Figure 45 Port LEDs for SAS, fibre channel, iSCSI, and 10GBase-T iSCSI controller modules
Interpret SAS 12Gb/s expansion input/output module LEDs
Input/output modules (IOMs) in an expansion enclosure provide optional added storage. The IOM LEDs are
similar in function to controller module (CM) LEDs, reflecting host connectivity status and IOM fault conditions.
