Route Switch Processor (RSP2) Installation and Configuration Guide [Cisco 7500 Series Routers]

Caution We strongly recommend that you do not use the RSP2 in the Cisco 7507-MX, and Cisco 7513-MX routers. The Cisco 7507-MX and Cisco 7513-MX routers ship by default with an RSP8.

The RSP2 supports the high system availability (HSA) feature, which allows two RSP2s, or an RSP4/4+ and an RSP2, to be used in a Cisco 7507 and Cisco 7513 routers. See the "Configuring High System Availability" section for more information on HSA.

The RSP2 also supports high availability (HA), a series of features that operates similarly to HSA, but which further minimizes system downtime. (HSA is the system default.) For more information on HA, see the "Enabling High Availability Features" section.

With HA or HSA enabled, the RSP2 supports online insertion and removal (OIR).

The RSP2 supports the VIP2 and the VIP4 in the Cisco 7505, Cisco 7507, and the Cisco 7513. (See Figure 1 and Figure 2.)

The RSP2 supports the VIP2 and VIP4 in the Cisco 7000 series routers, and the VIP2, VIP4, and the VIP6-80 in the Cisco 7505, Cisco 7507, and the Cisco 7513 routers. The RSP2 is not supported on the Cisco 7507-MX or the Cisco 7513-MX routers. The RSP2 is not available as an upgrade from an RSP700, or an RSP1. You cannot upgrade to an RSP4/4+, RSP8, or RSP16 from the RSP2.

The RSP2 contains the central processing unit (CPU) and most of the memory components for the router. The Cisco IOS software images reside in Flash memory, which is located on the RSP2:

In the form of a single in-line memory module (SIMM) (U1 in Figure 2)
On up to two PC Cards (called Flash memory cards) that insert in the two PC Card slots (slot 0 and slot 1) in the two PC Card slots (slot 0 and slot 1).

Note For specific Cisco IOS software release compatibility, refer to the "System Software" section and to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl .

Storing the IOS software images in Flash memory enables you to download and boot from upgraded Cisco IOS software images remotely or from software images resident in the RSP2 Flash memory, without having to remove and replace read-only memory (ROM) devices.

The RSP2 also contains:

Most of the additional memory components used by the system, including 16-MB onboard Flash memory and up to two Flash memory cards (16-MB, or 20-MB Flash memory card, with 20-MB being the shipping default).
Air-temperature sensors for environmental monitoring. (All of the logic for the environmental monitoring functions is contained on the router interface card.)

In addition to running the system software from DRAM, the RSP2 contains and executes the following management functions that control the system:

Sending and receiving routing protocol updates
Managing tables and caches
Monitoring interface and environmental status
Providing Simple Network Management Protocol (SNMP) management and the interface between the console and Telnet

The high-speed switching section of the RSP2 communicates with and controls the interface processors on the high-speed CyBus. This switching section decides the destination of a packet and switches it based on that decision. The RSP2 uses a 16-million-instructions-per-second (mips) processor to provide high-speed, autonomous switching and routing.

The RSP2 installs in the following slots on your Cisco 7000 or Cisco 7500 series router:

Slot 4 in the Cisco 7505 router
Slots 2 and 3 in the Cisco 7507 router
Slots 6 and 7 in the Cisco 7513 router

Figure 1 RSP2 (Front-Panel View)

Note A bank of hardware (Media Access Control [MAC]-layer) addresses for the interface ports is contained in an NVRAM device on the router backplane.

Figure 2 Route Switch Processor (RSP2)

CPU

The CPU used in the RSP2 is a Mips R4600 Reduced Instruction Set Computing (RISC) processor with an external clock speed of 50 MHz, and an internal clock speed of 100 MHz.

Memory Components

Table 1 shows the memory components on the RSP2.

Table 1 RSP2 Memory Components

Type	Size/Speed	Quantity	Description	Location (see Figure 2)
DRAM	32-MB¹ to 128-MB SIMMs	1 to 4	32-, or 64-MB SIMMs (based on DRAM required) for main Cisco IOS image functions	Bank 0: U21 and U33 Bank 1: U12 and U4
NVRAM	128 KB	1	Nonvolatile SRAM for the system configuration file²	U18
Flash memory	8-MB SIMM	1	Contains the Cisco IOS images on the RSP2	U1
Flash memory	16-, or 20-, or Flash memory card³	Up to 2	Contains the Cisco IOS images on up to two Flash memory cards⁴	Slot 0 and slot 1
Flash boot ROM⁵	256 KB	1	Flash EPROM for the ROM monitor program image⁶	U30

1 32 MB of DRAM is the default DRAM configuration for the RSP2.

2 A system configuration file is contained in NVRAM, which allows the Cisco IOS software to control several system variables.

3 Only Intel Series 2 Flash memory cards can be used with the RSP2.

4 Type I, Type II, and Type III PC Cards can be used in PC Card slot 1, and Type I and Type II PC Cards can be used in slot 0.

5 The HSA feature requires boot ROM Version 11.1(2) or a later release of 11.1.

6 Downloading ROM monitor images to the Flash boot ROM device is not supported.

DRAM

DRAM stores routing tables, protocols, and network accounting applications and runs the Cisco IOS software. The standard (default) RSP2 configuration is 32 MB of DRAM, with up to 128 MB available through SIMM upgrades. DRAM is contained in up to four SIMM sockets: U21 and U33 (also called bank 0) and U12 and U4 (also called bank 1). When upgrading DRAM, you must use SIMMs from Cisco. (Also see the "Compatibility Requirements" section.)

Caution To prevent memory problems, DRAM SIMMS must be 3.3-volt (V) devices. Do not attempt to install higher-voltage devices in the RSP2 SIMM sockets.

For RSP2 DRAM upgrade procedures, refer to the "Replacing and Upgrading DRAM SIMMs" section.

NVRAM

The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 128-KB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of 5 years. When replacing an RSP2, be sure to back up your configuration to a remote server so you can retrieve it later.

Caution Before you replace an RSP2 in a system with one RSP2, back up the running configuration to a TFTP file server or to Flash memory so you can retrieve it later. If the configuration is not saved, the entire configuration will be lost—inside the NVRAM on the removed RSP2—and you will have to reenter the entire configuration manually. For instructions on how to save the configuration file, see the "Saving and Retrieving the Configuration File" section. This procedure is not necessary if you are temporarily removing an RSP2; lithium batteries retain the configuration in memory until you replace the RSP2 in the system.

Flash Memory

The Flash memory card for the RSP2 is an 16- or 20- Flash memory card, which conforms with the PC Card normally Personal Computer Memory Card International Association (PCMCIA) format.

Both the onboard 8-MB and the 16- or 20-MB Flash memory card (PCMCIA cards) allow you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You can then boot routers either manually or automatically from any of the stored images. Flash memory also functions as a TFTP server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory.

Caution To prevent system problems, use Flash memory cards in the RSP2 that were formatted on an RP, RSP1, or RSP7000 running Cisco IOS Release 11.1(8)CA1 or a later release of 11.1 CA1. You cannot use Flash memory cards on the RSP2 (as storage or boot devices) that were formatted on an RP, RSP1, or RSP7000 using a Cisco IOS boot image earlier than Cisco IOS Release 11.1(8)CA1.

For a list of compatible software releases for the Flash memory card and Flash Disk, refer to the software advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl.

LEDs

Table 2 describes the operation of the LEDs found on the RSP2:

Table 2 RSP2 LEDs

LED Label	Color	State	Indication
Normal¹	Green	On	RSP is on and receiving +5V.
Normal¹	Unlite	Off	No voltage through the board
CPU halt ¹	Yellow	Yellow	RSP2 did not come out of reset; indicates hardware problem with voltage level or PLL phase lock
CPU halt ¹	Unlite	Off	RSP is operating normally.
Master²	Green	On	RSP is an active (HSA/HA configuration required).
Slave	Green	On	RSP is a standby RSP (HSA/HA configuration required).
Slot 0 PC Card	Green	On	PC Card in this slot is being accessed.
Slot 1 PC Card	Green	On	PC Card in this slot is being accessed.

1 The RSP2 controls these LEDs and turns them on in parallel to indicate that the system is operational.

2 If both the Master and Slave LEDs are unlite, the board is inactive.

The Active/Standby switch has been deactivated in software. The reset button boots the system.

PC Card Slots

The RSP2 has two PC Card slots available. Either slot can support a Flash memory card or an input/output (I/O) device. Type I and Type II PC Cards can be used in PC Card slot 0 and slot 1. Type III PC Cards can be used in slot 1. Not all Flash memory cards that are commercially available are supported, and not all I/O devices are supported.

Note Other Flash memory card limitations might apply. For additional Flash memory information, refer to the Flash memory configuration notes listed in the "Related Documentation" section.

Serial Ports

Two asynchronous serial ports on the RSP2, labeled Console and Auxiliary, allow you to connect external terminal devices to monitor and manage the system. The console port is an Electronics Industries Association/Telecommunications Industry Association (EIA/TIA)-232 receptacle (female) that provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.

Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment (DTE) interface; the auxiliary port supports flow control and is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

System Software

The Cisco 7505, Cisco 7507, and Cisco 7513 routers support downloadable system software and microcode for most Cisco IOS software and microcode upgrades. This enables you to remotely download, store, and boot from a new image. The publication Upgrading Software and Microcode in Cisco 7000 Series and Cisco 7500 Series Routers (DOC- 781144=) provides instructions for upgrading over the network or from floppy disks.

Flash memory contains the default system software. An erasable programmable read-only memory (EPROM) device contains the latest microcode version, in compressed form, for each interface processor.

At system startup, an internal system utility scans for compatibility problems between the installed interface processor types and the bundled microcode images. The utility then decompresses the images into running dynamic random-access memory (DRAM). The bundled microcode images then function the same as the EPROM images.

The Cisco IOS software images reside in Flash memory, which is located on the RSP2 in the form of a single in-line memory module (SIMM), on Flash memory cards that insert in the two PC Card slots (slot 0 and slot 1) on the front of the RSP2. (See Figure 2.) Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS images remotely or from software images resident in the RSP2 Flash memory.

Although no monitoring of voltage or temperature is done by the RSP2, a comparator device ensures that voltage is within the normal operating ranges, and three temperature sensors on the RSP2 send temperature information to the chassis interface (CI) card. The CI card reports all voltage and temperature readings, and these readings are available through standard software commands for environmental monitoring. The RSP2 uses a software-controlled configuration register, so you do not have to remove the RSP2 to configure jumpers. There are no user-configurable jumpers on the RSP2.

Note The exception to this is CIP microcode, which, as of Cisco IOS Release 11.1(1), is unbundled from the Cisco IOS software image bundle, and is available in a separate bundle on floppy disks, a TFTP server, Cisco.com, or PC Card-based Flash memory media.

For the latest software release information, refer to the hardware/software compatibility matrix at http://www.cisco.com/pcgi-bin/front.x/Support/HWSWmatrix/hwswmatrix.cgi.

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 to people 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.

Preventing Electrostatic Discharge Damage

Electrostatic Discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, can result in complete or intermittent failures. Each processor module contains a printed circuit card that is fixed in a metal carrier.

Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use an ESD-preventive wrist or ankle strap whenever you handle any electronic system component.

Following are guidelines for preventing ESD damage:

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
When you work at the interface processor end of the router, connect the equipment end of the strap to the captive installation screw on an installed interface processor, or to the chassis grounding receptacle that is located next to each power supply.
When you install a processor module, use the ejector levers to properly seat the bus connectors in the backplane, and then tighten both captive installation screws. These screws prevent accidental removal, provide proper grounding for the system, and help to ensure that the bus connectors are seated in the backplane.
Handle processor modules by the carrier handles and carrier edges only; never touch the board or any connector pins.
When you remove a processor module, place it component side up on an antistatic surface or in a static shielding bag. Immediately place the module in a static shielding bag if you need to return it to the factory.
Avoid contact between electronic equipment and clothing. Antistatic straps only protect the equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.

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

Compatibility Requirements

This section describes important compatibility requirements for the RSP2.

Chassis Slot and DRAM Requirements

Following are chassis slot and DRAM requirements for ensuring RSP2 compatibility.

You have no restrictions on installing an RSP2 in a Cisco 7505. However, the Cisco 7505 does not support the HSA or the HA features.
You have no restrictions on installing an RSP2 in a Cisco 7507 provided that you install the RSP2 in slot 2 or slot 3, or both. With the HSA or HA features enabled, you will install an RSP2 (or an RSP4/4+ and an RSP2) in both RSP slots.
You have no restrictions on installing an RSP2 in a Cisco 7513 provided that you install the RSP2 in slot 6 or slot 7, or both. With the HSA or HA features enabled, you will install an RSP2 (or an RSP4/4+ and an RSP2) in both RSP slots.
It is assumed that if you install two RSP2s (or am RSP4/4+ and an RSP2) in the Cisco 7507 or Cisco 7513, you plan to enable and configure the HSA or HA features.

Memory Requirements

Flash memory cards and DRAM SIMMs must meet the following requirements:

Flash memory cards and DRAM SIMMs must be obtained from Cisco Systems. Flash memory cards are available in 16 MB or 20 MB, with 16 MB being the shipping default. See the "PC Card Slots" section for additional information on supported Flash memory cards.
Maximum DRAM speed is 60 nanoseconds (ns), maximum SIMM height is 1 inch (2.54 centimeters), and maximum DRAM SIMM voltage is 3.3 volts (V).
The minimum required DRAM configuration for the RSP2 is 32MB.
Flash memory cards and DRAM SIMMs must be obtained from Cisco Systems. See the "PC Card Slots" section for additional information on supported PC Cards.
You cannot use a Flash memory card that was formatted on another RSP-based system, such as the RSP7000, or RSP1 which is running a boot or Cisco IOS software image earlier than 10.3(6) or a later release of Cisco IOS release 10.3.
You must first reformat the Flash memory card, formatted on one of these other RSP-based systems, before you can use it as a boot or storage source with the RSP2. Refer to Flash Memory Card Installation Instructions (part number DOC-782083=) for instructions on reformatting a Flash memory card.
The HSA and HA features require that the boot read-only memory (ROM) device (U30, shown in the "System Software" section) be updated to Version 11.1(2) or a later release of 11.1.

To check the boot ROM (also called the system bootstrap) version currently running on your RSP2, use the show version command and check the boot ROM version number as follows:

 Router# show version

 (display text omitted)

 System Bootstrap, Version 11.1(2)

Software Prerequisites

The minimum supported Cisco IOS release compatible with the RSP2 is 10.3(6) or a later release of Cisco IOS release 10.3. For the latest compatible software releases, refer to the software advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl .

Note The 32-MB Flash memory card is compatible with Cisco IOS Release 12.1(5)T1 or a later release of Cisco IOS Release 12.1 T.

Use the show version and show hardware commands to display the router's current hardware and software configurations. The show microcode command lists the bundled microcode (and target hardware) version for each processor type. The show controller cbus command shows the microcode version you are running. The show diagbus command shows the RSP2 board's hardware version and revision.

For additional descriptions of show commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, or as printed documents.

Note If the required system software and microcode are not available in your system, contact a customer service representative for upgrade information. (To obtain assistance, see the "Obtaining Technical Assistance" section on page 86.)

Hardware Prerequisites

Your router configuration, protocols and features might require more than the 32 MB of DRAM that is shipped with the RSP2. To upgrade DRAM, see the "Software Configuration Register Settings" section.

To ensure proper operation of a system configured for HSA or HA, note the guidelines below:

With HSA and HA, the RSP2 can interoperate with another RSP2, with an RSP4, or with an RSP4+.
To ensure that the standby RSP2 operates properly, the active and the standby RSP2 (or the RSP2 and the RSP4/4+) should have the same DRAM configuration and boot ROM version.
Removing the active RSP2 while the system is operating might cause the system to crash; however, the system reloads with the standby RSP2 as the new active RSP2. To prevent system problems, do not remove the active RSP2 while the system is operating.

Caution Before using a Flash memory card previously formatted and used in an RSP, RSP7000, or RSP1, you must reformat the Flash memory card. Flash memory cards formatted on any of these processors do not work properly in an RSP2. You must first reformat it on your RSP2 system. Refer to Flash Memory Card Installation Instructions (part number DOC-782083=) for instructions on reformatting Flash memory.

Microcode Requirements

Microcode is a set of processor-specific software instructions that enables and manages the features and functions of a specific processor type. At system startup or reload, the system loads the microcode for each processor type present in the system. The latest available microcode image for each processor type is bundled and distributed with the system software image.

Note Overriding the bundle can result in incompatibility among the various interface processors in the system. We recommend that you use only the microcode image that is bundled. The exception to this is CIP microcode, which as of Cisco IOS Release 11.1(1), is unbundled from the IOS software image bundle, and is available in a separate bundle on floppy disks, a TFTP server, CCO, or Flash memory cards.

Installing the RSP2

The following sections describe the procedures for installing or replacing an RSP2. Ensure that your system meets the minimum software, hardware, and microcode requirements described in the following: "Software Prerequisites" section, "Hardware Prerequisites" section, and "Microcode Requirements" section. Proceed to the "Removing the RSP2" section for instructions on removing the RSP2, and then to the "Replacing the RSP2" section for installation instructions. After the new RSP2 is secure, follow the procedures in the "Troubleshooting the Installation" section to verify that it is installed and functioning properly.

Caution Removing the only installed RSP2 from a system while the system is operating will cause the system to crash. Consider this before removing an RSP2 while the system is operating. To ensure that the standby RSP2 operates properly with the full system configuration should the active RSP2 ever fail, the standby RSP2 must have the same DRAM and the same (or higher) Flash memory capacity as the active RSP2. See the "Memory Components" section for RSP2 memory component requirements.

Note The carriers on processor modules have EMI fences for EMI shielding; therefore, they fit very tightly in the chassis slots. To ensure that you can properly remove or install an RSP2 in RSP slot 7 from the Cisco 7513 router, we recommend that you proceed as follows: first remove an interface processor installed in slot 8, remove or install the RSP2 in RSP slot 7 (and fasten its captive installation screws as appropriate), and then reinstall the interface processor in slot 8.

List of Parts and Tools

You need some or all of the following parts and tools to remove and replace an RSP2 or to upgrade DRAM. If you need additional equipment, contact a customer service representative for ordering information.

An RSP2 or related product listed in the "Connecting the Console Terminal" section.
DRAM SIMMs from Cisco if you are replacing SIMM, as described in the "Replacing and Upgrading DRAM SIMMs" section. (Also see the "Compatibility Requirements" section.)

Caution To prevent memory problems, DRAM SIMMs must be 3.3-volt (V) devices. Do not attempt to install higher-voltage devices in the RSP2 SIMM sockets.

Number 2 Phillips or 3/16-inch flat-blade screwdriver for the captive installation screws that secure the RSP2 in its slot.
ESD-prevention equipment or the disposable ESD-preventive wrist strap included with all spares and upgrade kits.
Antistatic mat, foam pad, or bag for the removed RSP2 (place the removed RSP2 into an antistatic bag if you plan to return it to the factory, or on an antistatic mat or foam if you are replacing components and will reinstall the RSP2).
DRAM SIMMs from Cisco if you are replacing SIMMs.

Removing the RSP2

When you remove or install the RSP2, be sure to use the ejector levers, which help to ensure that the RSP2 is fully inserted in the backplane or fully dislodged from it. An RSP2 that is only partially connected to the backplane can halt the system unless a second RSP2 is installed.

Figure 3 shows a detail of the ejector lever mechanism that is appropriate for the router. When you simultaneously push the ejector levers inward (toward the carrier handle), the levers push the RSP2 into the slot and ensure that the board connectors are fully seated in the backplane. Follow these steps to remove the RSP2:

Step 1 Optional step: If you are replacing the RSP2 in a system with one RSP2, copy the currently running configuration file to a TFTP server so you can retrieve it later. (See the "Saving and Retrieving the Configuration File" section.)

Step 2 Attach an antistatic strap to yourself and then connect the equipment end of the strap to a captive installation screw on an installed interface processor, or to any unfinished chassis surface.

Step 3 If you are replacing the RSP2, disconnect any devices that are attached to the console or auxiliary ports. If you are removing the RSP2 for maintenance and will reinstall the same one, you can leave the devices attached provided that doing so will not strain the cables.

Step 4 Use a screwdriver to loosen the two captive installation screws. (See Figure 3.)

Step 5 Place your thumbs on the ends of each of the ejectors and simultaneously pull them both outward, away from the carrier handle (in the opposite direction from that shown in Figure 3c) to release the carrier from the slot and to dislodge the RSP2 from the backplane.

Step 6 Grasp the handle of the RSP2 with one hand and pull the RSP2 straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 4.) Keep the carrier parallel to the backplane. Avoid touching the board or any connector pins.

Figure 3 Ejector Levers and Captive Installation Screw

Step 7 Place the removed RSP2 on an antistatic mat or foam. If you plan to return the RSP2 to the factory, immediately place it in an antistatic bag to prevent ESD damage.

Step 8 Attach the equipment end of the ESD-preventive strap to the RSP2 before performing any maintenance on the RSP2 that might create an ESD hazard.

This completes the removal procedure. If you removed the RSP2 to replace SIMMs, proceed to the "Software Configuration Register Settings" section. If you are replacing the RSP2, proceed to the next section to install the new RSP2.

Replacing the RSP2

The RSP2 is keyed for installation only in an RSP slot. By default, the system active is the RSP that occupies the first RSP slot in the router: slot 2 in the Cisco 7507, and slot 6 in the Cisco 7513. Follow these steps to install an RSP2:

Step 1 Grasp the RSP2 handle with one hand and place your other hand under the carrier to support and guide it into the slot. (See Figure 4.) Avoid touching the board or any connectors.

Step 2 Place the back of the RSP2 in the appropriate RSP slot and align the notches along the edge of the carrier with the grooves in the slot. (See Figure 3a.)

Figure 4 Handling the RSP2 During Removal and Installation

Caution To prevent damage to the backplane, you must install the RSP2 in one of the two RSP slots on the router. The slots are keyed for correct installation. Forcing the RSP2 into a different slot can damage the backplane and the RSP2.

Step 3 While keeping the RSP2 parallel to the backplane, carefully slide the carrier into the slot until the RSP2 faceplate makes contact with the ejector levers, and then stop. (See Figure 3b.)

Step 4 Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously push both ejector levers inward (toward the handle) until they are parallel to the faceplate. (See Figure 3c.)

Step 5 Use a screwdriver to tighten the captive installation screws on the ends of the RSP2. (See Figure 3a.)

Step 6 Use a screwdriver to tighten the two captive installation screws on the RSP2 faceplate to prevent the RSP2 from becoming partially dislodged from the backplane and to ensure proper EMI shielding. (These screws must be tightened to meet EMI specifications.)

Step 7 If you disconnected the console terminal to remove the RSP2, or if you are installing a new RSP2, connect the console terminal to the console port. (See the "Connecting the Console Terminal" section.)

Step 8 Ensure that a console terminal is connected (see the "Connecting the Console Terminal" section) and that it is turned on.

Step 9 Turn the system power back on, and proceed to the "Restarting the System" section to check the installation.

This completes the procedure for replacing the RSP2.

Connecting the Console Terminal

The system console port on the RSP2 is a DCE DB-25 receptacle for connecting a console terminal, which you need to configure in order to communicate with your system. The console port is located on the RSP2 to the right of the auxiliary port, as shown in Figure 5, and is labeled Console.

Before connecting the console port, check the documentation for your terminal to determine the baud rate of the terminal you are using. The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600,8N2).

Use the console cable provided to connect the terminal to the console port on the RSP2, and then follow the steps in the "Restarting the System" section.

Figure 5 Console and Auxiliary Port Connections

Note The console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

Connecting to the Auxiliary Port

The auxiliary port on the RSP2 is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a channel service unit [CSU], data service unit [DSU], or other router) to the router. The port is located above the console port on the RSP2 and is labeled AUX. An example of a modem connection is shown in Figure 5.

Using the Y-Cables for Console and Auxiliary Connections

For systems with two RSP2s installed and the HSA or HA feature enabled, you can connect to either the console or auxiliary ports simultaneously on both RSPs using a special, optional Y-cable. If only one RSP2 is installed, it is the system active by default.

Note The Y-cables are not required; two individual console cables and two individual auxiliary cables can be used instead.

Figure 6 shows the console Y-cable and Figure 7 shows the auxiliary Y-cable.

Figure 6 Console Y-Cable (Part Number CAB-RSP2CON=)

Figure 7 Auxiliary Y-Cable (Part Number CAB-RSP2AUX=)

Restarting the System

When you turn the system power back on, verify that the system boots and resumes normal operation. If you are restarting the system after upgrading the DRAM, expect that it will take the system longer to complete the memory initialization portion of the boot sequence with more DRAM. (See the "Verifying System Startup Sequence" section.)

Follow these steps to verify that the RSP2 is installed and functioning properly:

Step 1 Check the RSP2 connections to make sure they are secure:

The RSP2 is inserted all the way into its slot, and both the captive installation screws are tightened.
The console terminal is turned on and is connected to the console port.

Step 2 Observe the RSP2 LEDs. While the system initializes, the CPU halt LED on the RSP2 stays on. It goes off when the boot process is complete. As the RSP2 initializes each interface processor, the status LEDs on each interface processor go on and off in irregular sequence.

Step 3 For a Cisco 7507 or Cisco 7513 with HSA or HA configured, verify that the console terminal displays the system banner and startup screen as the system restarts.

The active console display should look similar to the following for a Cisco 7513 (note the RSP2 slots indicated):

Step 5 After the system boots the software and initializes the interface processors, verify that the RSP2 LEDs are in the following states:

RSP2 normal LED is on (for each RSP2 installed).
CPU halt LED is off (for each RSP2 installed).
Active RSP2 active LED is on (if HSA or HA is configured).
Standby RSP2 standby LED is on (if HSA or HA is configured).

Step 6 Verify that all the enabled LEDs (on the interface processors) are on.

Step 7 In systems with a second RSP2 installed (and HSA or HA configured), use the show version command to verify that the standby RSP2 is recognized by the system. Following is a sample from a Cisco 7513:

 Slave in slot 7 is running Cisco Internetwork Operating System Software

(Note that this could also be "slot 6" depending on which RSP2 is configured as the slave or the recent crash history of your router.)

When you have verified all the conditions in Step 2 through Step 6 (or Step 7 if you have a second RSP2 installed and want to use the HSA or the HA features), the installation is complete. If you replaced the RSP2 and saved your configuration file to a remote server before doing so, see the "Retrieving the Configuration File" section. If you replaced the RSP2 and did not save the configuration, use the configure command or the setup command facility to reenter the configuration information.

An error condition exists if no LEDs go on at power up or after initialization, or if the CPU halt LED goes on and remains on. If this happens, proceed to the "Troubleshooting the Installation" section to try to isolate the problem.

For more complete configuration information, refer to the Configuration Fundamentals Configuration Guide and the Configuration Fundamentals Command Reference publications, which are available on the Documentation CD-ROM or as printed documents.

If you have a second RSP2 installed, you must configure the HSA (or HA, if you prefer) features for your Cisco 7507 or Cisco 7513 router. Read the following caution, and then proceed to the following section, "Configuring High System Availability" section.

Caution When you install a second RSP2 card for the first time and plan to enable the HSA or HA features, you must immediately configure it correctly. See the "Configuring High System Availability" section, or the "Enabling High Availability Features" section. This ensures that the new standby is configured consistently with the active. Failure to do so may result in an unconfigured standby RSP2 (or RSP4/4+) taking over the router when the active fails, rendering the network inoperable.

This completes the procedure for restarting the system.

Configuring the Router for a Single RSP2

If you have a single RSP2, you can configure your system according to the Cisco IOS release appropriate for your router. See the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware at http://www.cisco.com/univercd/cc/td/doc/product/software/index.htm .

If you have more than one RSP2 (or an RSP2 and an RSP4/4+), and you are using a Cisco 7507 router or a Cisco 7513 router, you must configure your router for either high system availability (HSA) the default, (see the "Configuring High System Availability" section), or high availability (HA), (see the "Enabling High Availability Features" section).

Using the EXEC Command Interpreter

Before you configure your system using the EXEC-level commands, you must enter the privileged level of the EXEC command interpreter using the enable command. The system prompts you for a password if one has been set. The system prompt for the privile
