Maintaining the Cisco Catalyst 5500 Multiswitch

Router

This chapter contains recommended hardware maintenance procedures for the Cisco Catalyst 5500

Multiswitch Routers (MSRs), which provide an Ethernet backbone for connections between the

Cisco Signaling Link Terminals (SLTs), Cisco Media Gateway Controllers (MGCs), and Cisco Media

Gateways (MGWs). You can configure several virtual LANs (VLANs) on the Catalyst 5500s and the

route switch modules (RSMs) provide inter-VLAN routing when necessary. If your solution includes

two Catalyst 5500s, they are connected through an Inter-Switch Link (ISL) trunk, enabling them to share

VLAN data and provide ensured availability.

This chapter describes hardware maintenance; for information on upgrading and maintaining

Catalyst 5500 software, refer to the Cisco Media Gateway Controller Software Release 7 Installation

and Configuration Guide.

This chapter includes the following sections:

Replacing Hardware Components

Avoiding Problems When Inserting and Removing Modules

The ejector levers on the supervisor engine and switching modules align and seat the module connectors

in the backplane (see Figure 7-5). Failure to use the ejector levers to insert the module can disrupt the

order in which the pins make contact with the backplane. Follow the installation and removal instructions

carefully.

When removing a module, use the ejector levers to ensure that the module connector pins disconnect

from the backplane properly. Any supervisor engine or switching module that is only partially connected

to the backplane can disrupt the system. Detailed instructions for removing and installing switching

modules are described in the Catalyst 5000 Series Module Installation Guide.

Figure 7-5 Ejector Levers and Captive Installation Screws (Supervisor Engine II Shown)

Tools Required

Use a flat-blade screwdriver to remove any filler (blank) modules and to tighten the captive installation

screws that secure the modules in their slots. When you handle modules, use an ESD-preventive wrist

strap or other grounding device to prevent electrostatic discharge (ESD) damage.

Removing the Supervisor Engine

Before you remove a supervisor engine, you should first upload the current configuration to a server.

This saves time when bringing the module back online. You can recover the configuration by

downloading it from the server to the nonvolatile memory of the supervisor engine.

To remove a supervisor engine, perform the following steps:

Step 1 If you do not plan to immediately reinstall the supervisor engine you are removing, disconnect any

network interface cables attached to the module ports.

Step 2 Use a screwdriver to loosen the captive installation screws at the left and right sides of the module.

Step 3 Grasp the left and right ejector levers and simultaneously pull the left lever to the left and the right lever

to the right to release the module from the backplane connector.

Step 4 Grasp the handle of the module with one hand and place your other hand under the carrier to support and

guide the module out of the slot. Avoid touching the module.

Step 5 Carefully pull the module straight out of the slot, keeping your other hand under the carrier to guide it.

Keep the module at a 90-degree orientation to the backplane.

Step 6 Place the removed module on an antistatic mat or antistatic foam.

Step 7 If the slot is to remain empty, install a module filler plate to keep dust out of the chassis and to maintain

proper airflow through the module compartment.

Caution Always install a switching module filler plate in empty switching module slots to maintain the proper

flow of cooling air across the modules.

Note When you remove and replace the supervisor engine, the system provides status messages on the console

screen. The messages are for information only. Enter the show system and show module commands to

view specific information. For additional information, refer to the Catalyst 5000 Series Software

Configuration Guide and the Catalyst 5000 Series Command Reference. Also, refer to the Preface for a

description of Cisco Connection Online (CCO).

Replacing the Supervisor Engine

To replace the supervisor engine, perform the following steps. Note that the supervisor engine must go

in slot 1 and the redundant supervisor engine in slot 2.

Step 1 Remove the module filler plate, if any.

Step 2 Grasp the handle of the module with one hand and carefully align the module with the slot, keeping your

other hand under the carrier to support it. Keep the module at a 90-degree orientation to the backplane.

Step 3 Carefully push the module straight into the slot, keeping one hand under the carrier to guide it. Avoid

touching the module.

Step 4 Make sure that the ejector levers are pushed in, holding the module to the backplane connector.

Step 5 Use a screwdriver to tighten the captive installation screws at the left and right sides of the module.

Step 6 Reattach network interface cables to the module ports.

Using Flash Memory (PCMCIA) Cards (Supervisor Engine III)

The Flash memory (PCMCIA) card slots on the front panel of Supervisor Engine III are for additional

PCMCIA-based Flash memory. You can use this Flash memory to store and run Cisco IOS images, or to

serve as an I/O device. Occasionally, it might be necessary to remove and replace Flash memory cards;

however, removing Flash memory cards is not required and is not recommended after the cards are

installed in the slots.

Supervisor Engine III has two PCMCIA slots: slot 0 (bottom) and slot 1 (top). The following procedure

is generic and can be used for a Flash memory card in either slot position.

Chapter 7 Maintaining the Cisco Catalyst 5500 Multiswitch Router

Replacing Hardware Components

Note You can insert and remove the Flash memory card with the power on.

Before you install a card, verify that the Flash memory card is set with write protection off. The

write-protect switch is located on the front edge of the card when oriented with the printing right side

up and the edge connector end away from you. (See Figure 7-6.)

Figure 7-6 Locating the Flash Memory Card Write-Protection Switch

Use the following procedure for installing and removing a Flash memory card:

Step 1 Face the front panel of the switch and hold the Flash memory card with the connector end of the card

toward the slot. The connector end of the card is opposite the end with the write-protection switch, which

is shown in Figure 7-6.

Step 2 Insert the card into the appropriate slot until the card completely seats in the connector at the back of the

slot and the eject button pops out toward you. Note that the card does not insert all the way into the slot;

a portion of the card remains outside the slot. Do not attempt to force the card past this point.

Step 3 To eject a card, press the appropriate ejector button until the card is free of the connector at the back of

the slot.

Step 4 Remove the card from the slot and place it in an antistatic bag.
