Understanding the CIP
Purpose
Inspect the CIP to ensure connection to the Routing Engines, BITS interfaces for the MCS, and alarm relay contacts.
What Is the CIP
The CIP provides an interface through which you can connect to the M40e and M160 Routing Engines, BITS interfaces for the MCS, and alarm relay contacts (see Figure 157).
The CIP has two sets of ports you use to connect the Routing Engines to external management devices. From these management devices, you can use the JUNOS software command-line interface (CLI) to configure and monitor the router.
The upper set of ports, labeled HOST0, connect to the Routing Engine in slot RE0, and the lower set of ports, labeled HOST1, connect to the Routing Engine in slot RE1.
Each HOST port 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-Mbps and 100-Mbps connections. Two small LEDs on the left edge of the port indicate the connection in use: the amber 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.
At the center of the CIP are two ports labeled BITS A and BITS B. These are the BITS connectors to the MCS. The router does not support BITS input, so these ports currently do not function.
The CIP has two sets of 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 BITS interface ports.
The CIP is located on the left side of the M40e and M160 router Flexible PIC Concentrator (FPC) card cage (see Figure 158).
The CIP is field-replaceable, but is not hot-removable, hot-insertable, or hot-pluggable. You must power down the router before removing or installing it.
