Abstract
This invention relates to a visual indication system for a field replaceable unit. The system includes two or more visual indicators on a face of the field replaceable unit (FRU), each indicator having a unique shape and being switchable between an on state and an off state. Diagnostic and administrative control within the FRU functions to monitor overall operation of the FRU and, under the control of Network Operations Systems, selectively turns on or off the visual indicators to reflect status of the FRU.
