DETAILED STEPS
Step 1
Plug the power cord into the power supply.
Step 2
Connect the other end of the power cord to an AC input power source.
Step 3
Verify power supply operation by checking that the power supply LEDs are in the following states:
•
INPUT OK LED is green.
•
OUTPUT FAIL LED is green.
Step 4
If the LEDs indicate a power problem, see the Power Supply LEDs section. For troubleshooting information, see the
Cisco ASR 901 Series Aggregation Services Router Hardware Installation Guide.
Step 5
If you are installing a redundant power supply, repeat these steps for the second power source.
If you are installing a redundant AC power supply, ensure that each power supply is connected to a separate power source
in order to prevent power loss in the event of a power failure.
Removing and Replacing the AC Power Supply
The Cisco ASR 903 power supplies are hot-swappable. If you have installed redundant power supply
modules, you can replace a single power supply without interrupting power to the router.
Note
When you install the unit, the ground connection must always be made first and disconnected last. Statement
