11 Power Saving Functionality

11.1.5 Cooling fan control (Semi-fanless operation) [AX1240S]

Semi-fanless operation stops the fans in an environment that is determined to be
acceptable by internal temperature monitoring and in which forced cooling of the device is
not required. It also turns on the fans to start forced cooling (semi-fanless operation) when
the ambient temperature is too high. This can prevent noise and reduce power
consumption.
This functionality is enabled by executing the
command. (If this command is not specified, the fans run continuously.)
Conditions that will cause the fans to start and stop when using this configuration command

Start conditions: When an internal temperature of 47 degrees Celsius or higher is
detected

Stop conditions: When an internal temperature of 46 degrees Celsius or lower
continues for 10 minutes after detection
This functionality is supported by the AX1240S-48T2C model only. Even if you start the
device with this functionality enabled, the cooling fans always run for approximately 10
minutes immediately after the device starts.

11.1.6 Power saving scheduling

You can schedule the power saving functionality to run for a specific period of time. For a
schedule, specify a combination of power saving functionalities and the period of time
during which they are to be run. When the specified start time arrives, power control is
initiated automatically. Once you have scheduled the power saving functionality, you can
also disable it for a particular period. A set period when power control is enabled is referred
to as a scheduled time range and a time when power control is not enabled is referred to as
a normal time range.
