The system was powder coated blue to match the customer's corporate color scheme.

Aerostat Camera GPU Processing Platform - 5 Week to Design and Manufacture Ultra rugged aerostat camera GPU processing computer The Department of Defense has deployed persistent surveillance systems on aerostats in Afghanistan. These systems scan a city-wide area constantly, day and night. When the system detects a threat in its field of view, a high resolution camera system including FLIR is employed to characterize the target.

The system developer required a custom rugged 5U system providing a high power System Host Board and four GPU processor boards in a PCI Express backplane to process the bandwidth coming down from the aerostat. In addition, 48TB of very high speed RAID storage is attached to the system to provide up to four weeks of image retention.

Because the systems are deployed on the battlefield in Afghanistan, Chassis Plans designed the system to be in full compliance with MIL-STD-810G including blowing sand and dust rejection and shock and vibration. The EMI gasketed front door contains a high efficiency air filter in combination with a honeycomb EMI filter. The three high reliability aluminum frame fans are controlled by Chassis Plans's SysCool® fan control board to maximize filter life while minimizing fan noise.

Chassis Plans engineered, fabricated, integrated and tested these systems in a very short 5 weeks allowing the contractor to meet their obligations with the Department of Defense.

Rugged Portable Computer w/ 17" LCD Ultra rugged portable computer system A defense contractor required a portable computer system which was very robust yet light in weight.

Custom 5U for Film Industry 5U Enclosure for Film EditingThe customer manufactured a film editing head. The target market was film dailys where the day's filming was proofed. A highly custom retro look was required as well as a proprietary rear panel for the many required connectors and cables. The resulting design is very attractive, provides a small color LCD display, is well cooled and provides ample fixed and removable data storage. Many custom non-PC boards are mounted inside the enclosure.

3U Enclosure with custom look and feel Custom Look 3U EnclosureThe primary requirement was for a non-Taiwanese appearance. While the Taiwanese manufacture many fine chassis, it becomes hard to differentiate your product because they all look the same. This customer wanted a highly unique "Assembled in the USA" appearance. Chassis Plans was able to modify a standard product line to provide this customer with a chassis look not found elsewhere.

Highly Custom 4U for Telco Industry Specialized Custom Telco NEBS EnclosureThis was a tough custom design. The initial requirement was to fit a chassis to a 21" telco rack, but have the design be able to also fit a 19" rack. The motherboard was a massive EATX dual Xeon server class board. Because this was a NEBS certified central office application, the system, including the massive processors, had to be ruggedly constructed to satisfy the seismic requirements of NEBS. Five external NIC connectors had to be available at the front panel.

The resulting design met all the customer requirements. It is NEBS compliant in all regards, fits both 19 and 21 inch racks, and is rugged enough to pass all seismic and transportation spectra when fully populated. Many application specific features were built into the chassis.

Reverse engineer the look but fix the problems Trimap Replacement ChassisThe customer was purchasing a chassis from a domestic supplier. The design was poor, the doors did not open completely, and the quality was poor. The customer was also having delivery problems. However, because of customer commitments, they could not switch to a different chassis.

CustomChassis Plans provided a chassis that looked the same but worked. The quality of the metal work was significantly better, the doors opened all the way, and the chassis had a much better look and finish. Not rocket science, but this simple chassis allowed the customer to keep several major customers.

Dual system nuclear plant simulator Nuclear Plant Simulation ChassisThis custom 4U enclosure was created to house two separate computers with independent single board computers and custom backplanes. Chassis Plans worked closely with the customer's engineering staff and other partners to create an enclosure to withstand high RF frequencies. The resulting design meets CE for susceptibility in high RF environments. The independent backplane chassis can be swapped in case of failure for a very low MTTR. This is another design which is highly customer specific that can not be satisfied by any off the shelf solution. Custom
