Warning Indications
Warnings alert you to conditions that indicate possible service impact. Warnings are
displayed in the Messages pane in orange lettering.
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.
Before addressing warnings, ensure that all faults are resolved. Take appropriate
action to resolve the warnings, as indicated in the following tables.
Main Hub Warnings
{RF18}Potential failure in the UL RF path
Unable to complete the system end-to-end. Replace the RAU when possible.
{RF19}Potential failure in the DL RF path
Unable to complete the system end-to-end test. Check the RAU termination at
the SMA connector and re-test it. Replace the RAU if there are no Hub alarms.
{RF20}No communications with the
EH/Accel Hub
Check the CAT-5E/6 cable for shorts/opens, especially on new installations.
Check the CAT-5 Extender, if present. If the fault is common to more than one
RAU, replace the EH/Accel Hub. Try another port. If no fault is reported, flag
the previous port as unusable and replace the Hub when possible. Otherwise,
replace the RAU.
{RF21}The DL RF path loss is above the
recommended limit
Check the CAT-5E/6 cable for shorts/opens, especially on new installations.
Check the CAT-5 Extender, if present. If the fault is common to more than one
RAU, replace the EH/Accel Hub. Try another port. If no fault is reported, flag
the previous port as unusable and replace the Hub when possible. Otherwise,
replace the RAU.
{RF22}Frequency band not programmed
Use AdminManager to check band support in the RAU. Cycle power once. If
the fault persists, replace the RAU.
{RF23}Commanded Out-of-Service
Command In-Service to restore service.
{RF24}External fault lockout
Check the Hubs for faults. The RAU is out of service on command from the
Hub.
{RF25}Internal fault lockout
Check RAU faults. The RAU is out of service.
