DC Terminal Block Wiring Instructions
The IE-Giga-MiniMc/LFPT TX/SFP can be powered via the DC terminal block. From a
power source, connect to any one positive and any one negative terminal on IE-Giga-
MiniMc/LFPT TX/SFP.
Link Fault Pass Through (LFPT)
LFPT is a troubleshooting feature that combines TX and FX LinkLoss from both the
local and remote IMC devices. This feature, when enabled, by setting the DSW on
the back to ON, will pass a link fault through the device at each segment. Therefore,
if a link fails on one side of the media converter, the media converter will force the
link down on its link partner.
