Best practices guidelines
To ensure optimal operation of your system, always follow these best practices guidelines:

Similarly, the right and left power supplies of the DS4000 storage expansion enclosures attached to the DS4700 Express should be plugged into the same two independent external power circuits as the DS4700 Express. This ensures that the DS4700 Express and all its attached storage expansion enclosures will have power in the event that only one power circuit is available. In addition,
