PRELIMINARY Fault Indications
10.2.1 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 the AdminManager. Start with the Main 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.
