Faults Reported by the RAU
Alarm Message
Action
{RF01}Software error occurred and recov-
ered
If this happens repeatedly, replace the RAU. (Log entry only.)
{RF02}Software error occurred and recov-
ered
If this happens repeatedly, replace the RAU. (Log entry only.)
{RF03}Software error occurred and recov-
ered
If this happens repeatedly, replace the RAU. (Log entry only.)
{RF04}Software reset occurred and recov-
ered
If this happens repeatedly, replace the RAU. (Log entry only.)
{RF05}Software error occurred and recov-
ered
If this happens repeatedly, replace the RAU. (Log entry only.)
{RF06}Hardware failure (SPI)
Cycle power once. If fault persists, replace the RAU
{RF09}Temperature is too high
Check for proper installation. Check environmental controls, move RAU to
cooler environment.
{RF10}DC Power supplied by the
EH/Fusion SingleStar Hub is too low
If the fault is common to more than one RAU, replace the Fusion SingleStar
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.
{RF11}DC Power supplied by the
EH/Fusion SingleStar Hub is too high
If the fault is common to more than one RAU, replace the Fusion SingleStar
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.
{RF12}Hardware failure (PA)
Replace the RAU.
{RF13}Hardware failure (PA)
Replace the RAU.
{RF14}Hardware failure (PLL Unlock)
If the fault is common to more than one RAU, replace the Fusion SingleStar
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.
{RF15}The DL RF path loss is too high
If the fault is common to more than one RAU, replace the Fusion SingleStar
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.
{RF16} The DL RF path operating at mini-
mum gain
Check the CATV cable loss, especially on new installations. Validate that mini-
mum cable length requirements are met. If the fault is common to more than
one RAU, replace the Expansion/Fusion SingleStar Hub when possible. Try
another port. If no fault is reported, flag the previous port as unusable and
replace the Hub when possible. Otherwise, replace the RAU when possible.
{RF17}Hardware failure
Replace the RAU.
{RF18}Potential failure in the UL RF path
Unable to complete system end-to-end. Replace the RAU when possible.
{RF19}Potential failure in the DL RF path
Unable to complete system end-to-end test. Check RAU termination at THE
SMA connector and re-test. Replace the RAU if there are no Hub alarms.
