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.
