One Stop Systems' 11U high enclosure includes a 21-slot CompactPCI backplane, providing significant
capacity for high-density applications. A 2,000 watt, high-efficiency
power supply provides plenty of power to the most power-hungry
application cards. The technologically advanced cooling system
consisting of three fans and three blowers offers the airflow
required to cool the over 90 watts of available power per slot.
The enclosure supports many combinations of segmented, monolithic
or custom backplane designs with CompactPCIâ, CompactPCI
Express, VME or VXI busses. One Stop Systems’ system monitor
and alarm board coupled with the Java based monitoring software
allows the operator to remotely monitor vital system functions.
The enclosure is designed to meet all emissions and safety requirements
including UL, cUL, FCC and CE.
This enclosure targets the often-neglected
market segments requiring large slot counts, high-speed backplanes
and high board density but with less need for high availability
and NEBS certifications. This enclosure is especially well suited
to the communications test equipment, industrial control, military,
scientific and large enterprise server markets.
Backplanes
The monolithic backplane is 21-slot CompactPCI PICMG 2.16 packet
switched backplane specification-compliant. The backplane has
one system slot, one or two switch slots and eighteen or nineteen
slots for peripheral boards. Each slot provides rear I/O access
on P3-P5 connectors. One version of the backplane also includes
H.110 telephony bus. Pallet-style bridge boards span the rear
P1-P2 connectors to provide a continuous CompactPCI bus. The
bridge board does not interrupt the operation of any slot or
interfere with rear I/O boards. The backplane also provides sufficient
power input connectors for the 2000-watt power supply located
under the card cage area of the enclosure. Other backplanes supported
include 21-slot VME-compliant backplanes as well as backplanes
based on emerging standards including CompactPCI Express.
Power supplies
The 3U section under the card cage
area of the enclosure houses the 2,000-watt power plant. This power
supply provides ample 3.3V, 5V, +12V, and –12V, to each of the card slots including
200A of 5V and 180A of 3.3V power. The power supply is equipped
with a high current power connector and is hard mounted in the
enclosure. A -48VDC version includes a single –48VDC input
power supply.
Cooling
The card cage area of the enclosure offers
three (3) fans in individually hot swappable canisters mounted
below the card cage in the oversize filtered air intake area and
three (3) individually hot swappable blower canisters mounted above
the card cage. Each of the 150 CFM fans pull ambient air into the
card cage through the front of the enclosure. The 40 CFM blowers
then pull the air up across the boards and exhaust it out the rear
of the enclosure. If one of the devices stops or fails to operate
properly, it can be easily replaced without interrupting the system’s
operation and while maintaining a cool system temperature.
The power
supply section of the enclosure offers an 80 CFM fan at the front
of the enclosure to provide directed airflow over the power supply
while a 40 CFM blower exhausts the air out the rear of the enclosure.
The use of these fans in the revolutionary configuration along
with the oversize filtered air intake and mixing plenum provide
the virtual whirlwind required to cool this powerhouse system.
System monitor
The OSS System Monitor is a 6U CompactPCIe board
with transition module. It provides monitoring of temperature,
fan rotation, DC voltage levels, and CPU activity. It also controls
the blower speed, which reduces noise when the blowers are not
required to run at full capacity. The transition module provides
the interface to all of the I/O including fans, blowers, temperature
sensors, relays, serial port and Ethernet port. The Internet-based
firmware allows remote monitoring of the system’s vital
parameters from anywhere in the world.
