LevelOne GSW-1290 Gigabit Layer2 SNMP Switch
Connecting the Console Port
The Switch provides an RS-232 serial port that enables a connection to a computer or terminal for
monitoring and configuring the Switch. This port is a male DB-9 connector, implemented as a data terminal
equipment (DTE) connection.
To use the console port, you need the following equipment:
•
A terminal or a computer with both a serial port and the ability to emulate a terminal
•
A null modem or crossover RS-232 cable with a female DB-9 connector for the console port on
the Switch
•
To connect a terminal to the console port:
•
Connect the female connector of the RS-232 cable directly to the console port on the Switch, and
tighten the captive retaining screws.
•
Connect the other end of the cable to a terminal or to the serial connector of a computer running
terminal emulation software. Set the terminal emulation software as follows:
•
Select the appropriate serial port (COM port 1 or COM port 2).
•
Set the data rate to 9600 baud.
•
Set the data format to 8 data bits, 1 stop bit, and no parity.
•
Set flow control to
none
.
•
Under Properties, select VT100 for Emulation mode.
•
Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that you select Terminal keys
(
not Windows keys).
NOTICE:
When you use HyperTerminal with the Microsoft
®
Windows
®
2000 operating
system, ensure that you have Windows 2000 Service Pack 2 or later installed.
Windows 2000 Service Pack 2 allows you to use arrow keys in HyperTerminal’s VT100
emulation. See
www.microsoft.com for information on Windows 2000 service packs.
After you have correctly set up the terminal, plug the power cable into the power receptacle on the back of
the Switch. The boot sequence appears in the terminal.
After the boot sequence completes, the console login screen displays.
If you have not logged into the command line interface (CLI) program, press the Enter key at the User
name and password prompts. There is no default user name and password for the Switch, user names and
passwords must first be created by the administrator. If you have previously set up user accounts, log in and
continue to configure the Switch.
Enter the commands to complete your desired tasks. Many commands require administrator-level access
privileges. Read the next section for more information on setting up user accounts. See the
Command Line
Reference on the documentation CD for a list of all commands and additional information on using the CLI.
When you have completed your tasks, exit the session with the
logout
command or close the emulator
program.
Password Protection
The GSW-1290 does not have a default user name and password. One of the first tasks when settings up the
Switch is to create user accounts. If you log in using a predefined administrator-level user name you have
privileged access to the Switch’s management software.
After your initial login, define new passwords for both default user names to prevent unauthorized access to
the Switch, and record the passwords for future reference.
