2.2. Power-on, on/off and reset signals

You can use either of the push buttons to reset the system, but only the ON/OFF push button can power-up the system. The motherboard drives two reset signals to each daughterboard and receives a reset-request signal from each daughterboard.

Figure 2.2 shows the power-on ON/OFF/Soft Reset push button and Hardware RESET push-button signals in the system.
