Hardware Power Switch
The power switch located at left side of the main unit is a slide type
switch. This switch controls the power on/off of the system. This switch turns
the system on when slid downward, only when external power is present. The
switch will always spring back to its original position when pressure is
removed. This switch turns the system off when slid downward again during
power on status. However, if the system hangs due to any reason such as
software resource conflict a simple slide of the switch may fail to turn off the
power. In this case, please utilize the forced power off feature by pressing the
switch downward, and holding for within 10 seconds. In case the turmoil is so
vigorous that some hardware registers may be confused causing trouble for
system restart or even this forced power off, please disconnect the UPS battery
if installed and the AC power supply for few minutes. This may allow all
hardware registers to reset.
This switch can also be programmed as an ON only switch. That
means, if the application program issues a command compliant with the Jiva
series technical manual, this switch will always turn the system on when
activated, but will not power off the system when depressed again (the forced
power off feature will not work in this mode). When using this feature, please
make sure that the software application has the ability to power off the
machine. In preloaded Windows, “Posiflex Power Switch Manager” in
“Posiflex Tools” in the Program Files helps managing these functions.
Software Support Features
The Jiva series provides a software power off command for
application program maneuvers. The Jiva also provides a specific means for
the software to detect if the system is working on external or UPS battery
power. Due to this feature, compatible software applications have the ability to
change operating conditions when running on standard/backup power. The
software programmer may take reference from the Jiva technical manual to
apply such features.
