Troubleshooting the Cisco 2524

and Cisco 2525 Routers

This appendix describes how to troubleshoot the Cisco 2524 and Cisco 2525 routers by

referring to the LEDs on the rear panel of the chassis (see Figure 1-2 and Figure 1-3) and

on the network processor modules (see Figure 1-4 through Figure 1-9).

The LEDs indicate the current operating condition of your router. You can observe the

LEDs, note any fault condition that the router is encountering, and then contact your system

administrator or a customer service representative, if necessary. Table B-1 describes the

LEDs on the router chassis and WAN modules.
