Since it was running 5.0A, it was an "old" P75.... >According to the FTP site, I thought I had a 'new' P75 (P75-1SBRI-UK, s/n I'll check that out, since the serial number test is NOT absolute. The BEST way to tell if you have new vs old is if there is a switch on the back of the P75: yes, it's the older unit (b.p75); no, it's the new version (b2.p75). Also on the screen/menu you can see what binary it's currently running in the system status windows.

Turn off the P75. Connect a terminal to the serial port at 57600baud, then jumper P1 on the motherboard (yes, you have to open it up). Power up, and you should get a prompt - at the prompt type DF - it will download the image (b.p75) now via the serial port XMODEM procedure as documented on the FTP site. When it's completed, remove the jumper any re-cycle. You should now have access to the menus via the serial port at 9600baud (or 57600 if not).
