Best practices guidelines
To ensure optimal operation of your system, always follow these best practices
guidelines:
v
Ensure that your system is in an optimal state before you shut it down. Never
turn the power off if any Needs Attention LED is lit; be sure to resolve any error
conditions before you shut down the system.
v Back up the data on your storage drives periodically.
v
To maintain power redundancy, plug the DS4700 Express right and left power
supply and fan units into two independent external power circuits through ac
power distribution units inside a rack cabinet or directly into external receptacles.
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,
