A.4 Notes on the use of expansion cards
Problem Cause Remedy
The device
crashes during
startup
•
Redundant I/O addresses
• Redundant hardware interrupts
and/or DMA channels
•
Signal frequencies or signal
levels are not adhered to
• Different pin assignment
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.

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.
