Management
Pre-requisites	■ Ensure you have already set up the Switch with IP information as
	described in “Setting Up Overview” on page 30.
	■ Ensure that the Switch is connected to the network using a
	Category 5 twisted pair Ethernet cable with RJ-45 connectors.
	■ A suitable Web browser.
	Choosing a Browser
	To display the web interface correctly, JavaScript and Cascading Style
	Sheets must be enabled on your browser. These features are enabled on a
	browser by default. You will only need to enable them if you have
	changed your browser settings.
	To enable style sheets in Netscape Navigator 4.76 on Solaris 2.6, open
	Netscape Navigator and select Edit > Preferences > Fonts. Select the Use
	document-specified fonts, including Dynamic Fonts radio button. You
	should also set the font sizes as follows:
	■ Variable Width Font - Size 10.0
	■ Fixed Width Font - Size 12.0
	This ensures that the text spacing is correct. Finally in the Advanced
	category ensure that Enable JavaScript and Enable style sheets are
	checked.

Web Management To manage a Switch using the web interface over an IP network:

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)
