Do the ports work when the cables are connect? I did some re-search and this seems to be an ongoing issue with 3com switches. It should not effect the use of the switch

page 22 of the 3com user guide for your switch talks about how to use the console cable and how to connect to your pc, I included the link below for your manual, if you don't have it:

You forget the password for the "admin" user account and can no longer perform important management operations.
Use the password recovery method outlined below to define a new password for the "admin" user account:
You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.
You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.

Your superstack 3 should have a 9 pin male connector at the back labeled "console port" you need to connect this to your serial interface on your pc or laptop. With 3Com you also need to set your baud rate to 19200 as this the default for 3Com.

If it's the Power Plus (3C16475BS) model, there should be a reset button inside a small hole on the back. "10 - Recovery Button" Inserting a paperclip or similar to reset. If it's not the Power Plus model and is in fact (3C16475A), this is an unmanaged switch, with no administrative capabilities. You don't need a password.
