4.2 Internal Disk Drive and Fan LEDs

The array includes internal LEDs on the disk drives and the fan modules.


Note - On fan modules, the green and amber (OK and Fault) LEDs might be on simultaneously. This indicates that one of the fans in the module has failed, the other fan is still operational.


Disk Drive and Fan Tray LEDs (Fans located at the front of the enclosure) shows the location of the internal LEDs and a close-up view of the disk drive and fan trays, including the symbols that identify the LEDs. Internal LEDs lists the internal LEDs.
