What is the correct 3.3V Power Budget for the BMXCPS4002(S) power supply?

There is a power supply specification conflict between a reference manual and Control Expert software.

According to the x80 Power Supplies and Racks Hardware Reference Manual, (part number EIO000000262), the BMXCPS4002 (and S) power supply provides 5A on the 3.3V backplane bus.  Control Expert V14.1 shows that 5.5A is available on the 3.3V bus.

Product Line

Control Expert V14.1

They are both correct as:
  • 5A is the nominal value for the 3.3V bus.
  • 5.5A is the maximum value for the 3.3V bus.

This will be clarified in future documentation.
