Remove and Replace the Power Supply
Redundant power supplies support online insertion and removal (OIR); if you remove one power supply, the
second power supply immediately ramps up to maintain uninterrupted operation. In this case, proceed to Step 2.
If you have only one power supply, you must turn off power before removing and replacing it. In this case,
proceed to Step 1.
Step 1
Turn off the power source.
Step 2
Turn off the switch on the power supply.
Step 3
Disconnect the power cable from the power source.
Step 4
Disconnect the power cable from the power supply.
For the AC-input power supply: Lift up the cable retention clip and remove the power cable from the
AC power receptacle.
