Figure 57. DIMM installation
Step 6.
Touch the static-protective package that contains the DIMM to any unpainted metal surface on the
outside of the server. Then, remove the DIMM from the package.
Step 7.
Turn the DIMM so that the alignment slot align correctly with the alignment tab.
Step 8.
Insert the DIMM into the connector by aligning the edges of the DIMM with the slots at the ends of
the DIMM connector.
Step 9.
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.
Note: 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.
Step 10. Replace the air baffle (see "Replacing the air baffle" on page 109).
Note: Close all the retaining clips even for slots without DIMMs installed before replacing the
air baffle.
Step 11. Replace the cover (see "Installing the compute node cover" on page 107).
Step 12. Reconnect the power cords and any cables that you removed.
Step 13. Turn on the peripheral devices and the server.
Removing the optional 3.5-inch hard disk drive hardware RAID cage
Use this information to remove the optional 3.5-inch hard disk drive hardware RAID cage.
Before you remove the optional 3.5-inch hard disk drive hardware RAID cage, complete the following steps:
1. Read "Safety" on page v and "Installation guidelines" on page 89.
2. If the compute node is installed in an IBM NeXtScale n1200 Enclosure, remove it (see "Removing a
compute node from a chassis" on page 92 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
