Insert the power cord plug into an external AC
power source receptacle.
Connect the power cord to the power supply.
Route the power cord along the cable restraint
towards the left or right corner of the chassis. If needed to hold
the power cord in place, thread plastic cable ties, which you must
provide, through the openings on the cable restraint.
Verify that the power cord does not block the air
exhaust and access to services gateway components, or drape where people
could trip on it.
Switch the AC switch on the each power
supply to the on position (—) and observe the status
LEDs on the power supply faceplate. If the power supply is correctly
installed and functioning normally, the AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit.
