Premier Mounts CDM-600 specifications Front Panel LED Indicators, Led, Color Condition

CDM-600 Satellite Modem	Revision 7
Front Panel Operation	MN/CDM600.IOM

The behavior of the front panel LEDs is described below in Table 6-1.

			Table 6-1. Front Panel LED Indicators
LED	Color		Condition
Unit	Red		A Unit Fault exists (Example: PSU fault)
	Orange		No Unit Faults, but a Traffic Fault exists
Status
	Green		No Unit Faults, or Traffic Faults
Transmit	Green		No Tx Traffic Faults
Traffic	Off	A Tx Traffic fault exists OR the Tx Carrier is in OFF state
Receive	Green		No Rx Traffic Faults (demod and Viterbi decoder are locked, everything is OK)
Traffic	Off	An Rx Traffic fault exists (the demod may still be OK)
On line	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
	Orange		There is a Stored Event in the log, which can be viewed from the front panel, or
Stored Event			retrieved via the remote control interface
	Off	There are no Stored Events
	Orange		The Unit is in Remote Mode - local monitoring is possible, but no local control
Remote	Off	The Unit is in Local Mode - remote monitoring is possible, but no remote control
	Flashing		ODU control has been enabled, and there is a communications fault, or there is a
			ODU status fault
	Orange		Framing on, EDMAC on, and unit defined as Slave - local monitoring is possible,
EDMAC Mode			but no local control
	Off	Either no EDMAC, EDMAC Master, or Transparent mode is selected
Test Mode	Orange		A Test Mode is selected (Example: IF Loopback)
	Off	There is no Test Mode currently selected

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

IMPORTANT Traffic Fault exists – it does not reflect the state of the TX carrier.
