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

The CIP is located at the left side of the FPC card cage, above the front electrostatic discharge point. The CIP is hot-pluggable.
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:
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.
![]() | Note: The LEDs for an RE-C1800 are always yellow for both a 10-Mbps connection and 100-Mbps connection. |
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.
