1 nnn indicates the length of the cable in meters. For example, M8900125 is 125 meters long; M8900-15 is 15 meters
long.
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.

NonStop Blade Elements to LSU
Fiber-optic cables provide communications between each NonStop Blade Element and the LSU
as well as between the LSU and the VIO enclosure. The ServerNet X fabric and Y fabric provide
the system I/O from the LSU to the VIO enclosure, 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 “LSU to VIO
Enclosure and Processor IDs” (page 80). 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.
LSU to VIO Enclosure 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 VIO enclosure assigns a number to each processor element based on its connection
from the LSU to the ServerNet-to-processor ports in slots 14.1 through 14.4 (processors 0 through
3) and slots 2.1 through 2.4 (processors 4 through 7). Therefore, fiber-optic cable connections
from the LSU to the ServerNet-to-processor ports on the VIO enclosure determine the processor
number of each NonStop Blade Complex.
This table lists the default VIO enclosure slot and port coupling to the processor number:
