CAUTION:
Power supplies are easy to install and remove, but they are
not hot-swappable. Always disconnect all server power
cords and all power supply power cords before you remove
or install a power supply.
To remove a power supply, do the following steps:
1. Locate the cover on the power-supply bay (at the back of the
power-supply chassis).
2. Remove the four screws from the cover.
3. Remove the power-supply cover and save for future use.
