How add third server in 800xA
Installation User's Guide, on 5.1 media.
Another, unorthodox, unsupported method is cloning one of the other aspect servers. Hardware must be same for this to work.
- Clone existing server

- Join domain
- Apply System Software User Settings

The original concept of 2oo3 redundant AS was part of the early release of 800xA. Generally, with a Version 4 system onwards 2oo3 Redundancy is not required and does not give a significant increase in reliability. Hence, 2oo3 systems are normally only used on large projects, where the AS are physically distributed and where the is some expectation that an AS could be lost during project engineering.
A small system of 2 Servers and 2 clients, already installed in a running plant, is not usually a candidate for 2003 redundancy.
What are you trying to achieve ?
but I can not find documents how configure Auxiliary Client and what about dongle (hardware key) ?
I have dongle If I make 2or3 system my dongle will be enough? System continue work properly?
