Use the following procedure to troubleshoot the AC power supply if it is not
operating properly after installation.
Make sure the power supply is seated properly as follows:
Eject and reseat the PEM.
•
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 their own AC
•
power outlet.
The source AC circuit breaker is switched on.
•
Check the power supply status indicators:
PWR OK (green)—Indicates the power supply is operating normally, and the
•
source AC voltage is within the nominal operating range of 200 VAC to
240 VAC. This indicator lights when the power supply is properly seated in
position.
FAULT (yellow)—Indicates the system 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.
