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:
1. Connect the female connector of the RS-232 cable directly to the console port on the Switch, and tighten the
captive retaining screws.
2. 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:
a. Select the appropriate serial port (COM port 1 or COM port 2).
b. Set the data rate to 9600 baud.
c. Set the data format to 8 data bits, 1 stop bit, and no parity.
d. Set flow control to
none
.
e. Under

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.
g. 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.
h. After the boot sequence completes, the console login screen displays.
i. 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.
j. 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 Manual
on the documentation CD for a list of all commands and additional information on using the
CLI.
k. When you have completed your tasks, exit the session with the
logout
command or close the emulator program.
Password Protection
The DGS-3312SR 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.
To create an administrator-level account for the Switch, do the following:
