Installing and Removing DIMMs

To remove or install the DIMMs, remove the Memory Board from the chassis and install the DIMMs

on the Memory Board, then reinstall the Memory Board. Be sure to follow the “Rules for Adding

Memory”.

CAUTION

Do not attempt to hot remove or hot add a Memory Board in a non-redundant configuration. If your

server is not configured in the BIOS setup utility for Maximum Compatibility, Memory RAID, or Memory

Mirroring, you must power down your server before removing or installing any Memory Board or

memory DIMMs. For instructions, see “Cold Removal of Memory Board” and “Cold Insertion of a

Memory Board”.

Rules for Adding Memory

The following rules apply when adding memory to the Memory Boards:

• DIMMs must be populated in pairs, referred to as a bank. The two banks of DIMMs are

defined on each Memory Board as:

- Bank 1: DIMM connectors 1A and 1B

- Bank 2: DIMM connectors 2A and 2B

• Within a single bank, both DIMMs must be identical. (Identical DIMM size and identical

number of devices on the DIMM.

• The system does not support mixed-sized DIMMs or DIMMs from different vendors within the

same bank.

• If installing a single bank of DIMMs on the memory board, install in Bank 1.

• If installing both a bank of single- ranked DIMMs and a bank of dual ranked DIMMs on the

same Memory Board, install the double-sided DIMMs in Bank 1 and the single sided DIMMs in

Bank 2.

• For best performance, use identical memory DIMMs on each Memory Board.

• Use only DDR2 DIMMs. Other DIMMs will not fit into the socket. Attempts to force a non-

DDR2 DIMM into a socket will damage either the socket or the DIMM.
