Check the LEDs on all the power supplies. If the LEDs indicate the power
supplies are working correctly, follow these steps:
Step1 Power down the device.
Step2 Be sure the device is cabled correctly.
Step3 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.
Step4 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.
