Client as Standby Server

Client as Standby Server

Hello,
I am working on a substation automation project.
We have one Substation where there is 1 Client. (this client has zenOn EE Server License). (We are using IEC61850)
We have one CCR where we have 2 x Servers i.e, Server 1 and Server 2.
In the Project Network Settings I have defined Main Server = Server 1 and Standby Server = Server 2.
If Server 1 fails then client in the Substation is connected to Server 2 (Standby Server).
I would like to know is it possible that Client in the substation also act as Standby Server if Server 1 and Server 2 in the CCR fail?
If yes, how can we achieve this?
I would also like to know how the redundancy of Main Server and Standby Server is working in zenOn? Do both of these Servers are connected to the Hardware at the same time ?
OR
Standby is only connected to the Hardware when Main Server Fails?
Thanks
