Step 4 Connect the other end of the power cord to an AC-input power source.
Step 5 Verify power supply operation by checking that the power supply LED is green.
Step 6 If the LEDs indicate a power problem, see LED Indicators section for troubleshooting information.
Step 7 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.
