AP9641 Not booting

[Doug66]

We have a new AP9641 and it will not boot.  We set it up just like the others we purchased, but after reboot, it will not boot.  Can get into the BM mode and get the following:

BM> mfginfo

======== Mfg Information ========
Mfg data is invalid!

BM> sysinfo

Thanks in advance for any help.

I have run into this once or twice. the issue is something did not transfer right during the upgrade process. Or some old setting is not working right with the new firmware.

In BM mode you should have the command "factory_reset" Initiates a complete reset of the file system (this functionality is equivalent to the format command. and should restore the card to working order, or at the very lest enough to get to the FTP prompt to upload the missing file

After issuing the above command you must enter "factory_reset_confirm" to confirm the reset to factory default settings.

https://www.apc.com/us/en/faqs/FA293874/ has a list of all commands that you can use in BM mode.
