Problems when using 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 expansion 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.
Insufficient output of an external
power supply, e.g. UPS
Use a powerful power supply.
The device does not start up
or switches off immediately
A counter voltage is fed into the
device by connected or installed
expansion cards
Clarify the following with the supplier of the compo-
nent:
•
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.
