Power Modes

The FX30S is designed to handle extremely low power. It has three power modes:
•
•
•

OFF Mode

In Off mode, the FX30S application processor, WWAN radio, and low power micro-
controller are off. On/Off is controlled by Pin 3/GPIO24 (On/Off) and GPIO58 (Power
Hold).
If no Legato applications are in place for GPIO58 (power hold), the gateway is off when
Pin 3 is low and on when Pin 3 is high. Note that the GPIO24 input signal is inverted
(Pin 3 low = GPIO24 high, Pin 3 high = GPIO24 low).
However, the power line from Pin 3 is also connected to GPIO58 (power hold). GPIO58 is
low by default. If either Pin 3 or GPIO58 is high, the gateway is on. GPIO24 monitors
Pin 3. (See
detects when Pin 3 goes low, and holds the power on temporarily to complete the desired
actions prior to the gateway turning off, for example, a graceful shutdown process or a
"last-gasp"-type feature.
