The netbooter can power-cycle the drive and CPU (PXI), not all cabinet.

Restarting the EUI worked and the Statemachine transitioned to Enabled state.
However after ~4days of resting with the emergency stop pressed.
– the EUI did not permit to clear the fault after the emergency stop was released
– the low-level controller was unresponsive, Te-Wei Tsai helped but the low-level controller could not be reset by software.
– the hexapod cabinet needed to be restarted using the netbooter to solve the problem.
