CAUTION: To protect your switch from unauthorized access, you must change all three default passwords 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 50.

IP Configuration In order for the device to be remotely managed, it requires an IP address. You can use one of the following methods to allocate IP information to your switch.

Configuring IP Manually

When you configure the IP information, 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 or BootP server on your network

■you want to remove the risk of the IP address ever changing

■your DHCP or BootP 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 assign a known IP address to your switch. This makes management simpler and more reliable as it is not
