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 47

IP Configuration
You can use one of the following methods to allocate IP information to your 
switch (essential if you wish to manage your Switch across the network).
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, or
you want to remove the risk of the IP address ever changing, or
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 assign a known IP address to 
your switch. This makes management simpler and more reliable as it is not
