I haven't worked with these switches but generally settings such as ip address and factory defaults can be set through the Console Interface (CLI). You will need a null-modem cable to access this and a terminal client (Windows Hyperterminal works).

Hope that helps

You might consider trying to upgrade the BIOS's on the affected switches

Managed switches you can enter the default ip into a web browser, login and "manage" settings" this default IP will be vendor specific. Unmanaged you just plug in devices and that's about it. Managed switches you will pay a lot more for. Some lower end ones maybe several hundred dollars and up. If you are buying switches at Best Buy they are almost all unmanaged.

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.
My next and only other suggestion is to invest in a "LAN cable tester". In my area, you can find cheap ones for U$20.
The tester will allow you to check connectivity between any two ports, and allows you to test both patch links and individual CAT5/6 cables.
Good luck!
