How to know where Catalyst connected?

Can you log into the switches via telnet or with a console connection? If you can then go into config mode "conf t" and enable Cisco Discovery Protocol (CDP) ... "cdp run" then "ctrl z" to exit config mode and do "show cdp neighbours". The output will identify both ports used for the connection.

Re: my other post .. you need to enable cdp on both switches.

You can track your switch with its MAC address.

I didn't post the exact syntax because I don't remember it and I didn't want to tell you something wrong.

If I remember correctly it's something like "show cam" (on CAT OS)

On IOS it should be "show mac-addr..."

Ok I found it now I'm fighting to match the mac addresses.

the command is "sh mac-address-table" and it shows interface to mac correspondence!

Something like this :

If you go to the other switch and type "show interface " and have a look at the mac address. They will be addressed sequencly, from there. Go to the other switch and use the "include" option to find the port they come in on .... "sh mac-add | inc "
