Chapter 5 Troubleshooting the System Hardware

Undetermined Problems

Check the LEDs on all the power supplies. If the LEDs indicate the power supplies are working correctly, follow these steps:

Step 1 Power down the device.

Step 2 Be sure the device is cabled correctly.

Step 3 Remove or disconnect the following devices (one at a time) until you find the failure (power up the device and reconfigure it each time):

Any external devices

Surge suppressor device (on the device)

Modem, printer, mouse, or non-Cisco devices

Each adapter

Disk drives

Memory modules (minimum requirement = 256 MB [two banks of 128-MB DIMMs])

Note Any component that is internal to the device, with the exception of customer-replaceable adapters, must be serviced by a licensed service technician. Contact your service representative.

Step 4 Power up the device. If the problem remains, suspect the following parts in the order listed:

a.Power supply

b.Power cage assembly

c.System board

Note If the problem goes away when you remove an adapter from the system, and replacing that adapter does not correct the problem, suspect the system board.
