NonStop NS1200 Planning Guide
DefinitionTerm
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)
In an Integrity NonStop NS1200 system, OSM uses this
term to hierarchically differentiate between each blade
element.
Blade complex
An HP Integrity rx2660 server that contains the PE, power
supplies, fan assemblies, and firmware. An Integrity
NonStop NS1200 system includes up to eight blade
elements.

On Integrity NonStop NS1200 systems, locations of the modular components are identified by:
• Physical location:
— Rack number
— Rack offset
• Logical location: group, module, and slot (GMS) notation as defined by their position on
the ServerNet rather than the physical location
OSM uses GMS notation in many places, including the Tree view and Attributes window, and
it uses rack and offset information to create displays of the server and its components. For
example, in the Tree view, OSM displays the location of a power supply in a VIO enclosure in
group 100, module 2, slot 15 in this form:
Power Supply (100.2.15)
Rack and Offset Physical Location
Rack name and rack offset identify the physical location of components in an Integrity NonStop
NS1200 system. The rack name is located on an external label affixed to the rack, which includes
the system name plus a 2-digit rack number.
Rack offset is labeled on the rails in each side of the rack. These rails are measured vertically in
units called U, with one U measuring 1.75 inches (44 millimeters). The rack is 36U with 1U located
at the bottom and 36U at the top or 42U with 1U located at the bottom and 42U at the top. The
rack offset is the lowest number on the rack that the component occupies.
