Check for the following before connecting the power cords:
Make sure that all of the power supplies are seated firmly,
with the captive screws tightened.
Make sure that all of the ON/OFF switches on the power
supplies are OFF.
If you are using multiple power supplies to ensure fault
tolerance, make sure that there is a dedicated power circuit
available for each supply. The separate power sources help
ensure operation when the power source itself fails.
To connect the power supplies:
1. Plug the power cord into each power supply.
2. Plug the power cord into an AC outlet.
* Note: Refer to the DC power supply documentation if
you are installing DC power supplies.
To power on the system:
1. Check all power connections.
2. Turn on each power supply by switching on the power
switches on each supply.
As the system powers on:

as the system continues through its power-on diagnostics, if
the modules operate properly.
