and monitor the way it works, you have to access the management

software that resides on the switch. This is known as managing the

switch. Managing the switch can help you to improve the efficiency of

the switch and therefore the overall performance of your network.

This section explains the initial set up of the switch and the different

methods of accessing the management software to manage a switch. It

CAUTION: To protect your switch from unauthorized access, you must change the default password as soon as possible, even if you do not intend to actively manage your switch. For more information on default users and changing default passwords, see “Default Users and Passwords” on page 27.

20 CHAPTER 1: GETTING STARTED

IP Configuration The switch’s IP configuration is determined automatically using DHCP, or manually using values you assign.

Automatic IP Configuration using DHCP

By default the switch tries to configure its IP Information without requesting user intervention. It tries to obtain an IP address from a DHCP server on the network.

Default IP Address If no DHCP server is detected, the switch will use its default IP information. The default IP address is 169.254.x.y, where x and y are the last two bytes of its MAC address.

Note: The switch’s default IP address is listed on a label located on the rear of the switch.

If you use automatic IP configuration it is important that the IP address of the switch is static, otherwise the DHCP server can change the switch’s IP addresses and it will be difficult to manage. Most DHCP servers allow static IP addresses to be configured so that you know what IP address will be allocated to the switch. Refer to the documentation that accompanies your DHCP server.

You should use the automatic IP configuration method if:

your network uses DHCP to allocate IP information, or

flexibility is needed. If the switch is deployed onto a different subnet, it will automatically reconfigure itself with an appropriate IP address, instead of you having to manually reconfigure the switch.

If you use the automatic IP configuration method, you need to discover the automatically allocated IP information before you can begin management. Work through the “Viewing IP Information using the Console Port” on page 23.

Manual IP Configuration

When you configure the IP information manually, the switch remembers the information that you enter until you change it again.

You should use the Manual IP configuration method if:

You do not have a DHCP server on your network, or

You want to remove the risk of the IP address ever changing, or

Using the Command Line Interface (CLI) 21

Your DHCP server does not allow you to allocate static IP addresses. (Static IP addresses are necessary to ensure that the switch is always allocated the same IP information.)

For most installations, 3Com recommends that you configure the switch

IP information manually. This makes management simpler and more

reliable as it is not dependent on a DHCP server, and eliminates the risk of

the IP address changing.

To manually enter IP information for your switch, work through the

“Manually set the IP Address using the Console Port” on page 22.

Using the

You can access the switch through the Console port to manually set the

Command Line

IP address, or to view the IP address that was assigned automatically (for

Interface (CLI)

example, by a DHCP server).

For more information about the CLI, refer to “3Com CLI Reference Guide”

on page 195.

Connecting to the

This section describes how to connect to your switch through the

Console Port

Console port.

Prerequisites

A workstation with terminal emulation software installed, such as Microsoft Hyperterminal. This software allows you to communicate with the switch using the console port directly.

Documentation supplied with the terminal emulation software.

The console cable (RJ-45) supplied with your switch.

You can find pin-out diagrams for the cable in Appendix C on page 189.

Refer to the documentation that accompanies the terminal emulation software for more information.

3 Power up the switch. The Power on Self Test (POST) will be performed. The Switch 2916 and 2924 takes approximately one minute to boot.

You are now ready to manually set up the switch with IP information using the command line interface.

You need to have the following information:

IP address

subnet mask

default gateway

Using the Command Line Interface (CLI) 23

1Connect to the switch Console port as described in “Connecting to the Console Port” page 21.
