I have the same issue
I have 2 x datacenter, one principal in Lisbon and the fail over in Oporto, 380km away.
The main datacenter is in Lisbon they have all main services there, with dedicated fiber connection, fixed IP, MPLS, etc…
The datacenter in Oporto it’s replicating all the information from lisbon.
When connection fail in lisbon, the operator change the fixed IP to Oporto, and all the information is established there in failover.
If I put both UCM65xx and HA100 only in lisbon, and if the p.ex. the internet system fails, I’m going to be unconnected, because I have all connections servers and bothe UCM’s and Ha in the same dataceter! So I need to have one of the UCM’s in the other Datacenter in Oporto and HA too.
How can I solve this ?
Is it possible to do this with a RS485 - ethernet converter ?
