Use the information in this chapter to determine whether a problem originates with the hardware or the

Note When console redirection is enabled (it is disabled by default), all the tests available from a keyboard
are accessible through the console connection as well. (Mouse support, however, is not available through
the console connection.)
Caution Customer-replaceable components include the WAVE Interface Modules, hard disk drives, power supply
assemblies, and fans. All other components that are not orderable as spare hardware options can only be
replaced by a qualified service technician. Once you have identified a faulty component, contact the
Cisco Technical Assistance Center (TAC).
Identifying System Problems
To identify system problems, follow these steps:
Step 1 Check the power LED.
Step 2 Check the system fault LED (see System fault LED in Chapter 1, “Introducing the Cisco Wide Area
Virtualization Engine 7541, 7571, and 8541). If the status is yellow, check for alarms using the show
alarms command.
Step 3 Power down the appliance and all external devices.
