MX471 CAN channels potential issue. There is the following known issue with using MX471 CAN channels in a CX23R test. Sometimes the test will fail to start on a "Timeout waiting for (MX471) channel ready announcements" error and the system will reset. In almost all cases, the test will restart properly after the system reset. We have never seen this issue on a power cycle test restart so that's the last resort for getting a test to run if it does not start on the error reset.
EX23-R PTP Synchronization with MX modules using ports 5 and 6. Using a system connected with MX modules connected to ports 5 or 6 on the EX23R can rarely result in the MX modules losing sync with the CX23R until the EX23R is rebooted or power cycles. This has only been encountered in QA testing a few times and only when the system has been running for relatively long periods of time (e.g., over a week). However, this can be very problematic for long term unattended testing - particularly in scenarios where power is never cycled. As such, it is strongly advised that MX modules are not connected to ports 5 or 6 in long term unattended tests. Network sources such as Axis cameras can be connected to port 6 (or port 5 when routed through a commercial PoE switch).
