Interpret controller module LEDs

There are two redundant controller modules (CMs) that use a series of LEDs to reflect host connectivity status. You can
monitor the LEDs from the rear panel area to determine system status in combination with the user interface content. You
cannot mix controller types when daisy-chaining controllers.
In the case of a fault condition, identified in the state column with an asterisk (*), troubleshoot the fault and take appropriate
corrective action.
