PC or terminal attachment
To assign an IP address, you must have access to the Command Line Interface (CLI). The CLI is a text-based interface that can be
accessed through a direct serial connection to the device and through Telnet connections.
You need to assign an IP address using the CLI. You can access the CLI by attaching a serial cable to the Console port. After you assign
an IP address, you can access the system through Telnet or Extreme Network Advisor.
Attaching a PC or terminal
Follow the steps given below to attach a management station using the serial port.
1. Connect a PC or terminal to the serial port of the system using a straight-through cable. The serial port has a male DB-9
connector.
NOTE
You need to run a terminal emulation program on the PC.
