Activate a DC Power Supply Module
Perform the following procedure to activate a DC power supply:
Step 1
Remove the tape from the circuit-breaker router handle, and restore power by moving the circuit-breaker router handle
to the On (|) position.
Step 2
Verify power supply operation by checking if the respective power supply front panel LED (PS0 or PS1) is green.
Step 3
If the LEDs indicate a power problem, see
Troubleshooting
.
Step 4
If you are connecting a redundant DC power supply, repeat these steps for the second power source.
If you are connecting a redundant DC 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.
