NonStop Blade Element
so forth. These IDs reference 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 p-switch PICs 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 that you not randomly mix the LSU slots.
Cable connections to the LSU has 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 p-switch PICs
determine the identification numbers of each NonStop Blade Complex. For more
information, see ServerNet Fabric I/O on page 4-9.
This simplified example shows connections from a NonStop Blade Element to the LSU
and to the p-switch:
