LED	Description
Power	Solid GREEN to indicate the unit is powered on.
CopperLink	(Active Green) Solid green (ON) to indicate that the
Ethernet	end-to-end CopperLink link between the CopperLink
Extender Link	Ethernet Extenders is established. The CopperLink
	Ethernet Extender LED is OFF when the link is down.
CopperLink	(Active Yellow) Flashes YELLOW to indicate the pro-
Ethernet	cessor is correcting an error in the data thus prevent-
Extender QOL	ing the transmission of corrupted data to the Ethernet
	port. The more error corrections, the more often the
	LED blinks. If the light remains lit continuously, it
	means that the CopperLink line is noisy—although
	the data at the Ethernet port remains uncorrupted.
	Further impairment of the line however, risks having
	the line fail, as indicated by the green CopperLink
	Ethernet Extender Link LED extinguishing.
Ethernet Link	(Active Green) Solid Green indicates that
	10/100Base-T Ethernet link has been established.
Ethernet Activity	(Active Yellow) Flashes yellow to indicate Ethernet
	activity on the CopperLink Ethernet Extender’s
	10/100Base-T Ethernet port.
