Installing, removing, or replacing optional hardware devices

This section provides instructions on how to install, remove, or replace optional

hardware devices for your server. You can expand the capabilities of your server

by adding memory modules, PCI cards, or drives, and maintain your server by

replacing the failing optional hardware devices. If you are replacing an optional

hardware device, perform the removal procedure and then perform the installation

procedure for the optional hardware device you want to replace.

Memory module installation rules

Your server has eight memory slots for installing or replacing DDR3 SDRAM

DIMMs that provide up to a maximum of 64 GB of system memory.

The following tables provide information about the memory module installation

rules that you should consider when installing a memory module. The “X” mark

indicates the suggested memory slot(s) into which the memory module(s) should

be installed in different situations. The number, for example 1, 2, or 3, indicates the

installation sequence. See “Locating parts on the system board” on page 32 to

identify the various memory slots.

Note: All memory module types and capacities must be consistent.

Note: Installing DIMMs on channel A and channel B of CPU0 should enable Channel

Mirroring Mode. This mode requires that you install the DIMMs in pair, and the DIMM

installation for Channel Mirroring Mode is one DIMM on CPU0 DIMM CHA0 and one

DIMM on CPU0 DIMM CHB0 when a single microprocessor (CPU0) is installed.
