the power supply bay.
Step 1
Step 2
Step 3
If the power supply fails to operate properly after several attempts to power it up, contact a service
representative for assistance.
Turning the power supply switch to ON (|) engages a latch that secures the power supply in
Check the following components to make sure they are secure:
•
Each power supply is inserted all the way into its bay, and the captive jackscrew is
tightened.
•
Any unused power supply bay slots have power supply blanks installed.
•
All source DC power cables are securely attached to the power supply threaded
terminals.
•
At the DC power-source end of the power cable, the cable is securely attached to the
source DC circuit breaker.
•
The source DC voltage is within the range indicated on the power supply faceplate.
•
When two supplies are installed, each power cable must be connected to a separate
60-amp DC service.
Verify that the Cisco 12012 powers up correctly. Visually check that the power supply
input OK LED goes on and stays on.
Visually check that the power supply output fail LED flashes on and off for five seconds,
then goes off.
•
If this output fail LED remains on, suspect a power supply failure or an adverse
environmental condition (the power supply has detected an overvoltage or
overtemperature condition and has shut down).
•
If two power supplies are installed, and the output fail LED goes on only on one power
supply, assume that the power supply or DC source (for that power supply) is faulty.
•
If the output fail LED lights on two power supplies that are connected separate DC
sources, assume that an overvoltage or overtemperature condition is causing the power
supplies to fail.
