PM 861 A synchronising issues
I am new to 800 M processors. So, kindly help me out in this basic issue. I have two PM 861 - A processors. CEX and RCU link cable is connected between two 861A processors. Inorder to check if secondary/down CPU has ip address, the foll is done :
1) IP is typed in run command and continously pinged.
2) Primary/Upper cpu is switched off. The secondary/down cpu automatically switches over to primary.
But there is no reply from the processor. Does this mean that the secondary/down cpu doesnt have the ip address?
After this i recycle the power for both the processors. The secondary/ down cpu goes to fault mode. In the controller log file i dont see any fault message. The last message in the log file is " Firmware not upgraded". When the power is switched off for some time (prob : 10 min) and switched on again, both the processors go to run mode and prim/sec indication glows in the cpu. Whats the reason for recieving fault indication ?
Generally Secondary Controller IP address will be taken as 0.0.2.0 by default rule with respect to Primary Controller.It is not the same as Primary Controller IP address.
You need to contact supportline and share controller logs to know why the secondary controller went to fault mode.
Also refer AC800M configuration manual to understand more on controller log messages.
We had identical problem with PM865 at our site here. This controller going into fault means that it is not identifying other controller.
We went through following steps and got rid of problem
1. Put upper CPU on primary and update firmware.
2. Put lower CPU on primary and update firmware again.(It is very important for firmwares to be updated)
3. Do the IPConfig after that.
we have rectified many configurations by doing thee basic steps.
But if still it persists,
Pl do check that
1.Weather BC810 unit is properly functional/Mounted on the bus bars.
2.RCU link cable is appropriate and functional.
In few cases, we have found these problem are also the reason for the same
I hope this works!!!!!!!!
