Remedy
Check your computer configuration:
If the computer configuration corresponds to the delivery
•
state, contact your technical support team.
In the case of a change in the configuration, restore the
•
delivery state. To do this, remove the expansion card and
restart the device. If the error no longer occurs, the expan-
sion card was the cause of the fault. Replace this with a
Siemens expansion card or contact the supplier of the ex-
pansion card.
If the device still crashes, contact your technical support team.
Use a powerful 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.
