Modular Cabinet PDU Keepout Panel
Modular Cabinet PDU Keepout Panel
PDU keepout applies only when the PDU junction boxes reside at the bottom of the
modular cabinet. PDUs overlap the outside of the rack by 2 U (3.5 inches). A PDU
keepout panel is installed in affected space when:
•
1U keepout applies when a UPS occupies the bottom position of the modular
cabinet.
•
2U keepout applies when a NonStop Blade Element occupies the bottom position
of the modular cabinet.
NonStop Blade Element
The NonStop Blade Element enclosure, which is 5U high and weighs 112 pounds (46
kilograms), has these physical attributes:
•
Rackmountable
•
Redundant AC power feeds
•
Front-to-rear cooling
•
Cable connections at rear (power, reintegration, LSU) with cable management
equipment on the rear of the cabinet
Each NonStop Blade Element includes these field replaceable units (FRUs):
•
Processor board with up to four Intanium microprocessors, interface ASIC, clock
generation (accessed through front of enclosure)
•
Memory board that can hold up to 32 DIMMs, each one 4 GB, for a total memory
capacity of 128 GB (accessed through front of enclosure)
•
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 for parallel to serial conversion and maintenance logic (requires
removal of enclosure from rack)
•
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, with eight NonStop Blade Elements providing a full 16-
processor duplex system. For a fault-tolerant triplex system, three NonStop Blade
