POWER ON/OFF CONTROL
The HT terminal implements electronic power control, such that the
main power to the system may be controlled by many methods as below:
1. Hardware power switch
2. Software OFF command
3. Automatic power ON control
4. Emergency power OFF
Switching from OFF to ON requires a normal supply of the AC power.
Hardware Power Switch
This button is located at bottom front corner of
right side as in right picture and can be used to turn the
system on and off alternatively. This hardware switch
can also be programmed to be an ON only switch
through software command so that when this switch is accidentally pressed
during system turned on, the system just remains on and unaffected.
Software Off Command
The system may also be shut down under software control. Please just
follow the arrangement by your system integrator for this capability.
Automatic Power On Control
The system may also turn on according to some preset conditions
such as Modem Ring Up and Alarm Clock Wake Up or LAN Wake Up.
To utilize Modem Ring Up or Alarm Clock Wake Up function, the
user should enter the CMOS setup by pressing “Del” key at system boot up,
choose for “PM Wake Up Events” in “Power Management Setup” and make
the “Ring Power Up Control” enabled for Modem Ring Up or select the
“Power Up by Alarm” for Alarm Clock Wake Up. Save the configuration and
exit the CMOS setup program. The Preset Power On Control will then be
ready after a normal power off. For LAN wakeup, an operating caller system
connected through LAN to the system is required. It also requires a qualified
networking technician to check the LAN chip ID of the HT system for the
caller system to wake it up.
When the HT system is turned off after a successful boot up, the
preset automatic power on functions will keep monitoring for the preset
conditions and turn on the system when the preset conditions are met.
Please note that if the HT system is improperly turned off before a
complete boot up procedure, the above preset power on control functions will
be disabled until next turning off after a complete boot up.
