Installing a Router

This section explains the procedures for installing Cisco 12006 and Cisco 12406 Routers and contains the following sections:

•Installing the Rack-Mount Brackets (Optional)

•Installing the Chassis in a Rack

•Installing Center-Mount Brackets (Optional)

•Installing the Chassis on a Tabletop or Flat Surface

Before installing Cisco 12006 and Cisco 12406 Routers, see Chapter 2, "Preparing for Installation," for information on environmental considerations and requirements.

Ensure the following before you install the router:

•The exhaust vents on the blower module mounted at the rear of the chassis are not blocked.

•The air filter is mounted on the right side as you face the router; air flow to the blower module is not blocked.

•There is 24 inches (61 cm) of clearance at the rear of the chassis so you can read the blower module LEDs and perform maintenance on the module.

•There is 24 inches (61 cm) of clearance in front of the router chassis to enable working with line cards and power supplies, and attaching Network Interface Cable (NICs) or other components.

•Location is temperature controlled, air conditioned, and dust free.

•Power cables and power supplies have been checked for compatibility with your power service.

•Labels on the equipment have been checked to ensure that the power service at your site is suitable for the router.

•AC power source receptacles are easy to reach.

---

Warning Do not mix power module input types in the router. All power modules installed in a router must be either AC-input power supplies or DC-input PEMs.

---

Installing the Rack-Mount Brackets (Optional)

The router accessory kit includes a pair of rack-mount brackets that can be used as a temporary aid to bear the weight of the router while it is being positioned in the equipment rack and secured. The use of these mounting brackets is optional; you can install the router in the rack without using these brackets. These brackets can be left in place following router installation.

Tools and Equipment Required

You need the following items to install the optional rack-mount brackets:

•Number 2 Phillips screwdriver

•Tape measure (optional)

•Level (optional)

Installing the Optional Rack-Mount Brackets

To install the rack-mount brackets, see Figure 3-1 and follow these steps:

---

Step 1 Measure and mark the hole at the same height on both the left and right rack rails.

Step 2 Mount the right mounting bracket:

a. Hold the right rack-mount bracket against the right rack rail and align the bottom screw hole in the bracket with the marked screw hole on the rail.

b. Insert a screw through the bottom hole in the bracket and finger tighten the screw.

c. Insert and finger tighten a second screw in the top hole in the bracket.

Step 3 Follow Step 2a through Step 2c to mount the left rack-mount bracket.

Step 4 Use a level to verify that the tops of the two brackets are level, or use a measuring tape to verify that both brackets are the same distance from the tops of both rack rails.

Step 5 Use a screwdriver to tighten all the screws.

---

Figure 3-1 Installing the Optional Rack-Mount Brackets

Installing Center-Mount Brackets (Optional)

To install the Cisco 12006 or Cisco 12406 Router in the center-mount position, you must first install the upper and lower center-mount brackets on the equipment rack rails, then secure the chassis to the center-mount brackets. (See Figure 3-2.) If you do not plan to use the optional center-mount brackets, proceed directly to the "Installing the Chassis in a Rack" section.

Figure 3-2 Lower and Upper Center-Mount Brackets

The optional center-mount bracket installation kit ships in an accessories box included in the router shipping container. If any parts are missing, contact a Cisco service representative for assistance.

Tools and Equipment Required

You need the following items to install the optional center-mount rack-mounting brackets:

•Number 2 Phillips screwdriver

•Tape measure (optional)

•Level (optional)

Installing the Optional Center-Mount Brackets

To install the center-mount brackets, see Figure 3-2 and follow these steps:

---

Step 1 Measure and mark the hole at the same height on both the left and right posts.

---

Caution When installing the right side lower center-mount bracket, ensure that the bracket does not impede airflow through the air filter, which could cause overheating in the router.

---

Step 2 Mount the lower right bracket:

a. Hold the lower right bracket against the right rack rail and align the bottom screw hole in the lower bracket with the marked screw hole.

b. Pick a bottom bracket hole that aligns with a hole in the rack rail, then insert a screw in the hole and finger tighten the screw.

c. Insert a second screw in the top hole in the bracket and finger tighten that screw.

Step 3 Repeat Step 2a through Step 2c to mount the lower left center-mount bracket so that it is at the same height as the lower right bracket.

Step 4 Use a level to verify that the tops of the two brackets are level, or use a measuring tape to verify that both brackets are the same distance from the tops of both rack rails.

Step 5 Use a screwdriver to tighten all the screws.

Step 6 Repeat Step 1 through Step 5 for both upper center-mount brackets.

---

Installing the Chassis in a Rack

This section explains how to install Cisco 12006 and Cisco 12406 Routers in a rack. This procedure assumes you have unpacked the router using the Cisco 12006 and Cisco 12406 Router Unpacking and Repacking Instructions (Document number 78-16104-xx) posted on the outside of the shipping container.

You mount the chassis in the equipment rack by setting the chassis in position against the rack rails and then securing it to the rack or optional center-mount brackets with screws through holes in the rack-mounting flanges on either side of the chassis. To accommodate racks with different hole patterns in their rails, the chassis rack-mounting flanges have two groups of eight oblong screw holes on either side. (See Figure 3-3.) The mounting holes in the chassis flanges are spaced so that one mounting hole in each hole group aligns with a hole in the rack rail or optional center-mount bracket. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.

Figure 3-3 Chassis Mounting Bracket Holes

To install the chassis in a rack, see Figure 3-3 and follow these steps:

---

Step 1 Move the router as close to the installation location as possible without interfering with the installation process.

Step 2 With one person lifting from the front and one from the rear of the chassis, grasp the front and rear of the chassis, lift the chassis off the pallet, and position the chassis in the rack.

---

Note A third person might be needed to assist in lifting and positioning the chassis in the rack.

---

Step 3 Install the screws to secure the chassis to the rack:

a. Look at the bottom mounting holes on the chassis rack-mount flanges. Align one of the holes with a mounting hole in the rack.

b. Install one of the mounting screws provided.

c. On the other side of the chassis, adjust the position of the chassis so that the same mounting hole in the bottom group of mounting holes is aligned with a hole in the rack.

d. Install one of the mounting screws provided.

Step 4 Repeat Step 3a through Step 3d for additional mounting holes.

---

Caution Do not allow the chassis to hang free until you have installed a screw in all four hole groups (at least two screws on each side of the chassis).

---

Step 5 Use a screwdriver to tighten all the screws.

---

Installing the Chassis on a Tabletop or Flat Surface

Follow the steps below to install a Cisco 12006 Router or Cisco 12406 Router on a tabletop or stable flat surface. You can use the same mounting hardware that secured your router to the shipping pallet to secure the chassis to a flat surface.

---

Step 1 Move the router as close to the installation location as possible.

---

Caution Do not lift the chassis by the blower module handle. This handle is designed to support only the weight of the blower module.

---

Step 2 With one person positioned at the front of the chassis and one at the rear, lift the chassis off the pallet and position the chassis on the flat surface.

Step 3 Secure the chassis to the flat surface to ensure that it does not fall off.

---

Supplemental Bonding and Grounding Connections

If the router is installed in a network equipment building system (NEBS) environment, follow the guidelines in this section. For installations other than in a NEBS environment, you may chose to rely on the safety earth ground connection supplied via the International Electrotechnical Commission (IEC) 320 inlets for AC-powered units and the main terminal block ground connection for DC-powered units.

Even though the router chassis requires a safety earth ground connection as part of the power cabling to the PDU, we strongly recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding receptacle on the router chassis, which satisfies the Telcordia NEBS requirement for supplemental bonding and grounding connections. This receptacle consists of three threaded inserts located on the side of the chassis near the back panel. (See Figure 3-4.)

Figure 3-4 Supplemental Bonding and Grounding Port for NEBS Compliance

Use a dual-hole lug to connect to the chassis with two 6.3-mm (M6) screws on the 0.63-inch (16-mm) centers as shown in Figure 3-4 and Figure 3-5. The lug can be ordered from Cisco (Part Number 32-0607-01).

Figure 3-5 Cable Lug

The dual-hole lug is crimped onto a grounding wire of a wire size and length determined by your router location and facility environment. The crimping tool shown in Figure 3-6 is a standard crimping tool obtainable from many sources.

Figure 3-6 Crimping the Lug

---

Note The three threaded inserts that make up the grounding receptacle are set in a triangle so that you can choose any two of the three holes to attach the lug and grounding cable.

---

Connecting RP and Line Card Cables

To connect RP and line card cables, see Figure 3-7 and follow these steps:

---

Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.

Step 2 Proceeding from left to right, identify the cables that attach to the first RP or line card.

Step 3 Carefully route the interface cable through the chassis cable-management bracket and across the card to the card interface port; do this for one cable at a time.

Figure 3-7 Chassis Cable-Management Bracket

Step 4 Proceeding from left to right, identify the cable that connects to each card port and connect the cable to the RP or line card port.

Step 5 Proceeding from left to right, carefully wrap the cables into the line card cable-management bracket using the velcro straps.

---

Caution Carefully adjust the cable in the cable-management brackets to prevent any kinks or sharp bends in the interface cable. Kinks and sharp bends can destroy or degrade the ability of the optical fiber to propagate the signal-encoded beam of light accurately from one end of the cable to the other. Also, allow adequate strain relief in the interface cable.

---

Step 6 Route the cable through the fingers on the vertical chassis cable-management bracket and turn the latch on the front of the bracket to secure the cables in the bracket.

---

Connecting Alarm Card Cables

Cisco 12006 and Cisco 12406 Routers have two alarm cards located in the two slots immediately above the left power supply bay and directly below the clock and scheduler card slots. Each alarm card is equipped with a standard DB-9 connector, labeled ALARM. This connector can be used to connect the router to an external site alarm maintenance system so that any critical, major, and minor alarms generated in the router also energize alarm relays on the alarm card and activate the external site alarm. Appendix A, "Technical Specifications," lists the pin-to-signal correspondence between the connector pins and the alarm card relay contacts.

Because alarm contact cables are entirely dependent on installation site circumstances, alarm connector cables are not available from Cisco Systems.

---

Note Only safety extra-low voltage (SELV) circuits can be connected to the alarm connector. Maximum rating for the alarm circuit is 2A, 50VA.

---

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, you must use a shielded cable when connecting to the external alarm ports on the alarm card. The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to both connectors.

---

Connecting to the Console and Auxiliary Ports

This section provides the information for connecting console terminals and other auxiliary devices to the console and auxiliary ports on the router. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The console port does not support modem control or hardware flow control. GRP ports are discussed below. PRP ports are discussed in the "PRP Console and Auxiliary Ports" section.

GRP Console and Auxiliary Ports

This section provides connection equipment and pin designation information for the console and auxiliary ports on the Gigabit Route Processor (GRP).

---

Note To maintain Class B, EMI compliance, shielded cables must be used on the console and auxiliary ports of the GRP= and GRP-B=.

---

The GRP has two EIA/TIA-232 ports:

•DCE DB-25 receptacle for connecting a console terminal

•DTE DB-25 plug for connecting other DTE devices

The DCE-mode console port is a DCE DB-25 receptacle used for connecting a console terminal, which you will need to configure the router.

The DTE-mode auxiliary port is a DTE DB-25 plug for connecting a modem or other DCE device (such as a channel service unit/data service unit [CSU/DSU] or another router) to the router.

---

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.

---

Figure 3-8 GRP Console DCE and Auxiliary DTE Port Connections

Check your terminal documentation to determine the baud rate of the terminal you plan to use. If your documentation does not specify settings, use the following terminal settings: 9600 baud, 8 data bits, no parity, and 2 stop bits. You will need an EIA/TIA-232 DCE console cable to connect the terminal to the console port.

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, and Ethernet interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

---

GRP Console Port Signals

The console port on the GRP requires a straight-through EIA/TIA-232 cable. Table 3-1 lists the signal-to-pin correspondence for the GRP console port.

Table 3-1 GRP Console Port Pin Signals

GRP Auxiliary Port Signals

The GRP auxiliary port is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to the router. The auxiliary port is located next to the console port on the GRP card. The auxiliary port supports hardware flow control and modem control. An example of a modem connection is shown in Figure 3-8. Table 3-2 lists the signal-to-pin correspondence for the auxiliary port.

---

Note To maintain Class B EMI compliance, shielded cables must be used on the console and auxiliary ports of the GRP= and GRP-B=.

PRP Console and Auxiliary Ports

The system console port on the PRP is a DCE RJ-45 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in Figure 3-9. Before connecting the console port, check the documentation for your terminal to determine the baud rate.

If your documentation does not specify settings, use the following terminal settings: 9600 baud, 8 data bits, no parity, and 2 stop bits. The console port requires a rollover RJ-45 cable.

Figure 3-9 PRP Console and Auxiliary Port Connections

1	Modem	4	Auxiliary port
2	Console terminal	5	Console port

---

Note The console and auxiliary ports are both 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.

---

---

Caution The ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits.

---

---

Note RP cables are not available from Cisco, but are available from any commercial cable vendor.

---

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, Ethernet, and BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

---

PRP Console Port Signals

The console port on the PRP is a DCE RJ-45 receptacle. Table 3-3 lists the signal-to-pin correspondence for the PRP console port.

Installing a Flash Memory Card

By default, a Flash memory card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0 before the router is shipped. (See Figure 3-10.) PCMCIA slot 0 (SLOT-0) is the bottom slot and slot 1 (SLOT-1) is the top slot. Both Flash memory card slots on each RP can be used at the same time.

The software configuration register is set to 0x0102, which causes the router to boot automatically from the Cisco IOS software image stored on the Flash memory card.

Figure 3-10 Flash Memory Card Slot Opening

Ensure that a console terminal is connected to the RP console port and turned on, or that you have a remote login to the router from another device through a Telnet session.

Connecting the GRP to an Ethernet Network

This section provides information for connecting the GRP to an Ethernet network. Figure 3-11 shows the RJ-45 and MII Ethernet ports on the GRP.

Figure 3-11 RJ-45 and MII Ethernet Connections

The GRP has one Ethernet port, which uses either of these port connectors:

•RJ-45 receptacle—An 8-pin media-dependent interface (MDI) RJ-45 receptacle for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u 100BASE-TX (100 Mbps) connection.

•MII receptacle—A 40-pin media independent interface (MII) receptacle that provides additional flexibility in Ethernet connections. This connector can also be used for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u 100BASE-TX (100 Mbps) connection.

---

Note The RJ-45 and MII receptacles on the GRP represent two physical connection options for one Ethernet interface; you can use either the MDI RJ-45 connection or the MII connection, but not both simultaneously. The transmission speed of the Ethernet port is set through an auto-sensing scheme on the GRP.
The speed is determined by the network to which the Ethernet interface is connected, and is not user-configurable. Moreover, even at the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides maximum usable bandwidth of less than 100 Mbps. Expect a maximum usable bandwidth of approximately 20 Mbps when using either the MII or RJ-45 connection.

---

The Ethernet port can use either unshielded twisted-pair or screened twisted-pair cable. In sites where extremely high immunity to noise is required, screened twisted-pair cable is recommended. Figure 3-12 shows the layout of the Ethernet MII receptacle on the GRP.

Figure 3-12 Ethernet MII Receptacle

Table 3-5 lists the signal-to-pin correspondence for the Ethernet MII connector.

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

---

Connecting the PRP to an Ethernet Network

This section provides information for connecting the PRP on your router to an Ethernet network.

The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub. To connect cables to the PRP Ethernet interfaces (ports labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP.

RJ-45 cables are not available from Cisco Systems, but are available from outside commercial cable vendors.

---

Note Use cables that comply with EIA/TIA-568 standards. (See Table 3-8 and Table 3-9 for cable recommendations and specifications.)

---

---

Caution The Ethernet ports are used primarily as Telnet ports into the router, and for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

---

Figure 3-14 shows an example of the functionality of an Ethernet port. In this example, you cannot access Network 2.0.0.0 via the Ethernet port (ETH0) on the PRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 3-14.)

To access Network 2.0.0.0 from Router A, use an interface port on one of the line cards (in this example, a Packet-over-SONET [POS] line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 3-14.)

PRP Ethernet Connections

Figure 3-15 shows a PRP RJ-45 receptacle and cable connector. The RJ-45 connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Table 3-7 lists the signal-to-pin correspondence for the RJ-45 receptacle.

Connecting to an AC Power Source

This section presents the procedure for connecting your router to an AC power source. A power factor corrector (PFC) allows the AC-input power supply to accept AC power source voltage from an AC power source operating between 100 and 240 VAC, 20-Amp service in North America; and a range of from 185 to 264 VAC, 16-Amp service in an international environment.

---

Caution The AC-input power supply weighs 14 pounds (6.4 kilograms). Use two hands when handling a power supply.

---

---

Warning The AC-input power supply power standby switch should be in the OFF position.

---

When operating your router on a power source, the power supply bays must have one of the following power combinations installed before operating the router:

Table 3-10 Required Power Combinations

Router Power	Combination
AC power	1 AC-input power supply 1 power supply blank
	2 AC-input power supplies
DC power	1 DC-input PEM 1 PEM blank
	2 DC-input PEMs

2	AC power cord receptacle A	5	Guide pin
3	AC power cord receptacle B	6	Blower module connector

To connect AC power to the AC PDU on the router, see Figure 3-18 and follow these steps:

---

Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.

Step 2 Locate the two AC power cords and remove them from their shipping packaging. Verify that the AC power cords shipped with the power supplies are the correct type for your site.

---

Note If you have received the wrong type of AC power cord, contact your service representative for a replacement.

---

Step 3 Plug the socket end of each AC power cord into a receptacle on the PDU. (See Figure 3-18.)

Step 4 Insert the plug end of each AC power cord into the AC power source outlet.

For full redundancy, connect each AC-input power supply to an independent power circuit with its own circuit breaker. We also recommend that you use an uninterruptable power source (UPS) to protect against power failures at your site.

Step 5 Verify that the AC power source circuit breaker servicing each of the AC-input power supplies is switched on.

---

---

Note When operating your router on a single power module, the second power module bay must have a blank filler (MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.

---

Connecting to a DC Power Source

This section provides the procedure for connecting the router to a DC power source.

---

Warning The circuit breaker switch on the faceplate of the DC-input PEM should be in the OFF position.

---

To connect source DC power to the DC PDU, see Figure 3-19 and Figure 3-20 and follow these steps:

---

Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.

Step 2 Locate the DC PDU on the back of the router. The PDU is positioned directly below and behind the blower module.

2	Positive terminal port	4	Terminal port connector screws

Step 3 Connect the source DC power leads to the three terminal ports in the DC power connector block (see Figure 3-20) in this order:

•Ground lead first (bottom port on the connector block)

•Positive lead second (middle port on the connector block)

•Negative lead last (top port on the connector block)

a. Push the lead into the connector block port.

b. Use a flat-blade screwdriver to tighten the set screw and secure the lead.

c. Repeat Step 3a and Step 3b for the remaining leads and for the second PDU connector block.

Step 4 Verify that the source DC circuit breaker servicing the DC PDU is switched on.

Power On the Router

To power on the router, follow these steps:

---

Step 1 Either switch on all the circuit breakers or plug the power cord into an active power source that controls power to the PDU in the router.

During the first-time startup, the system displays the system banner information. Check the startup banner and displays to ensure that the system has restarted properly and that all the interfaces reinitialize properly.

Step 2 Check the power module LEDs. They should appear as described below:

•For a router equipped with AC-input power supplies:

–Green LED labeled AC—When the power module is fully seated in its bay and is receiving source power within the required range, this LED should be on. It indicates that AC power is present and is within specified limits. The power supply fan should also be on.

–Green LED labeled DC—Power supply is operating normally in a powered-on condition.

•For a router equipped with DC-input PEMs:

–Green LED labeled INPUT OK—When the power module is fully seated in its bay and is receiving source power within the required range, this LED should be on. It indicates that DC power is present and is within specified limits. The power supply fan should also be on.

–Green LED labeled OUTPUT OK—DC-input PEM is operating normally in a powered-on condition.

–Amber LED labeled MISWIRE—Should be off. When it is on, it indicates that the input is wired backward at the PDU input.

Step 3 Go to the rear of the chassis and visually check the two LEDs on the front of the blower module. They should appear as described below:

•Green LED labeled OK—Should be on

•Red LED labeled FAIL—Should be off

Step 4 Listen for the blowers in the blower module; you should immediately hear them operating.

---

Note In a noisy environment, the blowers might be difficult to hear; in that case, place your hand in front of the exhaust vents at the rear of the chassis to verify that the blowers are operating.

2	CSC status LEDs (two)	5	Major alarm LED
3	SFC status LEDs (three)	6	Minor alarm LED

Step 5 Visually check the LEDs on the two alarm cards. (See Figure 3-21.) When the system is operating correctly, the following LED conditions should be true.

LEDs that normally should be off:

•One MBUS status LED labeled FAIL

•Two CSC status LEDs labeled FAIL

•Three SFC status LEDs labeled FAIL

•Three router alarm LEDs labeled CRITICAL, MAJOR, MINOR

LEDs that normally should be on:

•One MBUS status LED labeled ENABLED

•Two CSC status LEDs labeled ENABLED

•Three SFC status LEDs labeled ENABLED

Step 6 On the console terminal, verify that the console displays the system banner and that the system and all interfaces initialize successfully.

---

If the power modules do not power up, or if the system or any interfaces do not initialize properly, see Chapter 4, "Troubleshooting the Installation." If you are still unable to resolve the problem, contact your Cisco service representative for assistance.
