Power mode functions

Power control pin is inactive:
The terminal will attempt to go into power save state.
However, a number of conditions may keep the terminal awake even if the Power control pin is
inactive:
• Optional shut-down delay period ongoing.
This is a configurable delay period between deactivating the Power control pin and entering
power save state.
• The terminal is in the process of updating software or downloading software for installation.
• The terminal watchdog is executing.
• Optional daily awake period ongoing.
This is an optional configurable period of time that the terminal should stay awake every
day.
• Terminal was started by connecting power and 3 minute grace period is still ongoing.
To avoid the terminal going into power save state immediately at power-up, the terminal
stays awake for 3 minutes after power-up, to allow for reconfiguration of the terminal if
wanted.
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.
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).
Note
The terminal is considered active (
not idle
) if one or more of the following
conditions are present:
• The web interface is open.
• Data or SMS traffic.
• Software update ongoing.
• Incoming/outgoing calls.
• Terminal watchdog executing.
• The terminal is started by connecting power and the 3 minute grace period is still
ongoing.
• One of the configured wake-up methods are active (see below).
