CI853 'device not found' & PM864 failure
We're running a redundant PM864 CPUs with CI810 and CI853 modules on the CEX bus.
We had a 'Device Not Found' error on an CI853 Modbus module after the card was swapped under power.
Later the Backup CPU went to fault with a message 'Modulebus clustermodem error' and all atempts to Cold Restart it by INIT failed (the CPU would restart and sync to DUAL mode then fail again).
I suspect the CPU failure has to do with the Modbus card error and should be cleared once we get that solved. Is this correct or is it another issue?
Is there a way to resolve / clear these errors without a complete Restart of redundant controllers (both of them)? We cannot go for downtime on this application now and are running with single controller.
Please see attached for error messages.
Hello pls explain on ur system config like are using bc810 and redundant ci853 else please provide the full log details under remote system -system log to understand better.
Which system version its running?
Ci853 modbus RTU module is not hot swappable means don't remove it in online, so removing and inserting module will not detect in the CBM and backup controller went fault mode may be particular module bus line tb840 fuse blown r tb840 is removed so u have to reset the controller to get back in line
