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

Daisy-chaining of D2700 SAS disk enclosures is not supported.
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 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” (page 70). 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:
