The Sun Storage F5100 Flash Array has a total of six fan modules. Four fan modules labeled FM0 to FM3 are mounted to the fan board that is farthest from the front of the chassis (FANBD1). Two fan modules labeled FM1 and FM2 are mounted to FANBD0.
When a fan module fails and needs to be replaced, the amber Fault LED on the front panel and a fault indicator on the fan board, just below the faulted fan module will illuminate. In addition, the amber Temperature Fault LED might also illuminate.
All fan modules must be removed to access the connector board.
