WARNING: To avoid possible injury, damage to storage server equipment, and
potential loss of data, do not use the surplus power outlets in the storage server
PDUs. Never use outlets in the PDUs to power components that do not belong to
the storage server or to power storage server components that reside in other
cabinets.
