management LAN (or any other device that plugs into an Ethernet connection) for
out-of-band management. The port uses an autosensing RJ-45 connector to support
both 10- and 100-Mbps connections.

in use: the yellow LED lights for a 10-Mbps connection, and the green LED lights for
a 100-Mbps connection.
NOTE: When an RE-C1800 is installed, the connection LED is always
yellow for both a 10-Mbps connection and 100-Mbps connection.
CONSOLE —Connects the Routing Engine to a system console through an RS-232
(EIA-232) serial cable.
— Connects the Routing Engine to a laptop, modem, or other auxiliary device
AUXILIARY
through an RS-232 (EIA-232) serial cable.

Alarm Relay Contacts

The CIP has two alarm relay contacts for connecting the router to external alarm devices.
Whenever a system condition triggers either the red or yellow alarm on the craft interface,
the alarm relay contacts are also activated. The alarm relay contacts are located below
the Routing Engine ports. The terminal blocks that plug into the alarm relay contacts are
supplied with the router. They accept wire of any gauge between 28-AWG and 14-AWG
2
(0.08 and 2.08 mm ), which is not provided. Use the gauge of wire appropriate for the
external device you are connecting.
