To manage a Switch using the command line interface via the local 
console port connection:

1 Ensure you have connected your workstation to the console port correctly 

as described in “Connecting to the Console Port” on page 33.

2 Your Switch is now ready to continue being managed and/or configured 

through the CLI via its console port.

To manage a Switch using the command line interface over a network 
using Telnet:

1 Ensure you have already set up the Switch with IP information as 

described in “Setting Up Overview” on page 30.

2 Check that you have the IP protocol correctly installed on your 

management workstation. You can check this by trying to browse the 
World Wide Web. If you can browse, the IP protocol is installed.

3 Check you can communicate with the Switch by entering a 

ping 

command at the DOS prompt in the following format: 

ping xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the Switch)

If you get an error message, check that your IP information has been 
entered correctly and the Switch is powered up.

4 To open a Telnet session via the DOS prompt, enter the IP address of the 

Switch that you wish to manage in the following format:

telnet xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the Switch)

5 At the login and password prompts, enter 

admin as your user name and 

press Return at the password prompt (or the password of your choice if 
you have already modified the default passwords).

6 If you have logged on correctly, the top-level menu of the command line 

interface for the Switch you wish to manage is displayed as shown in 
Figure 8 on page 35.
