Problem with connecting two 24 port 3 com switches
If the whole network looses connections when you connect the two switches together, there may be a loop in the network...that is, there could be another path for data to pass between the switches.

I don't know anything about these units, nor do I have time to source any docs for you, but maybe you can try connecting a PC directly to the port your patch panel is connecting the the switch from, you can at least see if that port is working.
