The Current Load reads: 401.17 watts
I thoroughly reviewed the firmware update documentation to insure there were no power-related "fixes". The fixes that are listed in the Release Notes for each update do not appear to offer a related benefit.
We ordered an additional power supply that we will be receiving tomorrow and will subsequently install. We powered off one of the other compute modules and then powered on the compute module we inserted into slot 4 and the compute module powered up and performed its firmware update. We then powered the 4th compute module off and powered back on the compute module we previously powered off. Then we tried to power on the new compute module again without success.
I suppose we will know more tomorrow evening after receiving the new power supply.
Thanks for responding and if you have any other thought as to why this might be occurring, we welcome your input.
