T640 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 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.
