Troubleshooting the Installation

This chapter contains general troubleshooting information to help isolate the cause of any difficulties

you might encounter during the installation and initial startup of the system.

Although an over-temperature condition is unlikely at initial startup, environmental monitoring

functions are included in this chapter because these too monitor internal voltages.

Troubleshooting the installation is presented in these sections:

•Troubleshooting Overview, page 4-1

•Troubleshooting the Power Subsystem, page 4-3

•Troubleshooting the Route Processor Subsystem, page 4-9

•Troubleshooting the Line Card, page 4-12

•Troubleshooting the Cooling Subsystem, page 4-18

Troubleshooting Overview

This section describes the methods used in troubleshooting the router. The troubleshooting methods are

organized according to the major subsystems in the router.

If you are unable to solve a problem on your own, you can contact a Cisco customer service

representative for assistance. When you call, have this information ready:

•Date you received the router and the chassis serial number (located on a label on the back of the

chassis).

•Installed line card and Cisco software release number:

–

Use the show version command to determine the Cisco software release number.

•Brief description of the symptoms and steps you have taken to isolate and solve the issue.

•Maintenance agreement or warranty information.

Troubleshooting Using a Subsystem Approach

To solve a system problem, try to isolate the problem to a specific subsystem. Compare the current router

behavior with the expected router behavior. Because a startup issue is usually attributable to one

component, it is most efficient to examine each subsystem, rather than trying to troubleshoot each router

component.
