8.3.1 Troubleshooting using AdminManager
To begin troubleshooting, use AdminManager software to determine the current
faults and warnings for all of the units in the system. To troubleshoot, start with the
Accel Hub’s faults and warnings, then proceed to each of the RAUs.
8.3.1.1 Fault Indications
Once all of the units are powered on and the cable connections are made, the faults
from each unit can be requested using AdminManager. Start with the Accel Hub and
work downstream.
Resolve all faults first and then check the warnings. Take appropriate action to
resolve the faults, as indicated in the following tables. In cases where there is more
than one possible cause, they are listed from the “most likely” to the “least likely”
cause. Actions are listed in the order that they should be performed; not all actions
may need to be done.
NOTE: If you have a red STATUS LED without a fault message, it probably
indicates that the unit is locked out.
