DETAILED STEPS
Step 1
Remove the tape from the circuit-breaker switch handle, and restore power by moving the circuit-breaker switch handle
to the On (|) position.
Step 2
Verify power supply operation by checking if the power supply front panel LEDs are in the following states:

If you are installing 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.
If you are installing a redundant DC power supply, repeat these steps for the second power source.
