Idle power save
When you use the AT_IPWSAVSCHD command you set the power save mode to Idle
power save, provided you define an idle time (more that zero) and you define at least
one valid wake-up method.
Important
To set the idle time before power save
If you are using power save mode Idle power save and none of the conditions that
prevent power save state are present (mentioned in the section Idle power save on
page 4-37), the system will go into power save state after a defined idle time. You can
configure this Idle time with the AT command _IPWSAVSCHD as follows:
1. Set the idle time before power save:
AT_IPWSAVSCHD=<psmode>,<psvalue>
Example: AT_IPWSAVSCHD=IDLE_TRG,15
In this example, the power save mode is Idle power save, the trigger is idle time
(IDLE_TRIG), and the idle time before the terminal enters power save state is 15
minutes.
Important
To configure wake up on daily basis
1. Set the time of day that the terminal must wake up from power save:
AT_IPWSAVSCHD=<psmode>,<psvalue>
Example: AT_IPWSAVSCHD=TOD_TRG,24:00
In the example above, the wake-up method Time Of Day (TOD) is selected, and the
time of day to wake up from power save is 24:00 UTC time.
Note
To configure Wake-On-LAN
1. Set the Wake-On-LAN function to On or Off:
AT_IPWSAVSCHD=<psmode>,<psvalue>
Example: AT_IPWSAVSCHD=WOL_STATUS,1
In the example above, the wake-up method Wake-On-LAN is selected. This means the
terminal will wake up from power save when a "Magic packet" is received on the LAN
interface.

If the terminal was already in Idle power save mode before the command
and the Idle time is set to "0" with the AT command below, or you have
not defined a wake-up method, the Power save function is disabled and
the terminal will be always on.
If the terminal was not in Idle power save mode and the time is set to "0",
the parameter is stored, but the power save mode is not changed to Idle
power save mode.
Remember to configure one or more wake up functions - otherwise the
EXPLORER 540 will not be able to enter power save state.
If the wake-up time of day is set to "0" with this AT command, the "Wake up
time of day" function is disabled! You must configure another wake-up
method.
