Enclosure AC Input
NOTE: For instructions on grounding the Enterprise series rack (formerly known as the Intelligent
rack) using the HPE Rack Ground Bonding Kit (BW891A), ask your service provider to refer to
the instructions in the:
•
HP Rack Options Installation Guide
•

Enclosures (blade element, VIO enclosure, and so forth) require:
Value Specification
200/208/220/230/240 V AC RMS Nominal input voltage
180-264 V AC Voltage range*
50 or 60 Hz Nominal line frequency
47-53 Hz or 57-63 Hz Frequency ranges
1 Number of phases
* Voltage range for the VIO enclosure is 100-240 V AC, and for the maintenance switch is 200-240 V AC.
Each PDU is wired to distribute the load segments to its receptacles. For more information, see
“Power Distribution for NS2300 Systems” (page 30) . Factory-installed enclosures are connected
to the PDUs for a balanced load among the load segments.
CAUTION: If you are installing NS2300 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.
Enclosure Power Loads for NS2300 Systems
The total power and current load for a rack depends on the number and type of enclosures
installed in it. Therefore, the total load is the sum of the loads for all enclosures installed. For
examples of calculating the power and current load for various enclosure combinations, see
“Calculating Specifications for Enclosure Combinations” (page 55) .
In normal operation, the AC power is split equally between the two PDUs in the rack. However,
if one of the two AC power feeds fails, the remaining AC power feed and PDU must carry the
power for all enclosures in that cabinet.
Power and current specifications for each type of enclosure are:
