Check the system LEDs for the power supplies (see the 

). If the LEDs indicate the power supplies are working correctly, follow these steps:

Power down the appliance.

Be sure the appliance is cabled correctly.

Remove or disconnect the following devices (one at a time) until you find the failure (power up the 
appliance and reconfigure it each time):

Any non-Cisco devices

Surge suppressor device (on the appliance)

Each Cisco Interface Module

Disk drives

Any component that is internal to the appliance must be serviced by trained and qualified 
personnel. Contact your customer service representative.

Power up the appliance. If the problem remains, contact Cisco TAC.

If the problem goes away when you remove a device from the system, and replacing that device 
does not correct the problem, contact Cisco TAC.

If you suspect a networking problem and all the system tests pass, check if there is a network 
cabling problem external to the system.

Because of the variety of hardware and software combinations that can be encountered, use the following 
information to assist you in identifying the problems. If possible, have this information available when 
requesting technical assistance.

Machine type and model

Failure symptom

What, when, where; single or multiple systems?

Is the failure repeatable?

Has this configuration ever worked?

If it has been working, what changes were made before it failed?

Is this the original reported failure?
