I'm not familiar with the Cabletron switches but Gregg is correct only if you just want more ports available. If you are trying to keep a flat network though, you need to do something like you mention in your last paragraph (not the COM ports; those are for management/configuration): you'll need to have something provided by the manufacturer that joins the backplanes of the switches into one switch fabric. With Gregg's scenario, you'll have all the traffic on the second switch concentrated on that one port you cascaded off the first. Maybe that is fine in your situation but it doesn't make for a balanced network load.

Just connect one port from switch A to one port on switch B using an
ethernet crossover cable and two female <--> female RJ45 couplers.
