CAUTION: If you use the Redundant Power System, do not use the AC power
plug on the rear panel or the AC power cable that is supplied with each hub.
Instead, use the RPS cable and insert one end into the RPS and the other into
the DC input connector on each hub. If you do not use the RPS, you must
connect each hub separately to an AC power source.
