Cooling Zones
The server has five front-to-back cooling zones. The cooling zones are numbered from left to right (from the front of the server) as zone 0 to zone 4.
The airflow cooling in zone 0 is concentrated through the power supplies (PSs) and is provided by the internal PS fan modules.
The fan modules (FM0- FM7) provide the airflow for cooling zones 1-4. Each zone has a pair of dedicated FMs:
-
Zone 1 airflow cooling is concentrated on the CPU modules (CMODs) CMOD0 and CMOD1 and is provided by FM0 and FM1.
-
Zone 2 airflow cooling is concentrated on CMOD2 and CMOD3 and is provided by FM2 and FM3.
-
Zone 3 airflow cooling is concentrated on CMOD4 and CMOD5 and is provided by FM4 and FM5.
-
Zone 4 airflow is concentrated on CMOD6 and CMOD7 and is provided by FM6 and FM7.
