Internal Cable Part Numbers
Although a considerable cable length can exist between the modular enclosures in the
system, HP recommends placing all cabinets adjacent to each other and bolting them
together, with cable length between each of the enclosures as short as possible.

For part numbers, see Internal Cables on page A-1.
NonStop Blade Elements to LSUs
Fiber-optic cables provide communications between each NonStop Blade Element and
the LSU as well as between the LSU and the X-fabric and Y-fabric p-switch PICs. The
ServerNet X fabric and Y fabric provide the system I/O from the p-switch PICs to the
IOAM, with Fibre Channel and high-speed Ethernet links providing connections to
storage and communications LANs, WANs, and so forth.
Cable connections between the NonStop Blade Elements and the LSU optics adapters
affect proper processor synchronization and rendezvous. For each logical processor
element (PE), the port for a particular PE, such as PE1 (NonStop Blade Element port
J0) on DMR NonStop Blade Elements A and B or TMR NonStop Blade Elements A, B,
and C, must connect to their respective ports on the LSU optics adapters as shown in
the example connection diagrams in LSUs to Processor Switches and Processor IDs.
Although you can randomly select LSU optics adapters for fiber-optic cable
connections, HP recommends connecting these cable to the LSUs in sequential order
as shown in the connection diagrams.
NonStop Blade Element to NonStop Blade Element
Reintegration cables interconnect each of the NonStop Blade Elements within
individual duplex or triplex NonStop Blade Complexes using connectors S, T, Q, and R
as shown in the illustrations on the next four pages.
LSUs to Processor Switches and Processor IDs
Each NonStop Blade Element contains four processor elements, and each element is a
part of a numbered NonStop Blade Complex, such as 0, 1, 2, or 3. The maintenance
entity (ME) firmware running in the p-switches assigns a number to each processor
element based on its connection from the LSUs to ServerNet via the p-switch ports in
slots 10-13. Therefore, fiber optic cable connections from the LSUs to the p-switch
PICs determine the number of each NonStop Blade Complex.
This table lists the default p-switch PIC slot and port coupling to the processor number:
