3.6.3 Idle power save
When Idle power save is selected in the web interface and the Idle time has run out,
the terminal deregisters and gracefully closes down the terminal to save power.
Note
To use the Idle power save mode you must configure one or more "wake-up" methods
and a few general settings:
Wake-up methods:
• Daily wake up: Set a time of day where the terminal will wake up
• Wake-on-LAN: Set up the terminal to wake up when it receives a "magic packet" on
the LAN interface.
• Power control pin: Set up the terminal to wake up when the Power control pin is
active. See the following section Power control pin function when Idle power save is
selected. (Note that with AT commands you cannot configure this wake-up method
for Idle power save).
General power save settings:
• Idle time - Set the number of minutes without any activity before the terminal
enters power save state.
• Set whether or not the power save function should be prevented when a satellite
connection (PDP context) is open (only configurable with web interface).
You can configure the wake up methods and the general power save settings in the
web interface under Advanced > Power control. See Power control on page 4-42.
For configuration with AT commands, see the section To set up power save functions
with AT commands on page 3-22.

pin in the web interface.
Disabled: If the Power control pin is disabled, the state of the pin is ignored.

You can set the polarity of the Power control pin, that is whether the pin should be
