Fast Ethernet interface are a single MII, 40-pin, D-shell type receptacle, and a single RJ-45 receptacle (or SC-type for FEIP2-DSW-2FX optical-fiber connections). (See the FEIP2-DSW-2TX in Figure 6 and the FEIP2-DSW-2FX in Figure 7.)

You can use either one receptacle or the other; only one receptacle can be used at one time. Each connection supports IEEE 802.3u interfaces compliant with the 100BASE-X and 100BASE-T standards. The RJ-45 connection does not require an external transceiver. The MII connection requires an external physical sublayer (PHY) and an external transceiver. Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are available commercially.

Figure 6 Single FEIP2-DSW-2TX Fast Ethernet Interface (Horizontal Faceplate View)

Figure 7 Single FEIP2-DSW-2FX Fast Ethernet Interface (Horizontal Faceplate View)

The RJ-45 connection does not require an external transceiver. The MII connection requires an external physical sublayer (PHY) and an external transceiver. Figure 8 shows the RJ-45 cable connectors. RJ-45 cables are not available from Cisco Systems, but are available from commercial cable vendors. Table 2 lists the pinouts and signals for the RJ-45 connectors.

Figure 8 RJ-45 Connections, Plug and Receptacle (FEIP2-DSW-2TX)

Warning The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.

Table 2 lists the pinouts and signals for the FEIP2-DSW-2TX's RJ-45 connectors.

(FEIP2-DSW-2TX)

Note Referring to the RJ-45 pinout in Table 2, proper common-mode line terminations should be used for the unused Category 5, UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45, 100BASE-TX port circuitry in the FEIP2-DSW-2TX.

Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure 9 and Figure 10 .

Figure 9 Straight-Through Cable Pinout, RJ-45 Connection to a Hub or Repeater (FEIP2-DSW-2TX)

Figure 10 Crossover Cable Pinout, RJ-45 Connections Between Hubs and Repeaters (FEIP2-DSW-2TX)

Figure 11 shows the duplex SC connector (one required for both transmit and receive), and Figure 12 shows the simplex SC connector (two required, one for each transmit and receive) used for 100BASE-FX optical-fiber connections on the FEIP2-DSW-2FX. These 62.5/125-micron, multimode, SC-type, optical-fiber cables are commercially available; they are not available from Cisco Systems.

Figure 11 Duplex SC Connector (FEIP2-DSW-2FX)

Figure 12 Simplex SC Connector (FEIP2-DSW-2FX)

Note The single-mode aperture ports on the FEIP2-DSW-2FX contain Class 1 LEDs that operate at 1300 nanometers (nm).

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

Warning Class 1 LED product.

Depending on the type of media you use between the MII connection on the FE interface and your switch or hub, the network side of your 100BASE-T transceiver should be appropriately equipped with ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 13 shows the pin orientation of the female MII connector on the FE interface.

The MII receptacle (on both the FEIP2-DSW-2FX and FEIP2-DSW-2TX) uses 2-56 screw-type locks, called jackscrews (shown in Figure 13 ), to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews (screws you can tighten with your fingers) that you fasten to the jackscrews on the FEIP2-DSW MII connector. Use the jackscrews to provide strain relief for your MII cable. (The RJ-45 modular plug has strain relief functionality incorporated into the design of its standard plastic connector.) Figure 13 shows the MII female connector.

Table 3 lists the MII connector pinout and signals. MII cables are available commercially; they are not available from Cisco Systems. Table 3 refers to MII cables used between the MII connector on the FEIP2-DSW and an appropriate transceiver. The connection between this transceiver and your network can be Category 3, 4, or 5, 150-ohm UTP or STP, or multimode optical fiber.

FEIP2-DSW Installation

The following sections describe the procedures for removing or installing an FEIP2-DSW in the Cisco 7000 series or Cisco 7500 series routers. The functionality is the same for each router model; therefore, the term the chassis is used except where specific model issues arise.

The online insertion and removal function allows you to install and remove an FEIP2-DSW without first shutting down the system; however, you must follow the instructions carefully. Failure to insert the FEIP2-DSW properly can cause system error messages indicating a board failure. For a complete description of recommended guidelines for interface processor installation and removal, refer to the "Guidelines for Interface Processor Installation and Removal" section.

Each unused interface processor slot must contain an interface processor filler (which is an interface processor carrier without an interface board) to keep dust out of the chassis and to maintain proper air flow through the interface processor compartment. If you are installing a new FEIP2-DSW that is not a replacement, you must first remove the interface processor filler from an unused slot; to do so proceed to the"Removing an Interface Processor or Interface Processor Filler" section. If you are replacing an FEIP2-DSW, proceed to the "Removing an FEIP2-DSW" section.

Note To ensure compliance with EMI approvals by providing a tight EMI-preventive seal for the Cisco 7507 and Cisco 7513 routers, we recommend that you first install interface processors in the interface processor slots closest to the RSP slots, whenever possible, then work out to the interface processor slots furthest from the RSP slots.

Removing an Interface Processor or Interface Processor Filler

If you plan to replace a currently installed interface processor with an FEIP2-DSW, attach an ESD-preventive wrist strap between you and any unpainted chassis surface; interface processor fillers do not require protection from ESD. Select an interface processor slot for the new FEIP2-DSW and remove the interface processor or interface processor filler as follows:

Step 1 Use a screwdriver to loosen the captive installation screws on the interface processor or interface processor filler. (See Figure 1.)

Step 2 Place your thumbs on both ejector levers and simultaneously pull them both outward to release the filler from the backplane connector (in the opposite direction from that shown in Figure 1c).

Step 3 Grasp the handle with one hand and pull the card straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 14.) Keep the carrier parallel to the backplane.

Step 4 Store the interface processor or interface processor filler for future use.

To help prevent dust and contaminants from entering the chassis, do not leave the interface processor slot open. Immediately proceed to the "Installing an FEIP2-DSW" section.

Removing an FEIP2-DSW

You need not shut down the interface or the system power when removing an FEIP2-DSW or interface processor.

Note In Cisco 7507 or Cisco 7513 systems, online insertion and removal of any interface processor in either CyBus might cause the slave RSP2 to reboot with a bus error or a processor memory parity error. The master RSP will recover from this event and issue a "cBus Complex Restart" message. Cisco 7507 and Cisco 7513 systems that are configured with an RSP4 as the system slave are not affected and will not experience this problem.

If you have a Cisco 7507 or a Cisco 7513 with an RSP2 configured as the system slave, we strongly recommend that you use the following procedure to remove and replace an interface processor:

Step 1 Remove the slave RSP2.

Step 2 Wait 15 seconds.

Step 3 Remove and replace the interface processor using the procedures in this publication.

Step 4 Wait 15 seconds.

Step 5 Reinsert the slave RSP2.

If you are replacing a failed FEIP2-DSW, remove the existing board first, then install the new FEIP2-DSW in the same slot. If you are replacing a currently installed interface processor with an FEIP2-DSW, remove the existing board first, then install the new FEIP2-DSW in the same slot.

Figure 14 shows proper handling of an interface processor during installation.

Figure 14 Handling Processor Modules for Installation and Removal
(Horizontal Orientation Shown)

To remove an FEIP2-DSW or interface processor, follow these steps:

Step 1 Attach an ESD-preventive wrist strap between you and any unpainted chassis surface.

Step 2 If you are replacing a failed FEIP2-DSW, disconnect all cables from the FEIP2-DSW ports; however, if you are only moving an FEIP2-DSW to another slot, this step is not necessary.

Step 3 Use a screwdriver to loosen the captive installation screws at both ends of the board. (See Figure 1.)

Caution Always use the ejector levers to remove or install the FEIP2-DSW. Failure to do so can cause erroneous system error messages indicating a board failure.

Step 4 Place your thumbs on the ejector levers and simultaneously pull both of the ejectors outward (in the opposite direction from that show in Figure 1 c) to release the FEIP2-DSW from the backplane connector.

Step 5 Use the board's handle to carefully pull it straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 14 .) Keep the board parallel to the backplane.

Step 6 Place the removed board on an antistatic mat or foam pad, or place it in an antistatic container if you plan to return it to the factory.

Step 7 If the interface processor slot is to remain empty, install a filler (MAS7K-BLANK) to keep dust out of the chassis and to maintain proper air flow inside the chassis. Do not leave the interface processor slot open. Immediately proceed to the "Installing an FEIP2-DSW."

Installing an FEIP2-DSW

The FEIP2-DSW slides into the open interface processor slot and connects directly to the backplane. The interface processors are keyed to guide pins on the backplane, so the FEIP2-DSW can be installed only in an interface processor slot.

Note To ensure compliance with EMI approvals, by providing a tight EMI seal for the Cisco 7507 and Cisco 7513 routers, we recommend that you first install interface processors in the interface processor slots closest to the RSP slots, whenever possible, then work out to the interface processor slots furthest from the RSP slots.

Figure 1 shows the functional details of inserting an interface processor and using the ejector levers. Figure 14 shows proper handling of an interface processor during installation.

Caution Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to complete its discovery and initialization before removing or inserting another interface processor. Disrupting the sequence before the system has completed verification can cause the system to interpret hardware failures.

Follow these steps to install an FEIP2-DSW:

Step 1 Ensure that a console terminal is connected to the console port (on the RSP or RSP7000) and that your console is turned ON.

Step 2 Hold the FEIP2-DSW handle with one hand and place your other hand under the carrier to support the FEIP2-DSW and guide it into the slot. (See Figure 14 .) Avoid touching the card or any connector pins.

Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only.

Note The processor modules are oriented horizontally in the Cisco 7010 and Cisco 7505 and vertically in the Cisco 7000, Cisco 7507, and the Cisco 7513.

Step 3 Place the back of the FEIP2-DSW in the slot and align the notch on the carrier with the groove in the slot. (See Figure 1.)

Step 4 While keeping the FEIP2-DSW parallel to the backplane, carefully slide it into the slot until the back of the faceplate makes contact with the ejector levers, then stop. (See Figure 1 b.)

Caution Always use the ejector levers when installing or removing processor modules. A module that is partially seated in the backplane might cause the system to hang and subsequently crash, and shoving or slamming the interface processor into the slot can damage the backplane pins and board.

Step 5 Using your thumbs, simultaneously push both ejector levers inward until the FEIP2-DSW is pushed entirely into its slot. (See Figure 1 c.)

Step 6 Tighten both of the captive installation screws.

Caution To ensure proper electromagnetic interference (EMI) isolation for the chassis, make certain to tighten the captive installation screws on each FEIP2-DSW immediately after you install it and before proceeding with the installation of each remaining FEIP2-DSW or other interface processor.

Attaching Cables to FEIP2-DSW

The MII and RJ-45 (or SC) receptacles represent two physical connection options for one FE interface. Each FEIP2-DSW has two FE interfaces. On a single FE interface, you can use either the RJ-45 (or SC for FEIP2-DSW-2FX) connection or the MII connection. You can use the RJ-45 (or SC for FEIP2-DSW-2FX) connection on one FE interface and the MII connection on the other.

Note RJ-45, SC, and MII cables are not available from Cisco Systems; they are available from outside commercial cable vendors.

Connect RJ-45, SC (FEIP2-DSW-2FX), or MII cables as follows:

Step 1 If you have MII connections, attach an MII cable directly to the MII port on the FEIP2-DSW or attach a 100BASE-T transceiver, with the media appropriate to your application, to the MII port on the FEIP2-DSW. (See Figure 15 for FEIP2-DSW-2TX or Figure 16 for FEIP2-DSW-2FX.)

If you have RJ-45 connections, attach the Category 5 UTP cable directly to one of the RJ-45 ports on the FEIP2-DSW. (See Figure 15 for FEIP2-DSW-2TX or Figure 16 for FEIP2-DSW-2FX.) The FEIP2-DSW is an end station device and not a repeater. You must connect the FE interface to a repeater or hub.

If you have an SC connection (FEIP2-DSW-2FX), attach a cable directly to the SC port on one of the FEIP2-DSW-2FX's interfaces. (See Figure 16 .) Use either one duplex SC connector, or two simplex SC connectors, and observe the correct relationship between the receive (RX) and transmit (TX) ports on the FEIP2-DSW-2FX and your repeater.

Figure 15 Connecting MII or RJ-45 Cables (FEIP2-DSW-2TX Shown, Horizontal Orientation)

Note Each Fast Ethernet interface (100BASE-FX or 100BASE-TX) can have either an MII attachment or an RJ-45 (or SC) attachment, but not both. The MII and RJ-45 (or SC) receptacles represent two physical connection options for one FE interface.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

Warning Class 1 LED product.

Figure 16 Connecting MII or SC Cables (FEIP2-DSW-2FX Shown, Horizontal Orientation)

Step 2 For the 100BASE-TX RJ-45 connections, attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 17 .

Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the 100BASE-TX-equipped system and is a required component for proper system operation.

Figure 17 Attaching the Ferrite Bead around the RJ-45 Cable

Caution To prevent problems on your FEIP2-DSW and network, do not simultaneously connect RJ-45 (or SC) and MII cables to one FE interface. On a single FE interface, only one network connection can be used at one time. Only connect cables that comply with EIA/TIA-568 standards. (Refer to Table 1 for cable recommendations and specifications.)

Step 3 Attach the network end of your RJ-45 (or SC) or MII cable to your 100BASE-T transceiver, switch, hub, repeater, DTE, or other external 100BASE-T equipment.

Step 4 Repeat Steps 1 through 3 for the second FE interface as required.

This completes the FEIP2-DSW cable installation.

Using LEDs to Check FEIP2-DSW Status

The FEIP2-DSW has four status LEDs on its faceplate that indicate status on each FE port. (See Figure 18 .)

Figure 18 LEDs (Partial Faceplate View of FEIP2-DSW-2TX)

After you connect cables, observe the LED states and the console display as the router initializes. When the system has reinitialized all interfaces, the enabled LED on the FEIP2-DSW should go on. (For complete descriptions of the FEIP2-DSW LEDs, refer to the "FEIP2-DSW LEDs" section.)

The console screen will also display a message as the system discovers each interface during its reinitialization. After system initialization, the enabled LED goes on to indicate that the FEIP2-DSW is enabled for operation.

The following conditions must be met before the FEIP2-DSW is enabled:

The interface processor is correctly connected to the backplane and receiving power.
The system bus recognizes the interface processor.
A valid version of microcode is loaded and running.

If any of these conditions is not met, the enabled LED does not go on.

Verify that the FEIP2-DSW is connected correctly as follows:

Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the FEIP2-DSW. The system should recognize the FEIP2-DSW interfaces but leaves them configured as down.

Step 2 When the reinitialization is complete, verify that the enabled LED on each FEIP2-DSW FE interface is on and remains on. If the LED does stay on, proceed to Step 5. If the enabled LED does not stay on, proceed to the next step.

Step 3 If an enabled LED fails to go on, suspect the that the FEIP2-DSW board connector is not fully seated in the backplane. Loosen the captive installation screws, then firmly push the top ejector down while pushing the bottom ejector up until both are parallel to the FEIP2-DSW faceplate. Tighten the captive installation screws. After the system reinitializes the interfaces, the enabled LED on the FEIP2-DSW should go on. If the enabled LED goes on, proceed to Step 5. If the enabled LED does not go on, proceed to the next step.

Step 4 If an enabled LED still fails to go on, remove the FEIP2-DSW and try installing it in another available interface processor slot.

If the enabled LED goes on when the FEIP2-DSW is installed in the new slot, suspect a failed backplane port in the original interface processor slot.

If the enabled LED still fails to go on, but other LEDs on the FEIP2-DSW go on to indicate activity, proceed to Step 5 to resume the installation checkout and suspect that the enabled LED on the FEIP2-DSW has failed.

If no LEDs on the FEIP2-DSW go on, suspect that the FEIP2-DSW is faulty.

If the enabled LED still does not go on, do not proceed with the installation. Contact a service representative to report the faulty equipment and obtain further instructions.

Step 5 Use the show interfaces or show controllers cbus command to verify the status of the FEIP2-DSW interfaces. (If the interfaces are not configured, you must configure them using the procedures in the "Configuring the FEIP2-DSW" section.")

If an error message displays on the console terminal, refer to the appropriate reference publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.

Configuring the FEIP2-DSW

If you installed a newFEIP2-DSW or if you want to change the configuration of an existing FE interface, you must enter configuration mode using the configuration command. If you replaced an interface that was previously configured, the system recognizes the new interface and bring it up in its existing configuration.

After you verify that the new FE interface is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you need, such as the following:

Protocols you plan to route on each new interface
Internet protocol (IP) addresses if you plan to configure the interfaces for IP routing
Whether the new interfaces will use bridging

For a summary of the configuration options available and instructions for configuring the FE interfaces on the FEIP2-DSW, refer to the appropriate configuration publications listed in the "If You Need More Information" section.

The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.

Note Each FE interface on an FEIP2-DSW can be configured at 100 Mbps, half duplex, for a maximum aggregate bandwidth of 200 Mbps per pair. Each FE interface on an FEIP2-DSW can also be configured at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 400 Mbps per pair. Further, one FE interface can be configured at 100 Mbps, half duplex, while the other FE interface can be configured at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 300 Mbps per pair.

Identifying Interface Numbers and Addresses

This section explains interface processor slot, FE interface, and interface port numbering.

Note Although the interface processor slots in the Cisco 7000, Cisco 7507, and Cisco 7513 are vertically oriented and those in the Cisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering.

In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. This address is composed of a three-part number in the format interface processor slot number/adapter number/interface port number.

The first number identifies the interface processor slot in which the FEIP2-DSW is installed.
The second number identifies the physical FE interface on the FEIP2-DSW and is slot 0 (on the left) and slot 1 (on the right).

Note To view how FE interfaces are positioned on the FEIP2-DSW, refer to Figure 3 or Figure 4, which show the FEIP2-DSW-2TX and FEIP2-DSW-2FX, respectively.

The third number identifies the FE interface port, which is always numbered as interface 0.

Interface ports on the FEIP2-DSW maintain the same address regardless of whether other interface processors are installed or removed. However, when you move an FEIP2-DSW to a different slot, the first number in the address changes to reflect the new interface processor slot number.

On the FEIP2-DSW-2TX, the first FE interface number is 0 and the second is 1. For example, on a FEIP2-DSW in interface processor slot 3, the address of the first FE interface is 3/0/0 (interface processor slot 3, FE interface 0, and interface port 0). The address of the second FE interface is 3/1/0 (interface processor slot 3, FE interface 1, and interface port 0).

Note If you remove the FEIP2-DSW-2TX from interface processor slot 3 and install it in interface processor slot 2, the addresses of these FE interfaces become 2/0/0 and 2/1/0, respectively.

You can also identify interface ports by physically checking the slot/adapter/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.

Configuring FE Interfaces

This section describes a basic configuration. Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:

 Router# disable

 Router> 

Following is a basic configuration procedure:

Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

 Router# configure terminal

 Enter configuration commands, one per line. End with CNTL/Z.

 Router(config)#

Step 2 At the prompt, specify the first interface to configure by entering the subcommand interface, followed by the type (fastethernet) and slot/port (interface processor slot number/0). The example that follows is for the interface port of the first FE interface port, on an FEIP2-DSW in interface processor slot 1:

 Router(config)# interface fa 1/0/0

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example:

 Router(config-int)# ip address 1.1.1.10 255.255.255.0

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows:

 Router(config-int)# no shutdown

Step 6 Configure additional FE interfaces as required.

Step 7 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.

Step 8 Write the new configuration to nonvolatile memory as follows:

 Router# copy running-config startup-config

 [OK]

 Router#

Following are descriptions and examples of the commands for configuring FE interface 3/0/0. Descriptions are limited to fields that are relevant for establishing and verifying the configuration. After configuring the new FE interface, use show commands to display the status of the new interface or all interfaces, or to verify changes you have made.

Depending on the requirements for your system configuration and the protocols you plan to route on the interface, you might also need to enter other configuration subcommands. For complete descriptions of configuration subcommands and the configuration options available for FE interfaces, refer to the publications listed in the ""If You Need More Information" section.

FE half-duplex operation is the default. To change to full-duplex operation, use the following series of commands:

 Router# configure terminal

 Enter configuration commands, one per line. End with CNTL/Z.

 Router(config)#

 Router(config)# interface fastethernet 3/0/0

 Router(config-if)# full-duplex

 Ctrl-z

 Router#

Using the show interfaces fastethernet command, you can see that the 3/0/0 FE interface is now configured for full-duplex operation:

 Router# sh int fa 3/0/0

 FastEthernet 3/0/0 is administratively up, line protocol is up

   (display text omitted)

 Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX

To return the interface to half-duplex operation, use the no full-duplex configuration command, as follows:

 Router# config t

 Enter configuration commands, one per line. End with CNTL/Z.

 Router(config)# int fa 3/0/0

 Router(config-if)# no full-duplex

 Ctrl-z

 Router#

Using the show interfaces fastethernet command, you can see that the 3/0/0 FE interface is now configured for half-duplex operation:

 Router# sh int fa 3/0/0

 FastEthernet3/0/0 is administratively up, line protocol is up

   (display text omitted)

 Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX

 (display text omitted)

The RJ-45 connection is the default for FEIP2-DSW-2TX (or SC for FEIP2-DSW-2FX). To change to an MII connection and then verify it, use the following series of commands, including the media-type configuration command:

 Router# config t

 Enter configuration commands, one per line. End with CNTL/Z.

 Router(config)# int fa 3/0/0

 Router(config-if)# media-type mii

 Ctrl-z

 Router# sh int fa 3/0/0

 FastEthernet3/0/0 is administratively up, line protocol is up

   (display text omitted)

 Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII

   (display text omitted)

Use the media-type 100 configuration command to return the int
