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 error 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 the power once. If the fault persists, replace the RAU
{RF09}Temperature is too high
Check for proper installation. Check environmental controls, move the RAU to
a cooler environment.
{RF10}DC Power supplied by the
EH/Accel Hub is too low
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.
{RF11}DC Power supplied by the
EH/Accel Hub is too high
Check the CAT-5E/6 cable for shorts/opens, especially on new installation.
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.
{RF12}Hardware failure (PA)
Replace the RAU.
{RF13}Hardware failure (PA)
Replace the RAU.
{RF14}Hardware failure (PLL Unlock)
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.
{RF15}The DL RF path loss is too high
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.
{RF16} DL RF path operating at minimum
gain
Check the CAT-5E/6 cable for shorts/opens, especially on new installations.
Check the CAT-5 Extender, if present, and validate that minimum cable length
requirements are met. 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.
{RF17}Hardware failure
Replace the RAU
