Removing the 450-Watt Non-Redundant Power Supply

38
If the 450-Watt "non-redundant" power supply fails, you will need to replace it as soon as possible
to restore the server to operational status. See Figure 4-9 for an example view that also shows the
two rear screw locations on the supply.
Figure 4-9
450-Watt (Non-redundant) Power Supply Example
Use the following steps to remove the failed supply:
1. Remove the rear cover portion from the server chassis; see "Remove/Replace the Chassis
Top Covers" on page 18 if you are unfamiliar with the procedure.
2. Verify the power cord is disconnected from the unit, then confirm that the supply is cool
enough to touch.
3. Reach in and undo the small, medium and large power connector cables on the outer side of
the power supply, see Figure 4-10 on page 39. Note their locations for re-installation
purposes.
4. Undo the two Phillips-head screws on the rear of the chassis that hold the 450-Watt supply
rear case in place (shown in Figure 4-9).
5. Undo the single bracket screw near the fan at the "front" of the supply, shown in
Figure 4-10. Set all screws carefully aside for use during the re-installation process.
6. Lift the failed unit up and out of the server chassis. See the next subsection for installation of
a new power supply unit.
