M320 Connector Interface Panel (CIP) Description

 

The CIP is located at the left side of the FPC card cage. The front electrostatic discharge point is located near the bottom of the CIP.

CIP Components

The Connector Interface Panel (CIP) consists of Ethernet, console, and auxiliary connectors for the Routing Engines and alarm relay contacts (see Figure 1).

Routing Engine Ports

The CIP has two sets of ports that you use to connect the Routing Engines to external management devices. From these management devices, you can use the CLI to configure the router.

The upper set of ports, labeled HOST 0, connects to the Routing Engine in slot RE0; and the lower set, labeled HOST 1, connects to the Routing Engine in slot RE1. Each set includes the following ports:

  • ETHERNET—Connects the Routing Engine through an Ethernet connection to a 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 ETHERNET lights yellow or green for a 10-Mbps or 100-Mbps connection, and the LED labeled ACT lights green when traffic is passing through the port.

  • CONSOLE—Connects the Routing Engine to a system console through an RS-232 (EIA-232) serial cable.

  • AUX— Connects the Routing Engine to a laptop, modem, or other auxiliary device 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 (0.08 and 2.08 mm2), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.
