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

A network hub allows computers to be connected together...up to 12 of
them in this case...but it doesn't provided any other network services
such as DHCP (automatic address assignment). I may be able to provide
better information if you can tell me what operating system you're
using.
Here's one way to set up a network for file sharing...if you're using Microsoft Windows XP:
Connect
the computers to the hub and turn them all on. You may need to manually
assign addresses to the computers, (ask if you need a detailed
procedure) but Windows XP will usually assign itself a default address.
On each computer, click on Start -- Control Panel -- System --
Computer Name -- Network ID -- Now give the computer a name and
Workgroup name. In order for the computers to share files, the workgroup names must be identical on every computer.
Next, click on My Computer and Right-Click on Shared Documents -- Sharing & Security -- Share this folder on the network
Now if you click on My Network Places, it should be possible to see the shared folders on the other computers.
Good luck with this....and I hope this is helpful!!

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.
