C.6 Warning /Status Messages for RAUs

In Table C-6, the message number is in the following form:

[Rnn]/X where nn equals the message number, and X equals the default of either Sta-

tus (S) or Warning (W).

Table C-6 Warning/Status Messages for RAUs

Message

Number

Default Description Reason/Action

[R01]/W Temperature High. Check RAU location for excessive temperature; check for

air flow blockage and/or incorrect installation. Move the

RAU to a cooler environment.

[R02]/W No communications from Hub. Check the cable for high RF loss. Switch the cable connec-

tion to a different hub port. If the problem persists, replace

the RAU.

[R03]/W DL RF path loss is too high. Check the cable for high RF loss. Switch the cable connec-

tion to a different hub port. If the problem persists, replace

the RAU.

[R04]/W DL RF path exceeds maximum

gain.

Check the Hub for proper operation; switch the cable con-

nection to a different hub port. If the problem persists,

replace the RAU.

[R05]/W DL RF path problem (Band 1). Unable to complete the DL system end-to-end test, replace

the RAU when possible.

[R06]/S DL RF path problem (Band 2). Unable to complete the DL system end-to-end test, replace

the RAU when possible.

[R07]/S DL RF path problem (Band 3). Unable to complete the DL system end-to-end test, replace

the RAU when possible.

[R08]/S System test required. Run system test.

[R09]/S Antenna Disconnected. Check RAU antenna connection; re-run system test.

[R10]/S UL RF path problem (Band 1). Unable to complete the UL system end-to-end test, replace

the RAU when possible.

[R11]/S UL RF path problem (Band 2). Unable to complete the UL system end-to-end test, replace

the RAU when possible.

[R12]/S UL RF path problem (Band 3). Unable to complete the UL system end-to-end test, replace

the RAU when possible.

[R13]/S Problem detected in the RAU. Contact LGC Wireless Support for more information.

[R14]/S Problem detected in the RAU. Contact LGC Wireless Support for more information.

[R15]/S Problem detected in the RAU. Contact LGC Wireless Support for more information.

[R16]/S Problem detected in the RAU. Contact LGC Wireless Support for more information.
