Removing an AC-Input Power Supply

Warning
Voltage is present on the backplane when the system is operating. To reduce
risk of an electric shock, keep hands and fingers out of the power supply
bays and backplane areas.
Follow these steps to remove an AC-input power supply:
Step 1 Turn the power switch to the Off (0) position on the power supply you are
removing. (See Figure 5-1.) Turning the power switch to the Off (0) position also
disengages a pawl that unlocks the power supply from the chassis.
Step 2 Disconnect the power cord from the power source.
