LED Operation
The IE-iMcV-T1/E1/J1-LineTerm, TP/SFP module features several diagnostic LEDs per
port. The following LED display functions are provided:
Copper Port LEDs
ER
Flashes yellow whenever a line code violation is
received.
LOS Glows red when the RJ-48 is receiving no signal and is
in an LOS ALARM state. This condition will also send
an RAI signal to the fiber port. If the Fault Loopback is
set to ON, an AIS will also be sent to the local copper
port.
PRBS Glows green when the copper port receives a valid
Pseudorandom Bit Sequence (PRBS). It is OFF when
the port is not receiving a PRBS.
TEST Glows yellow when any Loopback mode is active.
Fiber Port LEDs
ER Glows yellow when a fiber symbol error has been
received.
LOS Glows red when a fiber link is not established and is in
a LOS ALARM state.
RM Glows green on the REMOTE unit when Remote
Management is enabled. Glows green on the HOST
unit when it has discovered a manageable REMOTE
unit. Under normal operation this LED is the only LED
that is ON at the unit.
RAI Glows yellow when a Remote Alarm Indication (RAI) is
received on the fiber port. This indicates a fault exists
at the far end unit.
NOTE
Unless noted otherwise, any reference is applicable for both the 1x9 and SFP version of
the IE-iMcV-T1/E1/J1-LineTerm in this manual.
