Ultra Low Power Mode

In Ultra Low Power Mode (ULPM), the FX30S application processor and WWAN
radio are off.
The low power micro-controller monitors the wakeup triggers which are:
• Timer (The timer wakeup must be configured prior to the gateway entering
ULPM.) You can use the Legato Timer API or the Legato Power Management
tool (pmtool) command to configure wakeup from ULPM.
• Digital Inputs IO1 and IO2 (IO wakeup must be configured prior to the
gateway entering ULPM.) You can use the Legato Power API or pmtool
command to configure wakeup from ULPM.
FX30S can be put into ULPM using the "pmtool shutdown" Legato command or
the Ultra Low Power Mode Legato API.
Typical wake-up time before network attach is 15 seconds.

Active Mode

In Active mode the FX30S application processor is running and the modem is
operating in one of the following modes:
• Full function—The application processor is fully functional and the WWAN
radio is on; the GNSS radio can be turned on/off.
• Idle—The application processor is fully functional and the WWAN radio is on.
The module is registered on the network, but there is no active connection;
the GNSS radio can be turned on/off.
• Airplane mode—The application processor is fully functional and the WWAN
radio is off; the GNSS radio can be turned on/off. By default the GNSS radio
is on.
Depending on the application, you can lower power consumption by disabling the
Ethernet interface and GPS bias using GPIO52 and GPIO55 respectively. (See
Table 3-10 on page 59.)
