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.
