Removing an AC power supply

The procedures for removing an AC power supply differ depending on the power
supply type (replacement or original). Be sure to refer to the appropriate procedures
in this section. For the differences between replacement and original power
supplies, see "About replacement power supplies" on page 21.
CAUTION:
The power supplies are hot swappable, which means they can be removed
and replaced while the chassis is powered on and running. However, IBM
recommends that you disconnect the power supply from the wall outlet
before removing and replacing the supply. The chassis can be running while
a power supply is being removed and replaced, but the power supply itself
should not be connected to a power source. Otherwise, you could be injured
or the power supply or other parts of the device could be damaged.
Note: Disabling or removing a POE power supply also disables the POE daughter

Removing a replacement power supply

To remove a replacement AC power supply, you need a Phillips-head or a flathead
screwdriver.
