Power-saving
There are two methods to save power in the EXPLORER 540.
•Sleep mode
•Power save mode
Sleep mode
When in sleep mode the terminal is registered, attached and capable of exchanging data
between the LAN and the BGAN satellite interface.
The system enters sleep mode whenever possible, i.e. if it is not active and not in power save
mode.
Power save mode
In Power save mode, the terminal deregisters and gracefully closes down the terminal to save
power.
To use the Power save mode you must configure one or more “wake up” methods:
•Wake up on daily basis
Wake up on input pin (dedicated I/O pin)
General power save settings:
Set the number of minutes without any activity (Idle time) before the terminal enters
power save mode
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 also configure the wake up methods and the general power save settings in the web
interface. See Power save (Settings) on page 71.
To set the idle time before power save
If you are using Power save mode and none of the conditions that prevent Power save mode
are present (mentioned in the note above), the system will go into Power save mode after a
defined idle time.
The following conditions will prevent the terminal from entering Power save mode:
The web interface is open
Data/SMS traffic
•Software update ongoing
Incoming/outgoing calls
Wake up input pin (GPI-1) active
If the Idle time is set to “0”, the Power save function is disabled!
