4 System Installation Specifications for NS2300 Systems
This chapter provides system installation planning specifications for an NS2300 system.
NOTE: All specifications provided in this section assume that each enclosure in the modular
rack is fully populated. The maximum current for each AC service depends on the number and
type of enclosures installed in the modular rack. Power, weight, and heat loads are less when
enclosures are not fully populated.
Racks
The rack is an EIA standard 19-inch, 42U or 36U rack for mounting modular components. The
rack comes equipped with front and rear doors and includes a rear extension that makes it deeper
than some industry-standard racks.
“Power Distribution Units (PDUs)” (page 30) 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 refer to
the instructions in the:

Power Distribution for NS2300 Systems
Power Distribution Units (PDUs)
Two PDU cores provide power for the rack. They mount at the lowest possible U location in the
rack. Both PDUs are mounted in the same U location—one mounted to the rear mounting rail
and one mounted to the front mounting rail.
There are two types of PDUs available for a NS2300 system: Intelligent PDUs (iPDUs) and
Modular PDUs.
Both types of PDUs use a core and extension bar design. Each PDU core supplies power to
extension bars on the sides of the rack. The rear-mounted PDU core connects to the extension
bars on the right rear side of the rack; the front-mounted PDU core connects to the extension
bars on the left rear side of the rack. If the rack is equipped with a UPS, the UPS connects to
the front-mounted PDU core.
The following illustrations show the connections between the PDU cores and the extension bars
using a 42U rack as an example.
NOTE: These illustrations are not an exact visual representation of the rack. To show the
connections clearly, the rear-mounted PDU is shown outside the rack with its outlet side showing.
The rear PDU is actually oriented with the breaker side facing outwards. The locations of the
extension bars might not exactly match your installation.
