LNK
Twisted Pair Port
Glows green when a twisted pair link is established.

port.
Glows green when Link Fault Detection is enabled.

NOTE
Before either LNK LED will glow solid, the twisted pair and fiber optic cables must be
connected and the twisted pair crossover/ pass-through switch set correctly.
Link Fault Detection LED Activity
When LFD is enabled and a fault occurs on a segment of the media conversion, the
various Link LEDs in that conversion will either blink or extinguish. LEDs may react
differently depending on the type of end devices in the conversion, whether the
iMcV-LIM is in Force 10 or Force 100 mode, where the fault occurs, etc.
