Use the information in this chapter to determine whether a problem originates with the hardware or the software. For further assistance, contact your Cisco customer service representative.

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, fans, and memory. 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, page 1-3). If the status is yellow, check for alarms
	using the show alarms command.
Step 3	Power down the appliance and all external devices.
Step 4	Check all cables and power cords. (See the “Checking Connections and Switches” section on page 6-2.)
