New 1U Chassis Meets Mission Critical Demands for High Reliability/High Power Applications


COLUMBUS, OH, November 18, 2002-Tracewell Systems, Inc., a world-class electronic packaging manufacturer, has introduced the S33-1U system for mission critical CompactPCI and VME64x applications that must utilize high-density cards without sacrificing reliability. The new S33-1U provides the systems designer a field-proven standard solution for what has currently only been offered in the marketplace as a custom-engineered chassis.

The high efficiency cooling of the S33-1U makes it well suited for tele/datacom and military/government applications as well as other programs where compact 1U size is critical.

Specially Designed For High-Performance Processor Cards. Tracewell designed the S33-1U to address a need for high reliability and density. No other commercially available 1U chassis provides the cooling performance needed to handle boards dissipating up to 70 watts per slot. The S33-1U offers more advanced cooling and power performance than other 1U custom solutions, along with sophisticated local and remote monitoring capabilities to support ongoing system performance and diagnostics. Demanding product specifications were based on the need to support the latest generation of high-performance processors used in mission-critical processing system applications for military, government and telecom programs.

To accommodate the greater heat generated by these high-density boards, the S33-1U employs a push/pull cooling scheme that provides high-capacity cooling of up to 70 watts for each of the two slots, with no greater than 20 degree temperature rise at 55 degrees C. No other standard 1U chassis in the industry is able to provide cooling at the 70 watts/slot level. This specialized push/pull scheme, originally designed for telecom and military-level applications, works to overcome the pressure loss caused high-density boards ensuring consistent airflow.

Airflow is distributed evenly within the chassis via seven fans providing 15 CFM each, more than most 1U solutions on the market, arranged specifically to cool dense high-end multi-processor cards. The unit incorporates a 250W power supply.

Tracewell's unique machined design provides a robust and rugged system for even harsh applications, the S33-1U provides greater stiffness than similar 1U chassis built from conventional formed parts. The chassis houses a two-slot CPCI backplane that supports hot swap and System Management Bus capability. A two-slot VME64x version is also available. Cards are rear-mounted in the chassis, which measures 13.7"D (350mm), 10.0"W (483mm), 1.74"H (44mm).

High Reliability in the Field. To help maintain critical power and cooling operating conditions within the chassis, Tracewell has enhanced its remote and local monitoring capabilities on the S33-1U. The system relies on a "PIC" processor-based monitoring system, which allows for greater flexibility and software control, particularly useful in remote monitoring applications. Local monitoring via front-panel LED readouts is provided, with remote monitoring supported via RS-232 ports for temperature and voltage levels. Ethernet capability can also be provided.

As with all Tracewell products, the S33-1U can be adapted per Tracewell's ABC Modification Program to support customer specific requirements, including board-level integration.

Price and Availability. Tracewell's S33-1U starts at $2,575 and typically ships eight weeks ARO.
