• DIMM D1 and DIMM D2 need not be identical in organization, size and speed.
• Sparing should be enabled in BIOS setup. The BIOS configures Rank Sparing Mode.

{DIMM C2, DIMM D2} will be selected as the spare pair units.
3.4.3 Installing DIMMs
To reduce the risk of electrostatic discharge (ESD) damage to the processor:
• Touch the metal chassis before touching the DIMM or server board.
• Keep part of your body in contact with the metal chassis to dissipate the static charge while
handling the DIMM.
• Avoid unnecessary movement.
• Use a ground strap attached to the front panel (with the bezel removed.)
To install DIMMs, follow these steps:
1. Remove the chassis cover. For instructions, see Section 3.2.3, “Removing the Chassis Cover” on
page 26 .
2. Remove the processor air duct. For instructions, see Section 3.2.5, “Removing the Processor Air
Duct” on page 28 .
3. Locate the DIMM sockets on the server board. (See Figure 26 .)
4. Open both DIMM socket levers. (“A”)
5. Note the location of the alignment notch. (“B”)
6. Insert the DIMM making sure the connector edge of the DIMM aligns correctly with the socket.
(“E”)
7. Using both hands, push down firmly and evenly on both sides of the DIMM until it snaps into place
and the levers close. (“C” and “D”)
IMPORTANT: Visually check that each latch is fully closed and correctly engaged with notch on the
DIMM edge. (“E”)
8. Replace the air duct and chassis cover if you have completed all work inside of the server.
