The resetting of the password requires the installation of a console cable to the console port.

Be sure the terminal emulator program is set to VT-100 management using compatible, 38400 baud rate, no parity, 8 data bits and Console connection one stop bit.

Use the included cable, or be sure that the pin-out complies with a standard null-modem cable

Once the cable is connected, reboot the switch. Type a Ctrl/C until you enter the failsafe mode. This will be denoted with the prompt: “CFE>”
At the prompt execute the following commands:

CFE> passwrd
CFE> reset -sysreset

At this point the password has been reset.

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!
