Remote Access Unit Warnings
Table 9-6 Warnings Reported by the RAU
Warning Message Action
{RW17}The DL RF path loss is too high CAT-5 cable is poorly terminated, re-crimp the connector; no RF uplink is
detected at all.
Check the CAT-5E/6 cable for shorts/opens, especially on new installations.
Check the CAT-5 Extender, if present. If the warning is common to more than
one RAU, replace the EH/Accel Hub. Try another port. If no warning is
reported, flag the previous port as unusable and replace the Hub when possible.
Otherwise, replace the RAU when possible.
{RW18}DL RF path operating at minimum
gain
Check CAT-5E/6 cable loss, especially on new installations. Check the CAT-5
Extender, if present, and validate that minimum cable length requirements are
met. If the warning is common to more than one RAU, replace the EH/Accel
Hub when possible. Try another port. If no warning is reported, flag the previ-
ous port as unusable and replace the Hub when possible. Otherwise, replace the
RAU when possible.
{RW19}Antenna Disconnected Check the antenna connection and rerun the system test. (You can select the
antenna disconnect reporting for status or warning.)
