6.1.1 Front Panel LED Indicators
The behavior of the eight front panel LEDs adjacent to the keypad indicate the operation status of
the CDM-710G, and are described as follows:
LED COLOR CONDITION/STATE
UNIT STATUS
Green No Unit Faults or Alarms exists.
Orange A Unit Alarm exists.
Red A Unit Fault exists.
Tx STATUS
Green No Tx Traffic Faults or Alarms exists.
Orange A Tx Traffic Alarm exists.
Red A Traffic Fault exists.
Off Unit not configured for Modulator.
Rx STATUS
Green No Rx Traffic Faults or Alarms exists.
Orange An Rx Traffic Alarm exists.
Red An Rx Fault exists.
Off Unit not configured for Demodulator.
ONLINE
Green The Unit is On Line, and carrying traffic
Off
The Unit is Off Line (standby) – forced by externally connected 1:1 or
1:N redundancy system
STORED
EVENT
Orange
There is a Stored Event in the log that may either be viewed from the
front panel or retrieved via the remote control interface.
Off There are no Stored Events.
TRANSMITTER
ON
Green
Transmitter is currently on. This indicator reflects the actual condition
of the transmitter, as opposed to the programmed condition.
Off Transmitter is currently OFF.
REMOTE
Green
The Unit is in Remote Communication Mode.
Local monitoring is possible, but no local control.
Off
The Unit is in Local Mode – remote monitoring is possible, but no
remote control.
TEST MODE
Green A Test Mode is selected; e.g., IF Loopback.
Off There is no Test Mode currently selected.
IMPORTANT
In general, the Alarm relay state will reflect the
state of the Front Panel LEDs. For instance, if the
Unit Status LED is red, the Unit Alarm relay will
be active, etc. The one exception is the Transmit
Traffic relay; this will only be activated if a
Transmit Traffic Fault exists – it does not reflect
the state of the Tx carrier.
