Port LEDs

The ports on the PD-Switch include diagnostic LEDs that indicate unique information about the port functionality and status.

PD-Switch-TX/5

For all units with 5 copper ports, the two LEDs associated with each twisted pair port are defined as follows:

Port	LED Name	Color	Function
		OFF	No link signal detected on copper port
	LNK/ACT	GREEN	Glows green when a twisted pair link is
			established
TX
		Flash GREEN	Activity is detected on the port
	FDX	OFF	Port is operating in Half Duplex
		AMBER	Port is operating in Full Duplex

PD-Switch-TX/3+FX

On units with a 1x9 fiber port, the FDX LED of port 3 has been re-defined as the “FX- LNK/ACT” LED for the fiber port. Note that the “LNK” LED requires a valid Link signal and no Far-End-Fault (FEF) from the fiber line.

Port	LED Name	Color	Function
		OFF	FEF or no link signal detected on FX port
1X9	LNK/ACT	AMBER	Glows amber when the fiber link is
			established
		Flash AMBER	Activity is detected on the port
