Removing a hot-swap power supply

Important: If the server has two power supplies, and if you remove either of them,
the server will not have redundant power; if the server power load then exceeds
675 W, the server might not start or might not function correctly.
To remove a power supply, complete the following steps.
4. If PCI riser-card assembly 1 contains one or more adapters, remove riser-card
assembly 1 (see "Removing a PCI riser-card assembly" on page 42).
5. Remove the DIMM air baffle (see "Removing the DIMM air baffle" on page 52).
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
6. Open the retaining clip 2 on each end of the DIMM connector.
7. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the server. Then, remove the DIMM from the package.
8. Turn the DIMM so that the DIMM keys align correctly with the connector.
9. Insert the DIMM into the connector 1 by aligning the edges of the DIMM with
the slots at the ends of the DIMM connector. Firmly press the DIMM straight
down into the connector by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the
DIMM is firmly seated in the connector.
Important: If there is a gap between the DIMM and the retaining clips, the
DIMM has not been correctly inserted; open the retaining clips, remove the
DIMM, and then reinsert it.
