NonStop NS2400 Series Planning Guide

for other HP hardware that will be installed at the site with the NonStop NS2400T and NS2400ST
systems, consult with your HP account team. For site preparation specifications relating to hardware
from other manufacturers, refer to the documentation for those devices.
Component Location and Identification (NS2400T and NS2400ST Systems)
This subsection includes these topics:
• “Terminology ” (page 114)
• “Rack and Offset Physical Location ” (page 115)
• “Blade Element Group-Module-Slot Numbering (NS2400T and NS2400ST Systems)” (page 115)

Terminology
These are terms used in locating and describing components:
DefinitionTerm
Computer system housing that includes a structure of external panels, front and
rear doors.
Cabinet
Structure integrated into the cabinet into which rack-mountable DC-powered
components are assembled.
Rack
The physical location of components installed in a modular cabinet, measured
in U values numbered 1 to 36 or 1 to 42, with 1U at the bottom of the cabinet.
A U is 1.75 inches (44 millimeters).
Rack Offset
A subset of a system that contains one or more modules. A group does not
necessarily correspond to a single physical object, such as an enclosure.
Group
A subset of a group that is usually contained in an enclosure. A module contains
one or more slots (or bays). A module can consist of components sharing a
Module
common interconnect, such as a backplane, or it can be a logical grouping of
components performing a particular function.
A subset of a module that is the logical or physical location of a component
within that module.
Slot (or Bay or Position)
A connector to which a cable can be attached and which transmits and receives
data.
Port
A notation method used by hardware and software in NonStop systems for
organizing and identifying the location of certain hardware components.
• Group-Module-Slot (GMS)
• Group-Module-Slot-Bay (GMSB)
• Group-Module-Slot-Port (GMSP)
In a NonStop NS2400 series system, OSM uses this term to hierarchically
differentiate between each blade element.
Blade complex
A DC-powered HP Integrity rx2800 i4 server that contains the processor element,
power supplies, fan assemblies, and firmware. A NonStop NS2400 series system
includes up to four blade elements.
