Gang, I am wondering if you can help? I recently rebooted a 7921 PDU running 3.9.2. The PDU has been happy for as long as I can remember had has been rebooted many times. However upon this reboot the PDU isnt showing any outlets under the device manager.

I cant access the web interface it says something went wrong however I can telnet and serial console to the appliance.

The 7 segment display doesnt light and the led above it is red from the moment of power on.

Does anyone have any ideas ?

Many thanks in advance

It sounds like the firmware is corrupt, I'd try reapplying and seeing if it comes back.
