Use the following procedure to troubleshoot the AC power shelf if it does not
operate properly after installation.
Make sure that the power shelf is seated properly:
The jackscrew is tightened securely.
•
The captive screws on the flanges are tightened securely.
•
Make sure each power supply is seated properly:
The ejector lever is locked into place by its spring clip.
•
Make sure the router is powered on and that all power cords are connected
properly:
Power cords on the back panel of the power shelf are secured in place with
•
their retention clips.
Power cords at the power source end are securely plugged into its own AC
•
power outlet.
Make sure the source AC circuit breaker is switched on.
•
Check the power supply status indicators:
PWR OK (green)—Indicates that the power supply is operating normally, and
•
the source AC voltage is within the nominal operating range of 200 VAC to
240 VAC. When the power supply is properly seated, this indicator is on.
FAULT (yellow)—Indicates that the system has detected a fault within the
•
power supply or the incoming voltage is too low. During normal operation,
this indicator remains off.
If the indicator is on:
– Check that the source voltage is within the correct range: 170 to 262 VAC
Remove and then apply power to the power supply by disconnecting its
–
power cord. If the indicator remains on, replace the existing power supply
with a spare.
If the spare power supply also fails, the problem could be a faulty power
–
shelf backplane connector. Power off the router and contact a Cisco
service representative for assistance.
