Troubleshooting
c. Power cycle the Fusion Main Hub.
d. RAU hardware faults. Try moving a working CATV to the suspect port and
verifying that the RAU comes up OK.
e. Try isolating the system components:
– Check to see if the whole system is effected or a portion of the system.
– If the whole system is effected, disconnect the DAS system from the RF
source and see if the RF source is working.
– Continue to isolate by disabling portions of the system. Under System Con-
figuration, click
SHOW SYSTEM TREE and select a component. Then click SET

9.3.1.2 Fault/Warning/Status Indications
Once all of the units are powered on and the cable connections are made, the faults
from each unit can be requested using AdminBrowser. Start with the Fusion 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.
NOTE: If you have a red STATUS LED without a fault message, it probably
indicates that the unit is locked out.
Refer to Appendix C for tables containing Fault, Warning, and Status messages and
their meanings.
9.3.2 Troubleshooting Using LEDs
The following troubleshooting guide is from the perspective that all Fusion equip-
ment is installed, their cables are connected, and they are powered on; it is assumed
that the system was operating normally before the problem to be diagnosed occurred.
Always use AdminBrowser, if possible, to troubleshoot the system. The Fusion Main
Hub and Expansion Hub LEDs are for backup troubleshooting. The RAU LEDs prob-
ably will not provide additional information for troubleshooting.
