NonStop NS14000 Planning Guide (H06.10+)

Because the modular hardware provides considerable flexibility in how the hardware is distributed
among multiple cabinets, a single cabinet could contain four NonStop Blade Elements, with each
NonStop Blade Element a member of a different NonStop Blade Complex.
To reduce ambiguity in identifying proper cable connections to the NonStop Blade Complex,
the identification convention uses combinations of a letter to refer to each connection. A number
such as 0, 1, 2, and 3 identifies NonStop Blade Complexes, and a letter such as A, B, or C identifies
the NonStop Blade Element. Therefore, a single NonStop Blade Element is identified with an
alphanumeric ID, such as A1, A2, A3, and so forth. These IDs refer to the appropriate NonStop
Blade Element for proper connection of the fiber-optic cables.
The optic cables provide communications between each NonStop Blade Element and the LSU
as well as between the LSU and the VIO enclosures on the X fabric and Y fabric. No requirement
exists to connect cables from a particular Blade optics adapter on a NonStop Blade Element to a
physically corresponding adapter on an LSU. However, to help reduce the complexity of cable
connections, HP recommends that you use a physically sequential order of slots for fiber-optic
cable connections on the LSU and do not randomly mix the LSU slots.
Cable connections to the LSU have no bearing on NonStop Blade Complex number, but HP also
recommends you connect NonStop Blade Elements A to the NonStop Blade Element A connection
on the LSU. Optic cable connections to the VIO enclosure determine the identification numbers
of each NonStop Blade Complex. For more information, see “ServerNet Fabric I/O” (page 40).
This simplified example shows connections from a NonStop Blade Element to the LSU and to
the VIO enclosure:
