IP information to your Switch essential if you wish to manage your Switch across the network Manual IP Configuration You can choose to configure the IP information yourself The Switch remembers the information that you enter until you change it again or set the configuration method to Automatic You should use the Manual IP configuration method if m you do not have a DHCP or BootP server on your network or m you want to remove the risk of the IP address ever changing or m 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 configure the Switch IP information manually This makes management simpler and more reliable as it is not dependent on a DHCP or BootP server and eliminates the risk of the IP address changing If you wish to manually enter IP information for your Switch work through the Manually Configuring IP Information section on page 35 Automatic IP Configuration By default the Switch tries to configure itself with IP information without requesting user intervention It tries to obtain an IP address from a DHCP or BootP server on the network If neither server is found the Switch will configure itself with its default IP address 169 254 100 100 if it is operating in a standalone mode and or no other Switches on the network ha
