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:

• Checking Equipment Status, page 7-1

• Replacing Hardware Components, page 7-5

Checking Equipment Status

Check the status of the Cisco Catalyst 5500, using the following methods:

• Reading the Cisco Catalyst 5500 LEDs

• Querying the status using the Catalyst command line interface (CLI)

• Querying the system using CiscoWorks 2000 and Cisco WAN Manager (CWM)

Cisco Catalyst 5500 LEDs

LEDs of the Catalyst 5500 may vary, depending on which components are installed. The LEDs described in this section are factory default.

Replacing Hardware Components

Using the Command Line Interface to Check Status

The Cisco Catalyst 5500 command line interface includes a series of commands that enable you to determine if the MSR is functioning correctly or where problems have occurred. Relevant commands for checking status include ping, traceroute, test snmp trap, and show. There are more than 100 show commands, many of which can be used to check status. To learn how to find more information concerning these and other commands, refer to the Command Reference Manual that came with the Cisco Catalyst 5500 MSR.

Replacing Hardware Components

This section describes how to perform the following removal and replacement procedures for Cisco Catalyst 5000 series field-replaceable units (FRUs):

• Removing the Supervisor Engine, page 7-6

• Using Flash Memory (PCMCIA) Cards (Supervisor Engine III), page 7-7

• Removing and Replacing the Power Supply, page 7-8

• Removing and Replacing the Chassis Fan Assembly, page 7-15

For instructions on installing and replacing switching modules, refer to the Catalyst 5000 Series Module Installation Guide.

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.

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.
