Exception and Alarm States
The first indication of a problem is usually an illuminated ALARM LED on one or more of the
modules. The first place to look is the Alarm or Alarm/Relay module and see if the PWR/Alarm
LED is RED.

8.2 Redundant Units
The active radio can be identified by the corresponding LED on the alarm/relay module as well
as the active LED on the radio module. The active unit is normally selected automatically. For
troubleshooting, the toggle switch can be used to manually set the active radio. Alternatively, the
switch can remain in the automatic position, and the active radio can be selected via the web UI,
or CLI.
8.3 Technical Assistance
Factory technical assistance is available by contacting GE MDS during business hours (8:30 AM
to 6:00 PM Eastern Time). For telephone assistance, call (585) 241-5510, or visit our website at
www.gemds.com for additional contact options.
8.4 Replacing Modules
Component-level repair of a transceiver board in the field is not recommended due to the
complex nature of the circuitry and the use of surface-mount technology throughout the radio.
You should return malfunctioning assemblies to the factory (or authorized service center) for
repair or replacement.
