There are some limitations when using computer cabling redundancy that you need to be aware of before you implement it.
Functionality Limits
The following functionality limitations apply for Computer Cabling Redundancy:
If you are viewing logged
data remotely with the Trend Control and the Ethernet cable that
ODBC is currently using is lost then the Trend Control will stop
updating the logged data.
If you are logging to a
remote database and the Ethernet cable that ODBC is currently using
is lost then some data may not be logged.
Non-CIMPLICITY applications
might experience interruptions as they fail over to the remaining
Ethernet cable.
It is not possible to have
two Ethernet cards installed and only use one of them for
CIMPLICITY software.
Failure Recovery Limitations
CIMPLICITY Computer Cabling Redundancy will not cover the following failures:
Loss of both network
connections.
Rapid, alternating loss of
both network connections, where the time period is less than 45
seconds.
