4.1 CLI
Management
The command-line interface (CLI) is a text-based interface into the switch. To use the CLI, you can Telnet
into the switch, or you can connect to the switch’s RS-232 port. The following are detailed instructions to
set up an RS-232 connection:
1. Take the null modem cable that comes with the switch out of the box.
2. Connect one end of the cable into the RS-232 serial port on the switch, and the other end into an RS-
232 serial port on your computer.
3. Start a terminal program on your computer (by default Windows uses HyperTerminal)
4. Configure the connection as shown below.

To Telnet into the switch, connect to the Ethernet port of the switch, and then open a command prompt in
Windows. In the command prompt, type “telnet <ip address>” where <ip address> is the IP address of
the switch. The same rules apply to connecting to the switch via Telnet as via the web interface in terms
of being on the same subnet as the switch.
4.1.1 Login
The default username and password are shown below. Be sure to change the password as soon as
possible for security purposes.
Username: admin
Password: admin
After you login successfully, you will see a prompt “SS2GD8I#” if you are the first person to login and you
have administrator rights, otherwise the prompt may appear as “SS2GD8I$“. The former means you have
administrator rights and have full access to the switch. The latter means you only have guest rights and
are only allowed to view the system without changing any settings.
4.2 CLI
Commands
To see the commands available, use the “?” command at the prompt. Commands fall into two categories,
global commands and local commands. Global commands can be used at any time and are listed in
section 4.2.1, whereas local commands only work in a specific submenu and are listed in section 4.2.2.
The same local command will perform different functions depending on which submenu the user is
currently in.
