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

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.

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
