Setting Up Management Access

Before you power up the system, you must set up a management console. (See “Connecting to a Console Terminal” on page 60.) You use the console to communicate with the system during the power-up process, set an IP address, and manage the system using the command-line interface (CLI).

You can manage and monitor the router through either of these methods:

Console terminal—Connect a console (PC, Macintosh, or UNIX workstation) directly to the system’s RS-232 serial port.

Remote console—Connect the 10/100Base-T port on the SRP I/O module to an

Ethernet network, and run Telnet from a remote console.

For initial access to the system, you need to physically connect your console directly to the system’s RS-232 port. Through this connection you can use the CLI to set an IP address on the system. After you configure the IP address, you can access the system remotely (for example, via Telnet).
