10.4 System Fan Connectors
The server board is capable of supporting up to a total of six system fans. Each system fan includes a pair of
fan connectors; a 1x10 pin connector to support a dual rotor cabled fan, typically used in 1U system
configurations, and a 2x3 pin connector to support a single rotor hot swap fan assembly, typically used in 2U
system configurations. Concurrent use of both fan connector types for any given system fan pair is not
supported.

Each connector is monitored and controlled by on-board platform management. On the server board, each
system fan connector pair is labeled “SYS_FAN #”, where # = 1 – 6. The following illustration shows the
location of each system fan connector on the server board.
