Unless you have to have a fiber connection with a transceiver.  There is no physical reason why a cable should connect to a certain port.  You would designate the switchport mode in the configuration in order to make the connection functional. Can you respond back with your show run output and a description of your physical environment so we can get a better understanding or what is going on.
I have a 6224 switch that is not setup with any special VLANs or routing. It's basically serving as a layer 2 switch.  I have a Sonicwall TZ210 as my firewall router connected to my ISP.  I'm running into some issues related to too many switches connected to each other.  I wanted to make sure that my sonicwall is conected to the correct port on my switch.  The guys who setup it connected the LAN port of the sonicwall to port 15 on the switch.  It's not setup as any special port.  Shouldn't it be plugged into one of the ports 21 -24.  I have a GBIC plugged into 24 that connects to another powerconnect 2427.  Thanks
