Each PDU is wired to distribute the load segments to its receptacles. For more information, see
“Power Distribution for NonStop NS2400 Series Systems In Intelligent Racks” (page 52).
Factory-installed enclosures are connected to the PDUs for a balanced load among the load
segments.
CAUTION: If you are installing NonStop NS2400 series system enclosures in a rack, balance
the current load among the available load segments. Using only one of the available load segments,
especially for larger systems, can cause unbalanced loading and might violate applicable electrical
codes. Connecting the two power plugs from an enclosure to the same load segment causes failure
of the hardware if that load segment fails.
