This custom 4U enclosure was created to house two separate computers with independent single board computers and custom backplanes. CP Technologies 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.
