DIAGNOSTIC LED(S)
LED	Color	Status	Condition
PWR	Green	On	Power is on
PWR	Red	On	Equipment failure occurred during self test
PWR	Green	Blinking	User is logged in
PWR	Red/Green	Blinking	Software is being loaded
PWR	Red	Blinking	Unit is conducting a test
PWR	N/A	Off	Power is off
E1	Red	On	LOS, OOF, AIS or yellow alarm condition detected
E1	Red	Off	LOS, OOF, AIS or yellow alarm condition not detected
TD	Yellow	On	Data is being transmitted from the data port (CN5)
TD	Yellow	Off	Data is not being transmitted from the data port (CN5). Indicative of all zero condition if RTS and CTS are high.
RD	Yellow	On	Data is being received at the data port (CN5)
RD	Yellow	Off	Data is not being recieved at the data port (CN5). Indicative of all zero condition if RTS and CTS are high.
CTS	Yellow	On	CTS signal is high. Unit ready to send data
CTS	Yellow	Off	CTS signal is low
RTS	Yellow	On	RTS signal is high
RTS	Yellow	Off	RTS signal is low
