11. If you are installing a high-capacity power supply, move the AC input switch on the faceplate of the
power supply itself to the on (1) position.
12. Verify the following LED indications for each installed power supply:
•
For standard-capacity AC power supplies, verify that the AC OK and DC OK LEDs light steadily and
the PS FAIL LED is not lit.
•
For high-capacity AC power supplies, verify that the DC OK LED lights steadily and the PS FAIL LED
is not lit. In addition, the AC-1 OK LED should light green steadily if the upper AC feed (on the chassis
above the power supply) is connected and receiving power, and the AC-2 OK LED should light green
steadily if the lower AC feed (on the power supply itself) is connected and receiving power.
NOTE: After a power supply is powered on, it can take up to 60 seconds for status
indicators—such as the status LEDs on the power supply and the show chassis command
display—to indicate that the power supply is functioning normally. Ignore error indicators
that appear during the first 60 seconds.
If any of the status LEDs indicates that the power supply is not functioning normally, repeat the
installation and cabling procedures.
