Voltage range for the maintenance switch is 200-240 V AC.
Each PDU is wired to distribute the load segments to its receptacles. Factory-installed enclosures
are connected to the PDUs for a balanced load among the load segments.
CAUTION: If you are installing Integrity NonStop NS16000 series system enclosures in a modular
cabinet, 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
The total power and current load for each modular cabinet 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, refer
to “Calculating Specifications for Enclosure Combinations” (page 62).
In normal operation, the AC power is split equally between the two PDUs in the modular cabinet.
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.
NOTE: If your system includes the optional rackmounted HP R5000 UPS, the modular cabinet
will have one PDU located on the rear left side and four extension bars on the rear right side. To
provide redundancy, components are plugged into the left-side PDU and the extension bars. Each
extension bar is plugged into the UPS.
