Main Hub, Expansion Hub, and RAUs have front-panel indicator
LEDs that provide diagnostic information and the operational status of each unit.
Together they provide an efficient diagnostic display system for maintenance and
fault location if a malfunction ever exists. The troubleshooting procedures in this
section are based on the front panel diagnostic LEDs.
The following table contains supplementary troubleshooting information that the
diagnostic LEDs do not cover. Please check the table for a possible cause of a
problem. Some simple checks or a minor adjustment might eliminate the problem
and restore proper operation.
