I have found that EMC documenation can be hard to find it when you need it, ( at least from a public side ) and therefor, I thought I’d post this.

Not only can adhering to their standards, improve peroformance, but it can also provide for a more stable and less problematic system.
Please Refer to the full post for the configuration recommendations.
