T4000 Connector Interface Panel (CIP) Description


T4000 Connector Interface Panel (CIP) Components

The Connector Interface Panel (CIP) consists of Ethernet, console, and auxiliary ports for the Routing Engines and alarm relay contacts (see Figure 1). The CIP is located at the left side of the FPC card cage, above the front electrostatic discharge point.

The CIP is hot-pluggable.

Management Ports

The CIP has two sets of management ports (see Figure 1) that you use to connect the Routing Engines to external management devices. 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. From these management devices, you can use the CLI to configure the router.

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 left edge of the port indicate the connection in use: the yellow LED lights for a 10-Mbps connection, and the green LED lights for a 100-Mbps connection.

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

  • AUXILIARY— Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.

T4000 Alarm Relay Contacts

The CIP has two alarm relay contacts for connecting the router to external alarm devices (see Figure 1). 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.
