Part 16
FAN CONTROL
In the preloaded OS for this HT system, there is an embedded
function that can keep on monitoring the interior temperature and the fan
revolution rate and regulating each required fan power to gain maximum
ventilation effect with lowest possible noise. This function is disabled by
default at delivery. The user can decide to engage this function by clicking
“Start” --> “Programs” --> “Posiflex Tools” --> “Posiflex Fan Control” to pop
up a window like the right picture. Click
“Enable” then “Apply” to engage this function
in background. This function will remain
operating even after system restart. To disable
this function, you have to pop up this window
again and click “Disable” then “Apply” and
restart the system. If system hang due to CPU
overheat occurs, please
review the ventilation
condition and environment temperature, check if
the fan is stuck by contaminants such as dry grease or threads and try to correct
the situation when the system is off and cooled down. You may power up the
system again after the system cooled down and trouble cause removed.
However, if the trouble remains, please consult your dealer for possibly fan
replacement on worn out.
USB
There are in total six standard USB female connectors in the rear
room. All support the Universal Serial Bus Specification standard 2.0 and also
1.1. If for any reason (though very unlikely in ordinary practice) these ports
has to be limited as USB 1.1 only, please enter BIOS setup and go to
“Integrated Peripherals” then “SiS OnChip PCI Device” and disable the item
“USB 2.0 Supports”.
One among the six USB ports can be extended to top edge of system
unit for the side-mount upgrade kit by a cable.
