On/Off button
Note
The on/off button is only effective when the power supply is switched on via the
on/off
switch at the rear of the device.
Note
The PC switches on automatically after the power recovers when "Restore AC Power
Loss" is active.
Depending on the
"Restore AC Power Loss" setting in BIOS, the PC switches on automatically
or you must press
the on/off button on the front. The BIOS setting only becomes effective
when the device is without mains voltage for at least 10 seconds.
Automatic startup may endanger the o
peration of the machine or plant, for example, after a
power failure. Take this into account when designing the plant.
The following figure shows the position of the on/off button at the front of the device.
The on/off button ①has three functions:
•
Switch on the PC, press the on/off button once
shortly.
•
Shut down the operating system and switch off
PC, press the on/off button once shortly.1
•
Switch off PC without shutting down the
operating system, press for more than 4 seconds
– hardware reset.
1
You can set this operation as shut down or hibernate in operating system.
NOTICE
Data loss
If the device is restarted by hardware reset, data in the main memory is deleted and the data
on the hard disk drive may be lost.
Perform a hardware reset only in the case of an emergency. Close all running programs.
Make sure that there is no more read or write access to drives and I/O before performing the
hardware reset.

2.1 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed visit (https://www.siemens.com/industrialsecurity).
2.2 General safety instructions
WARNING
The installer of the system is responsible for the safety of a system in which the device
is integrated.
There is a risk of malfunction which could result in death or serious injury.
•
Ensure that only suitably qualified personnel perform the work.
