Diagnostic Procedures
Use the following table when diagnosing system problems. While troubleshooting,
you can copy the blank table on page 12 and use it to record the LED colors on the
Main Hub, the particular Expansion Hub indicating a fault, and the RAUs
connected to it. This is necessary because the Main Hub, Expansion Hubs and
RAUs might be geographically distributed.
To determine where the fault might be
1
Go to the Main Hub and record the LEDs. The Main Hub indicates which
Expansion Hub may be faulty by lighting one of its port LEDs red.
2
Go to the Expansion Hub attached to the port that has a red LED.
3
Record that Expansion Hub’s LEDs. The Expansion Hub indicates which
RAU(s) may be faulty by lighting its antenna LED red.
4
Go to the RAU(s) connected to the Expansion Hub port indicating a fault.
Record the error.
5
Compare your filled in table to the Diagnostic Table below and begin
troubleshooting according to the notes indicated for your situation.
