Enterprise-Class Enclosure measures 11U high.

Press Release Summary:

Equipped with 2,000 W power supply, enclosure uses 3 fans and 3 blowers to produce airflow sufficient enough to cool over 90 W of available power per slot. Unit supports combinations of 21-slot wide segmented, monolithic, or custom backplane designs with CompactPCI®, CompactPCI Express, VME, or VXI busses. Optional Internet-based system monitor and alarm board, coupled with Java-based monitoring software, allows operator to remotely monitor system functions.

One Stop Systems Introduces 11U High Enterprise-Class Enclosure

o 21-slot, PICMG 2.16 packet switched or custom backplane
o 2,000 watt high capacity power supply
o Superior cooling with four fans and four blowers with hot-swap
o Optional Internet-based system monitor

December 2004, Escondido, CA - - One Stop Systems announces the introduction of its 11U high enterprise-class enclosure for CompactPCI® applications. The 21-slot CompactPCI® backplane provides 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 CompactPCI®, 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.

"The 21-slot, 19" wide, enterprise-class enclosure expands One Stop Systems' line of 6U card technology enclosures," said Steve Cooper, president and CEO. "Its 2,000 watt power supply provides over 90 watts of power per slot while our cooling system provides a virtual whirlwind of cooling to each slot. The system monitor contains all the intelligence and application software to monitor critical system parameters. The ability to configure this enclosure for the CompactPCI® bus as well as the new CompactPCI Express bus underlines the commitment of One Stop Systems to be a true one stop source for industrial-grade computer systems."

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.

The 21-slot wide enclosure starts at $8,895 with a bridged CompactPCI® backplane and is available immediately.


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.


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 CompactPCI® 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.
