3 System Installation Specifications for NS2100 Systems
This section provides specifications necessary for system installation planning for an NS2100
commercial system.
NOTE:
All specifications provided in this section assume that each enclosure in the modular
cabinet is fully populated. The maximum current for each AC service depends on the number
and type of enclosures installed in the modular cabinet. Power, weight, and heat loads are less
when enclosures are not fully populated.
Modular Cabinets
The modular cabinet is a EIA standard 19-inch, 36 or 42 U rack for mounting modular components.
The modular cabinet comes equipped with front and rear doors and includes a rear extension
that makes it deeper than some industry-standard racks. The
“Power Distribution for NS2100
are mounted along the rear extension without occupying any U-space in the
cabinet and are oriented inward, facing the components within the rack.
NOTE:
For instructions on grounding the rack, ask your Hewlett Packard Enterprise service
provider to refer to the instructions in the
HPE Intelligent Rack Family Options Installation Guide
.
Power Distribution for NS2100 Systems
This subsection describes these power distribution topics:
•
“Power Distribution Units (PDUs)” (page 44)
•
•
“PDU Strapping Configurations” (page 57)
•
“Uninterruptible Power Supply (UPS)” (page 58)
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 an NS2100 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.
