6.4.2
Messages after replacement of DRIVE-CLiQ components
After DRIVE-CLiQ components are replaced (Control Interface Module, TM31, SMCxx) when
service is required, generally no message is output after power-up, since an identical
component is identified and accepted as component when the system boots.
The reason for this is that an identical component is detected and accepted as spare part
when running-up. If, unexpectedly, a fault message of the "topology fault" category is
displayed, then when replacing a component, one of the following faults/errors should have
occurred:
•
A Control Interface Module with different firmware data was installed.
•
When connecting-up DRIVE-CLiQ cables, connections were interchanged.
