Open a web browser an put the IP address of your switch in the addresse bar. Once in the web interface, open the Monitoring folder and then click the Port Utilization link. The switch is actually creating graphics of each port utilization.

Much more details are provided in the user manual:

SOURCE: ''!!! WARNING: The switch is not usable !!!''

Unfortunately the show stack isn't showing any results other than it is either a hardware or software fault. I am guessing it is a fault with the hardware as the show version in your first post states "interface Ethernet-controller 4 failed POST POST error status : general error occured".

Ethernet-controller 4 is one if the gigabit ports (poss fibre port), so if you have anything attached to those, disconnect and reboot the switch and see what happens. If that doesn't work, you could try reinstalling the IOS, but at a guess I would say its a hardware fault.

I cann't connect to my switch

The primary connection method for those switches would be serial connection. In the box there should have been a DB9 serial to RJ45 cable. Hyperterminal default settings would allow you to connect.
