• If the second power supply module is not needed, you can mask this alarm.
Example 3:
Switch Alarm: RM Problem
RM I/O Timeout
There is a fault. Communication has been lost to the Redundant Modem. The front panel LED
“Unit Status” will be red.
Suggestions:
• Check Cable Connections – refer to Chapter 4. CABLES AND
CONNECTIONS.
• Check Modem Configurations – refer to Chapter 6. CONFIGURING MODEMS FOR
1:N REDUNDANCY.
Example 4:
Switch Alarm: RM Problem
MGC refused, code:12 TFT
There is a fault. COMMs are good to the Redundant Modem, but the configuration of the
bridged Traffic Modem cannot be configured into the Redundant Modem. The front panel LED
“Unit Status” will be red.
Suggestion: Ensure that the most capable modem – with regard to FAST options, installed
options, etc. (e.g. Turbo card, firmware version, and hardware revision) – is used as the
Redundant Modem. The code indicates the parameter within the MGC configuration string that
is causing rejection by the Redundant Modem. The three-letter instruction code is indicated also
to assist you in decoding the problem parameters.\
