the following ports:
—Connects the Routing Engine through an Ethernet connection to a
ETHERNET
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. Two small LEDs on the right edge of the port
indicate the connection in use: the LED labeled
10-Mbps or 100-Mbps connection, and the LED labeled
is passing through the port.
—Connects the Routing Engine to a system console through an RS-232
CONSOLE
(EIA-232) serial cable.
— Connects the Routing Engine to a laptop, modem, or other auxiliary device
AUX
through an RS-232 (EIA-232) serial cable.

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.
