I believe if you connect a terminal (or something pretending to be a
terminal) to the serial port on the management module, you will be able
to reset it to factory defaults during the boot process. Start with
9600/8/n/1 and increase speed until the terminal works. Every switch
I've ever seen works this way. That 3COM switch supports multiple
protocols and should work well in a vintage network - at least I hope it
does when I have time to play with mine again.

I reset this unit? Mind you, there is a socketed flash SIMM

kettle of fish.
Is it a CoreBuilder 3500? IIRC, there was a backdoor password that gave you
a level of access above the normal.
I can't remember what it is at the moment, but I will have a dig around and
see if I still have the old email.
