Link Fault Detection LED Activity (PCI Version)
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
McPC 10/100 is in
Force 10
or
Force 100
mode, where the fault occurs, etc. For
questions, please contact Technical Support.
NOTE
Twisted pair AND fiber optic cables must be connected, and the twisted pair
crossover/pass-through switch set correctly, before either LNK LED will glow solid.
