4.1.1 System Fan Board
A system fan board is used in systems configured to support fixed mount hard drives. The
system fan board is used to provide power to each system fan, and used as a communication
interconnect between each fan and the server board, allowing for server management to
monitor and manage each fan. The system fan board also includes a fan fault LED for each
system fan. The LED functionality is controlled by server management software. Should a
specific system fan fail, the matching fault LED will illuminate.
