NonStop NS14000 Planning Guide (H06.10+)

• DIMMs
• Reintegration board for managing internal memory traffic (accessed from top of enclosure
when enclosure is pulled forward on its rails)
• Blade optics adapter plug-in cards (PICs) with two ports; two adapters minimum, eight
maximum (accessed from top of enclosure when enclosure is pulled forward on its rails)
• Redundant cooling fans (accessed from top of enclosure when enclosure is pulled forward
on its rails)
• Redundant 220-240 V ac power supplies and power cords (accessed from back of of enclosure)
• I/O interface board, NonStop Blade Element I/O interface board for parallel to serial
conversion and maintenance logic (requires removal of enclosure from modular cabinet)
• Front panel with indicator LEDs and power buttons
The NonStop Blade Element midplane for logic interconnection and power distribution, which
is part of the chassis assembly, is not a FRU.
Two NonStop Blade Elements provide up to four processor elements in a high-availability duplex
configuration, and four NonStop Blade Elements provide an 8-processor duplex system. For a
fault-tolerant triplex system, three NonStop Blade Elements provide four processors, and six
NonStop Blade Elements provide an 8-processor triplex system.
NOTE: Integrity NonStop NS14000 systems do not support duplex and triplex processors
within the same system.
This illustration shows the rear of the NonStop Blade Element, equipped with two power supplies
and eight Blade optics adapters:
The numbers below the optics connectors refer to the processor numbers within the NonStop
Blade Element enclosure. Currently, only connectors J0, J1, J2, and J3 are used. The remaining J
connectors are for future use by the NonStop Blade Element hardware.
CAUTION: To maintain proper cooling air flow, blank panels must be installed in all slots that
do not contain Blade optics adapters.
Labels for the fiber-optic cable connections can become complex in a large system. Fiber-optic
cables for the ServerNet fabric and also the optic cable connections use the same type of optics
connector.
