SMP Expansion Module
The SMP Expansion Module contains the XceL4
™
system cache, DIMMs,
microprocessors, and voltage regulator modules (VRMs) needed to run the server.
This section contains the information needed to install and remove the SMP
Expansion Module, microprocessors, VRMs, and DIMMs.
SMP Expansion Module considerations:
v Use two hands to install or remove an SMP Expansion Module. Do not allow the
expansion module to come in contact with any of the boards, especially the
centerplane, while lifting it out or putting it into the server.
v For the server to operate properly, there must be a minimum of one SMP
Expansion Module and one SMP baffle installed.
v An SMP Expansion Module must contain at least one microprocessor and four
DIMMs.
v If it becomes necessary to remove or install DIMMs do so through the DIMM
access doors on the SMP Expansion Module. Refer to “DIMM removal and
replacement” on page 93 for the location of the DIMM access doors.
v
Before removing or installing SMP Expansion Modules you must remove the
electromagnetic compatibility (EMC) shield and SMP Expansion cables from the
rear of the server.
v You must run the Configuration/Setup Utility whenever you remove or replace a
SMP Expansion Module or one of its associated options.
