{EF27} Port 3 UL RF path loss is too high
CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check Cat-5E/6 cable loss, especially on new install. Check Cat-5 Extender, if
present. If fault present on all EH ports, replace the EH. Otherwise, try another
EH port. If no fault is reported, flag the previous port as unusable and replace
the EH when possible. Otherwise, replace the RAU.
{EF28} Port 4 UL RF path loss is too high
CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check Cat-5E/6 cable loss, especially on new install. Check Cat-5 Extender, if
present. If fault present on all EH ports, replace the EH. Otherwise, try another
EH port. If no fault is reported, flag the previous port as unusable and replace
the EH when possible. Otherwise, replace the RAU.
{EF29} Port 5 UL RF path loss is too high
CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check Cat-5E/6 cable loss, especially on new install. Check Cat-5 Extender, if
present. If fault present on all EH ports, replace the EH. Otherwise, try another
EH port. If no fault is reported, flag the previous port as unusable and replace
the EH when possible. Otherwise, replace the RAU.
{EF30} Port 6 UL RF path loss is too high
CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check Cat-5E/6 cable loss, especially on new install. Check Cat-5 Extender, if
present. If fault present on all EH ports, replace the EH. Otherwise, try another
EH port. If no fault is reported, flag the previous port as unusable and replace
the EH when possible. Otherwise, replace the RAU.
{EF31} Port 7 UL RF path loss is too high
CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check Cat-5E/6 cable loss, especially on new install. Check Cat-5 Extender, if
present. If fault present on all EH ports, replace the EH. Otherwise, try another
EH port. If no fault is reported, flag the previous port as unusable and replace
the EH when possible. Otherwise, replace the RAU.
{EF32} Port 8 UL RF path loss is too high
CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check Cat-5E/6 cable loss, especially on new install. Check Cat-5 Extender, if
present. If fault present on all EH ports, replace the EH. Otherwise, try another
EH port. If no fault is reported, flag the previous port as unusable and replace
the EH when possible. Otherwise, replace the RAU.
{EF33}Port 1 DL RF path too low
Try another port, if fault persists replace the EH. Otherwise, flag previous port
as unusable and replace the EH when possible
{EF34}Port 2 DL RF path too low
Try another port, if fault persists replace the EH. Otherwise, flag previous port
as unusable and replace the EH when possible
{EF35}Port 3 DL RF path too low
Try another port, if fault persists replace the EH. Otherwise, flag previous port
as unusable and replace the EH when possible
{EF36}Port 4 DL RF path too low
Try another port, if fault persists replace the EH. Otherwise, flag previous port
as unusable and replace the EH when possible
