For instructions on grounding the modular cabinet's rack by using the HPE Rack
Grounding Kit (AF074A), ask your Hewlett Packard Enterprise service provider to refer to the
instructions in the
HPE Intelligent Rack Family Options Installation Guide

Each PDU is wired to distribute the load segments to its receptacles. For more information, see
“Power Distribution for NS2100 Systems” (page 44)
. Factory-installed enclosures are connected
to the PDUs for a balanced load among the load segments.
CAUTION:
If you are installing NS2100 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
The total power and current load for a 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, see
“Calculating Specifications for Enclosure Combinations” (page 71)
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.
