LED Description
Power Solid GREEN to indicate the unit is powered on.
CopperLink
Ethernet
Extender Link (Active Green) Solid green (ON) to indicate that the
end-to-end CopperLink link between the CopperLink
Ethernet Extenders is established. The CopperLink
Ethernet Extender LED is OFF when the link is down.
CopperLink
Ethernet
Extender QOL (Active Yellow) Flashes YELLOW to indicate the pro-
cessor is correcting an error in the data thus prevent-
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.
