3.4 Compatibility of OSM Version 2/ESM with OSM/ORM

Version 1

Compatibility

Version 2 OSMs can be operated at the same time in the ring with the OSM (6GK
1105-0AA00) and ORM (6GK 1105-1AA00) here called OSM/ORM Version 1.
Make sure that only one device can adopt the redundancy manager function in the
ring; in other words, only one ORM or only one OSM Version 2 operating in the RM
mode.
