Tried to downgrade (dont ask) a 403 to 3.0dt. used at-x3 etc as per manual. All settings are correct. Looking at tftp log manager gets a bootp request, it sends a bootp response and then it says unable to send c:\programfiles....\p2.bin??? Nowhere can I find a p2.bin file. I suspect the unit needs to be sent off for repair as the only time I have seen p2 is in the hyperterminal session ie "P2 Loader 0.9" on a reboot. Any help would be much appreciated
