To install a DIMM, complete the following steps.
1. Open the retaining clip on each end of the DIMM connector.
2. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the server. Then, remove the DIMM from the package.
3. Turn the DIMM so that the DIMM keys align correctly with the connector.
4. Insert the DIMM into the connector 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. 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.
5. Repeat steps 1 through 4 until all the new or replacement DIMMs are installed.
6. Replace the air baffle over the DIMMs (see “Installing the DIMM air baffle” on
page 96).
7. Replace the riser-card assembly (see “Installing the riser-card assembly” on
page 98).
8. Install the cover (see “Installing the cover” on page 91).
9. Slide the server into the rack.
10. Reconnect the external cables; then, reconnect the power cords and turn on
the peripheral devices and the server.
Removing a hot-swap fan
Attention: To ensure proper server operation and cooling, if you remove a fan
you must install a replacement fan as soon as possible.
