APC9212 Device Manager Empty P+ N+ A-

[Anonymous user]

I bought a second-hand APC9212 for £80. Unfortunately, it seems to go into a braindead mode after I supply input power. It cycles on and off several times and then sits forever with no power to the outlets. I found this previous post, but all the links are dead, and seemingly no one knows how to help them,

Below is all the debug output I can think to attach. Do I have any change of rescuing this device? I understand A- means a checksum issue, but I don't know what to do about it. The manuals also offer no guidance for this problem.
