BC820 - online replacement
Except max cable distance of 200 m what are advantages of BC820 over BC810?
What is replacement procedure of one BC820 in redundant configuration ?
the purpose of using BC810/BC820(long distance-200m with 50/125um fiber) is to separate the CEX bus into two physical segments so that faulty controller with Baseplate can be replaced online one by one without disturbing the entire running str.
The online replacement of BC810 in running system is not supported till 5.0 but if the hardware product version supports for online replacement.
There are 2 scenarios:
1.replacing Direct/Indirect BC810/820 will not be possible online since BC acts as interupts it will jeo-pardize the entire running system hence replacement of BC possible only when entire node is down.
2.Replacing Indirect BC can be done online without disturbing the BC810 with RCU cable on the Primary/upper segement by switching off adjascent CPU power also(must) (means BC with primary PM can't replaced online needs node shutdown)
