3 NS7 System Installation Specifications
This chapter provides specifications necessary for system installation planning. All specifications
in this chapter assume that each enclosure in the rack is fully populated. The maximum current
for each AC service depends on the number and type of enclosures installed in the rack. Power,
weight, and heat loads are less when enclosures are not fully populated; for example, a SAS
disk enclosure with fewer disks.
Racks
The rack is an EIA standard 19-inch , 36U or 42U rack. The rack comes equipped with front and
rear doors and includes a rear extension that makes it deeper than some industry-standard racks.
The PDUs described in
“Power Distribution Unit (PDU) Types for a Rack ” (page 24) are mounted
along the rear extension without occupying any U-space in the rack and are oriented inward,
facing the components within the rack.
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 see the
instructions in the:

Power Distribution Unit (PDU) Types for a Rack
The Enterprise series rack (formerly known as the Intelligent rack) supports Intelligent PDUs
(iPDUs) and Modular PDUs. Both PDU types use a core and extension bar design with these
characteristics:
•
PDU cores power the extension bars and c7000 enclosure.
•
PDU cores are mounted at the lowest possible U location in the rack. Two PDUs are mounted
in the same U location (rear and front).
•
Extension bars are mounted on the rear vertical rails of the rack.
•
Rear-mounted PDU cores connect to the extension bars on the right side of the rack.
•
Front-mounted PDU cores connect to the extension bars on the left side of the rack.
•
If the rack is equipped with a UPS, the UPS outputs connect to the front-mounted PDU
cores.
NOTE: A rack with a c7000 enclosure requires a four PDU core configuration. Racks without
a c7000 enclosure use a two PDU core configuration.
