Page 37: Ip Configuration
(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. -
