7.4 IMUX Card Troubleshooting
On power-up, the IMUX card performs a self-test. This is the only diagnostic available for the
IMUX.
The indications that a IMUX is not on-line are:
• Continuous amber alarm LED on front panel AFTER the system has been registered
during initial installation. (Prior to registration, the amber LED is an indication that
registration needs to occur before the system can be fully operational.
• Inability to communicate with the system by any means (VT-100 Term, Telnet, etc.).
If the IMUX card is determined to be faulty, replace it and return the faulty unit for repair to
the location specified by your distributor.
