11. Connect the other end of the battery cable or flash power module cable to the
battery or flash power module.
12. Reinstall the retention clip to secure the battery or flash power module in
place.
If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 116.
Installing an additional microprocessor and heat sink
The following notes describe the type of microprocessor that the server supports
and other information that you must consider when you install a microprocessor
and heat sink:
v
Be extremely careful. The microprocessor socket contacts are very fragile.
v
The server base system board supports two microprocessors, and the optional
microprocessor and memory expansion tray provides two additional
microprocessor slots plus 24 additional DIMM connectors. The server supports
up to four Intel Xeon four-core, six-core, or eight-core microprocessors
(depending on your model) with the microprocessor and memory expansion
tray installed. To confirm that the server supports the microprocessor, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/ for a
list of supported microprocessors.
v
A microprocessor air baffle must be installed whenever the two DIMM
connectors closest to the microprocessor (on the left and the right) are empty.
For example, when DIMM connectors 6 and 7 on the system board are empty, a
microprocessor air baffle must be installed on microprocessor 1. This is
applicable for all microprocessors.
v
Microprocessors 3 and 4 must be installed as a pair on the optional
microprocessor and memory expansion tray.
Note: The server does not support a configuration of three microprocessors. You
must install one, two, or four microprocessors in the server.
v
Do not mix four-core, six-core, and eight-core microprocessors in the same
server.
v
The microprocessor options that IBM supports are limited by the capacity and
capability of the server. Any additional microprocessor that you install must
have the same specifications as the microprocessors that came with the server.
v
You must always have a microprocessor in socket 1 on the system board.
v
When one microprocessor is installed, the microprocessor air baffle, the DIMM
air baffle, or the microprocessor and memory expansion tray must be installed to
provide proper system cooling.
v
When you install an additional microprocessor, you must also install additional
memory. See “Non-mirroring (independent mode)” on page 44, “Memory
mirroring” on page 44, and “Memory sparing” on page 45 for details about
DIMM installation sequence.
v
To ensure proper server operation when you install an additional
microprocessor, use microprocessors that have the same QuickPath Interconnect
(QPI) link speed, integrated memory controller frequency, core frequency, power
segment, internal cache size, and type.
v
Installing microprocessors of different stepping levels within the same server is
supported.
