Servers of 800xA, AC450 PLC
What are the consequences of switching off any of the 800xA servers while line is running? I did this because one of HMI's was hanging and after resarting it, it become ok.

It depends on your existing system configuration.
if you have redundant servers, you can restart one of your server (Aspect or connectivity) provided that its redundant server is running and showing healthy status.
More Details of your system configuration might help us to comment.
Which server you want to switch off and why ?
If you maintain CPU load trend logs of the AC450 and/or RTA and can backtrack to the event and notice increased CPU load in controller and/or RTA until the restart, its likely due to the known error.
Please contact your regional ABB support center for further assistance with verifying patch availability.
