3-6. Shutdown switch
The shutdown switch is used when the OS or application programs
are straying and the system can not return to the normal state.
You must not use this shutdown switch when the UP-5300 is running
normally. Use this switch only when the main power source is not cut
off even if the main unit power switch is set to OFF position. UP-5300
is turned OFF and the hardware is reset by turning the main power
switch OFF and then pressing the shutdown switch.
[Out line]
The shutdown switch is single shot type. (Normally OFF position)
Push ON:
This position is used to reset stand-by mode for power
supply unit when software hang up.
Release OFF: Usually the shutdown switch needs to be set to this
position when the UP-5300 is operated.
[Operating method]
The shutdown switch is a push switch. If it is pushed to ON, the
UP-5300 stops supplying the power when the power switch is set into
stand-by mode.
NOTE: The shutdown operation will be ignored when te power
switch is set into power-on position.
3-7. System switch
The system switches are used to preset various system configura-
tions.
[Out line]
The system switches consists of DIP switches.
[DIP switch]
The PSC2 simply reads the switched signals from the DIP switch as
hardware. The meaning of the switche settings are shown on the next
page.
