RFC Link Up Status
The RF Link Up Status will indicate NO on the TRACER System Status page when communication
between the BBP and RFC has failed.
Possible Cause
•
Failure of the IF cable. .................................................................................... 1
•
Fuse blown in BBP. ........................................................................................ 2
•
Loose cable connections in the RFC. ............................................................. 3
•
Failure of the BBP. ......................................................................................... 4
•
Failure of the RFC. ......................................................................................... 5
Recommended Actions:
1.
Check the IF cable for shorts or loose connections.
2.
Check for blown fuse in the BBP. This fuse is accessed by removing the top of the
Baseband Processor, and is located on the left side of the chassis when facing the front
panel. If this fuse is open, verify that the coax connections are correctly installed and check
the BBP to RFC coaxial cable for a short.
3.
Check all connections in the RFC.
4.
Replace the BBP.
5.
Replace the RFC.
