36CHAPTER 3: SETTING UP FOR MANAGEMENT

Viewing	If you allow the Switch to automatically configure its own IP information
Automatically	you need to discover and view the IP information before you can begin to
Configured IP	manage the Switch. You can discover the IP information in two ways:
Information	■ Using 3Com Network Supervisor — this application will auto-discover

	the Switch and display the automatically allocated IP information
	assigned to the Switch.
	■ Connecting to the Console Port — connect a workstation using a
	console cable to the console port of the Switch. You can then view the
	IP information automatically assigned to the Switch using the
	command line interface (CLI).

Using 3Com Network You can use the 3Com Network Supervisor application provided on the Supervisor CD-ROM that accompanies your Switch to discover the automatically

allocated IP information.

1Connect your Switch to the network.

2Power-up the Switch and wait for two minutes.

3Launch 3Com Network Supervisor and run the Auto-discovery wizard.

3Com Network Supervisor will auto-discover the new Switch and display the IP information that has been automatically allocated to the Switch.

Most DHCP servers allow static IP addresses to be configured so that you know what IP address the Switch will be given. Refer to the documentation that accompanies your DHCP server.

If your network does not have a DHCP server, the workstation running 3Com Network Supervisor must be on the same subnet as the Switch, because Auto-IP addresses are non-routable.

Connecting to the Alternatively, you can view the automatically configured IP information Console Port via the command line interface (CLI) through a connection to the console

port. (This example describes a local connection to the console port, rather than a remote one via a modem.)

Pre-requisites

■A workstation with terminal emulation software installed, such as Microsoft Hyperterminal. This software allows you to communicate with the Switch via the console port directly, or through a modem.

■Documentation supplied with the terminal emulation software.
