Access to Management Functions

There are three ways to access switch management functions:

1.  RS-232 serial port connection (CLI)
2.  Telnet
3.  Web

Note:

Before accessing management functions through Telnet or the Web, you must modify the

IP address, subnet mask, default gateway and DNS through the RS-232 connection.

4.1

Using the RS-232 Serial Port Connection

To configure the switch via the RS-232 serial port connection, follow these steps:

1.  Connect the serial cable included with your switch to your workstation.
2.  Connect the serial cable to console connector on the back of your switch.
3.  Run the terminal emulator (Example: HyperTerminal) using the following settings.

a. Baud rate (bits per second):

115200

b. Data bits:

8

c. Parity:

N

d. Stop bits:

1

e. Flow control:

None

4. When you complete the connection, press the

Enter

key.

5. Turn on the switch.
6. The default login is:

a. Username =

admin

b. Password =

admin
