Number Name Description
3 Management FE
interface
Reserved hardware interfaces.
4 AC input power
socket
Connects the power module to an external
power supply system using a power cable with
a 3-pin plug.
5 Equipotential
ground terminal
Uses a 6.8 Ground Cable to reliably ground a
router to protect the router from lightning and
interference.
6 LAN interfaces:
eight input GE
interfaces
Uses an 6.6 Ethernet Cable to connect to the
Ethernet interface of the router.
7 LAN interfaces:
eight output GE
interfaces (PoE
capable)
Connect to other devices for PoE.
NOTE
An Ethernet interface that does not support PoE can
be converted into a PoE-enabled GE interface
through a 180 W PoE midspan. To implement PoE,
connect the output and input GE interfaces to the
corresponding interfaces, for example, connecting the
input GE interface to the GE0 interface on the left
and the output GE interface to the GE0 interface on
the right.
8 RUN/ALM
l Off: The system software is not running or
is resetting.
l Slow blinking green: The system is running
properly.
l Fast blinking green: The system is powering
on or restarting.
Steady red: A system fault has occurred and
requires manual intervention.
9 PoE
l Steady on: The midspan is providing 48 V
power supply normally.
l Off: The midspan does not provide 48 V
power supply normally or is not connected
to any power source.
10 12 V
l Steady on: The power input socket of the
midspan is receiving power normally from a
power source.
l Off: The midspan cannot be powered by the
power source or is not connected to any
power source.
11 and 12 GE electrical
interface indicators
l Steady green: The power supply level for
PDs is 0 to 3.
l Off: The interface is not supplying power to
PDs.
