Exclamation No access to 4550T via GUI/Console

I have a problem which has been going on for over a month now and is really starting to become a serious issue for me. it is about 4550T-PWR switch.i have no information about IP and password .in other hands I am unable to access the switch via the web interface. I connected to it with a cat5 cable and set my NIC to be on the same IP subnet as the documented switch IP address then I used Wireshark and found MAC address but switch say hello as 0.0.0.0 in result I could not connect via IP address.
next, I tried the console port. This is where it gets really frustrating. I have attached to the console port using every combination of cable I could find a suggestion for on the internet. I first used a straight through female to female serial cable on a USB/Serial adapter without luck. In PuTTy and Hyper Terminal it seems to make a connection and does not time out, yet there is no text displayed on the screen. I have tried control+Y and various other key combinations to elicit some type of response but have come up empty-handed.

If anyone could please let me know of any other way either to access or to set this switch back to defaults.



Thanks in advanced
