Power switch operation
During normal operation, the power switch on the SurePOS 700 Series operates as
you would expect. Push the switch to turn on the system; push it again to turn off
the system with the following exceptions:
v
You can program the switch to operate differently. For example, if your operating
system supports power management, you can program the switch to behave as
a standby or resume switch. For more information, refer to the documentation
included with your operating system or power management software.
v If you press the power button when the unit is running its power-on self-test
(POST), a delay can occur when you are turning the system off.
v
Sometimes you cannot initiate a controlled shutdown because the application or
system is hung. Press and hold the power switch until the unit turns off
(approximately 5 seconds).
Note: Pressing and holding the power switch to shut off the SurePOS 700 is not
recommended. Use this method only when no other method is available to
turn off the system. If you turn off the unit by pressing and holding the
power switch, some programmed events do not function until the unit is
turned on again (for example, IBM Wake on LAN).
Power management
Power management on the SurePOS 700 is based on the standard desktop PC
model. Depending on the operating system and drivers that are used, all models
are capable of being placed into a standby state with AC power applied. Refer to
the
IBM SurePOS and AnyPlace Power Management Configuration document
located on the POS Knowledgebase, http://www.clearlake.ibm.com/store/support/
html/knowledgebase.html, for more detailed information. Protection from AC power
events is provided by an optional uninterruptible power supply that can be
integrated into the wide-footprint unit.
Support is provided for the following industry standards and conventions:
v Advanced Configuration and Power Interface (Models xx3 and xx4) (ACPI)
v
Advanced Power Management (Models xx3) (APM)
v Wake on LAN
v
Wake on USB
v Wake on SIO/RS-485
v
Wake on PS/2 keyboard/mouse
v Wake on real-time clock alarm
Note: Device and system standby is not supported for Advanced Power
Management.
Uninterruptible power supply (optional)
The technical characteristics of the uninterruptible power supply are as follows:
v Capacity: 500 VA/300 W
v
Run time: 2.5 minutes minimum at full-rated (500 VA) load with a new, fully
charged battery
v Output voltage in battery mode: 113 VAC ±10% for low range; 220 VAC ±10% for
high range
