Hi All,

I wired up our power distribution board based on the wiring diagram in the control system documentation. When I powered on the robot to do our OTB tests, the power distribution board makes a squealing noise and the LED indicating the health of the 5V power supply does not turn on. When I unplug the gateway from the 5V rail the squealing stops.

Can anyone explain why this is happening? Could I have hooked up something wrong? Do I have a defective power distribution board?
