Server Subsystems
■
All CMOD processors have a heat sink.
■
Each drive bay contains a storage device or a drive slot filler.
■
Every DPCC is installed (regardless of whether it contains a card or not).
■
Both fan frames are populated with fan modules.
Cooling Zones
The server has five cooling zones. The cooling zones are designated from left to right (from the
front of the server) as zone 0 - zone 4. The airflow cooling in zone 0 is concentrated through the
power supplies (PSUs) and is provided by the internal PSU fan modules.
The fan modules (FMs) provide the airflow cooling for zones 1-4. Each zone has a pair of
dedicated FMs:
■
Zone 1 airflow cooling is concentrated on the CPU modules (CMODs) 0 and 1 and is
provided by FMs 0 and 1.
■
Zone 2 airflow cooling is concentrated on CMODs 2 and 3 and is provided by FMs 2 and 3.
■
Zone 3 airflow cooling is concentrated on CMODs 4 and 5 and is provided by FMs 4 and 5.
■
Zone 4 airflow is concentrated on CMODs 6 and 7 and is provided by FMs 6 and 7.
Note -
In a four-CMOD configured server, the fan modules for cooling zones 3 and 4 are
not powered. However, to maintain the integrity of the cooling subsystem, FMs 4-7 must be
installed in the server.
