LGCell Remote Access Unit Alarm
5.2 LGCell Remote Access Unit Alarm
The RAU communicates its status to the Expansion Hub over the Cat-5 cable. The
Expansion Hub, in turn, communicates the status to the Main Hub. The Main Hub’s
MMF port LEDs can be used to help troubleshoot downstream problems; however,
the LEDs do not indicate which downstream unit has the alarm.
