Board 48V 13.5V
Board 24V 6.7V
Board 3V 0.3V
This seems like a reporting problem, as the switch operates normally. Any suggestions?
Questions:
1) Are you using SFP modules? Since the I2C bus is shared with the sensors some SFP modules will cause I2C errors. Simply unplugging and plugging back in will resolve or maybe try another model SFP. It is easy to tell by simply removing module and see if issue goes away.
2) Can you reboot the device and see if the problem goes away?
The only other reason I have seen voltages reported wrong was a damaged board but you say the voltages were correct before upgrade HOWEVER we were not making them obvious when they were out of range in previous firmware so they may have been wrong before you upgraded the switch and never noticed?
