If there is an RF14 Fault and the Cat-5/5E/6 run has an Extender, check that it
is installed correctly. See Section , “Installing a Cat-5 Extender,” on page
7-30.
f.
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

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 Main Hub and
work downstream.
NOTE:
AdminManager v2.04 or higher displays events (faults, warnings,
or status messages) depending on your view preference. To change your
view preference, refer to Section 3.4.2, “View Preference,” on page 3-10.
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.
Faults messages are displayed in the Messages pane in red lettering.
