Each onboard FPGA Logic regulator can be disabled by using its respective Power
Regulation jumper (callout 17,
moving its Power Regulation jumper from POR_B to RESET.

Monitoring Voltage and Current
Voltage and current monitoring and control are available for FPGA logic and transceiver
power rails through Texas Instruments' Fusion Digital Power graphical user interface
(GUI). The three onboard TI power controllers (U9 at PMBUS address 52, U10 at PMBUS
address 53, and U11 at PMBUS address 54) are wired to the same PMBus. The PMBus
connector, J26 (callout 20,
