D-Link DES-3552 [28/260] Connecting the console port rs 232 dce

DES-3550 Fast Ethernet Layer 2 Switch

Connecting the Console Port (RS-232 DCE)

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 female 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:

3. Select the appropriate serial port (COM port 1 or COM port 2).

4. Set the data rate to 9600 baud.

5. Set the data format to 8 data bits, 1 stop bit, and no parity.

6. Set flow control to none.

7. Under Properties, select VT100 for Emulation mode.

8. Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that you select Terminal keys (not Windows

keys).

NOTE: When you use HyperTerminal with the Microsoft® Windows® 2000 operating sys-

tem, 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.

9. 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.

10. After the boot sequence completes, the console login screen displays.

11. 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.

12. 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 DES-3550 Command

Line Interface Reference Manual on the documentation CD for a list of all commands and additional

information on using the CLI.

13. When you have completed your tasks, exit the session with the logout command or close the emulator program.
