A.3 Notes on the use of third-party modules
Possible remedy
Turn on USB Legacy Support for mouse and
•
keyboard.
For other devices, you need the USB device
•
drivers for the required operating system.
Deactivate the EWF or use an alternative method to
"chkdsk".
Possible remedy
Check your computer configuration:
If the computer configuration corresponds to the delivery
•
state, contact your technical support team.
If the configuration has changed, restore the factory state.
•
To do this, remove the third-party modules and restart the
device. If the error no longer occurs, the third-party module
being used was the cause of the fault. Replace the thrid-
party module with a Siemens module or contact the module
supplier.
If the device still crashes, contact your technical support team.
Use a higher capacity power supply
•
Clarify the following with the supplier of the component:
The component can be operated without an external power
•
supply.
The component can be reconfigured so that it only uses the
•
external power supply or that of the device.
