We're using 3COM Linkbuilder FMS II (10baseT) hubs, with a single management module, in the first hub, of a cascading array of hubs. The setup is done from within the hub's management software, (via telnet to an IP address, or a serial link - kinda like a router), there are quite a few options you can use, visit 3Com's site and read the help pages on the hub's management. (note, if the hub with the management module dies...you're gonna be screwed unless you've got another on hand).
