Make sure your serial port on your PC is set to: 9600, 8, no parity, 1 stop bit, no flow control.
Make sure you are using a NULL modem serial cable.
If you have these correct, then on power-up, you should be able to see output on the serial port from the boot code. When you do, you will see the output pause with a menu that allows you to choose the "boot menu", choose it. The boot menu will have a choice for resetting the switch to factory defaults.
I had this issue. I used the DB9 LED tester to evaluate the communication. The RXD Led would wink on boot up but did not go red/green. Just could see data flowing. I pulled the board out of the case. No Batt that I could see. On the bottom of the board near where the serial is connected is a small chip. I ordered some of these and changed it out (really I had someone do it for me) and now I have red/green and data on the computer with 9600 & a Null cable. It was about to go to the electronic scrap yard. Mouser Electronics ADM3202ARUZ. Not expensive but real small. I did have two of the 6224's with one dead and one good. Use Putty with serial to communicate with the switch.

I used those settings and the correct cord type, but no dice.
