Cmod Population Rules - Oracle X5-8 Service Manual

CPU Module (CMOD) Overview
In both CMOD configurations, the system includes four power supplies, eight fan modules,
and eight DPCCs. However, fan modules and DPCCs receive power from the CMODs, so in a
four-CPU configuration, only fan modules 0-3 and DPCCs 0-3 are active. Fan modules 4-7 and
DPCCs 4-7 are not powered and not active.

CMOD Population Rules

The Oracle Server X5-8 supports four and eight CMOD configurations. Each CMOD supports a
single socket containing a single Intel EX Xeon E7-8895 v3 processor.
For the four-socket server configuration:
CPU modules (CMODs) must be installed in slots 0-3.
■
DPCC slots 0-3 are active; however DPCCs 4-7 must be installed.
■
Both fan frames must be installed.
■
All eight fan modules (FMs) must be installed but only FMs 0-3 are active.
■
For the eight-socket server configuration:
