Best practices guidelines
To achieve optimal system operation, always follow these best practices guidelines:
v Make sure 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 DS5020 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, make sure that the right and left power supplies of the storage
expansion enclosures attached to the DS5020 are plugged into the same two
independent external power circuits as the DS5020. This ensures that the
DS5020 and all its attached storage expansion enclosures will have power in the
event that only one power circuit is available. In addition, having all the right or
all the left power cables plug into the same power circuit enables the devices in
the configuration to power on simultaneously during an unattended restoration of
power.
