Cascading DC Power
If installing multiple IE-ModeConverters on a DIN rail,
you can use one DC input source and then cascade from
one DC terminal block to the next, until reaching the
maximum electrical current available.
LED Operation
The IE-ModeConverter contains four status LED
indicators. Each LED is dual color and has three
states: off, red, or green. A loss of signal on one
SFP causes the TX of the other SFP to turn off.
This action does not activate the red TX Fault
LED.
LED Color or State
Red OFF Green
PWR
Card does not pass the
self-test. Unit does not have
power. Power is applied to the card.
All internal self-test functions
must pass before the PWR
LED is green.

LED transmitter has an
active fault. No active fault on
transmitter.
LOS indication on
receiver. Valid signal is detected by
the SFP and LED transmitter
is not in fault.
MSA LEDs One or both SFPs are
not installed or not
detected. The TX
inhibit must not be
active if a SFP is
missing. Or, both SFPs
are installed, but their
speed settings are
different. This
condition disables both
SFPs. One or both SFPs
are not an IMC
Networks’ device.
The may still
function but IMC
cannot warrant
functionality or
performance using
non IMC SFPs.
Both SFPs are installed with
IMC Networks’ devices at
the same speed setting.
