AP7953 Firmware Upgrade

[johnoatwork]

Hi Community, 

I upgraded the firmware on a AP7953 PDU using "apc_hw02_aos390_rpdu374.exe" that I found on se.com. The app said the upgrade completed successfully but I was getting kicked out of the web interface after about 30 seconds so something was wrong (wasn't doing this before the upgrade). 

I had another try with the same version of the firmware and it failed so I then tried with "apc_hw02_aos392_rpdu392.exe" that I downloaded from this forum. Looking at results.txt it looks like the firmware is corrupted (extract below).

I can still telnet to the device, but as with the web interface get kicked out after a few seconds. Stat reads P+ N+ A+ which I understand means things are OK (not!)

I've tried resetting to defaults and anything else I could think of but not luck.  I'd appreciate any tips or advice on how to resolve this.

Thanks

John
