PROCESSING CORE
AC Power
The operating AC voltage is 100-240V +/-10%, 50-60Hz.
The processing core has 2 slots for AC fed PSU modules. The core will be fully functional
on one PSU, however both should be fitted and fed where possible from separate sources to
provide redundancy against both PSU failure and external power loss.
The inrush current is actively limited to 13A peak at 230V (6.5A at 115V) per power supply
module, reducing the chances of a nuisance trip or blown fuse from brown-out conditions or
black-out recovery.
The PSU modules are high efficiency and employ active PFC (Power Factor Correction).
The power factor is > 0.9 under all operating conditions.
DC Power
The core PSU modules share the load of the whole core, their DC outputs being combined and
tracked across the core backplane to each card slot. All core module type's, including the PSU's
are hot-pluggable and self-initialising.
Core PSUs output 56V DC. Each processing module within the core performs local isolated DC-
DC conversion, operating over a wide input range of 36-75V to provide a high level of immunity
against surges, dips and transients in supply.
Heat Output & Efficiency
The heat output from the core is nominally 0.93 x total RMS VA.
The maximum possible heat output in a fully populated core is 320W.
Cooling
The core is cooled by fan assisted convection. Fan speed is monitored and warnings generated
if any fan slows or stops.
6 x 120mm low power, low speed and low noise fans are mounted inside the top of the core.
Air is drawn in from the cable-tray and up through the bottom of the cardframe.
Air is vented out of the top of the rear of the core.
No clearance is required above or below the core for cooling or airflow.
At least 50mm (2') clearance must be maintained at the top of the rear of the cores to allow
the fans / vents to dissipate air. The cable tray should not be blocked and should be allowed
sufficient clearance to maintain cooling.
The core may be mounted in an open bay providing the ambient air temperature is within limits
(see below). The core may also be housed in an air conditioned bay providing the air pressure is
negative. Consult factory for positive air pressure systems.
Acoustic Noise A fully populated core produces <40dB acoustic noise (A-weighted, 1m from front).
