Over the Network

1Check 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.

2Check 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.

3Open your web browser and enter the IP address of the Switch that you wish to manage in the URL locator, for example, in the following format:

http://xxx.xxx.xxx.xxx

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

4At the login and password prompts, enter admin as your user name and enter your password at the password prompt (or just press Return if you have not yet set a password).
