To remove a non-hot-swap power supply cage assembly, complete the following
steps.
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 95.
2. Turn off the server and all attached devices; then, disconnect all power cords
and external cables.
3. Unlock and remove the side cover (see “Removing the side cover” on page
100).
Note: It might be helpful to lay the server on its side for the remainder of this
procedure.
4. Disconnect the cables from the power supply to the system board and all
internal components.
Attention: Support the power supply while you remove the mounting screws.
After the screws are removed, the power supply is loose and can damage other
components in the server.
5. Lift up the power-supply cage handle and pull the power-supply cage assembly
all the way up until the retainer latch locks the cage in place on the chassis.
