Housed in a 4U 19" rackmount platform, the 7-slot 3U high performance VPX backplane provides the interconnect between the system processor and the DSP, FPGA and switch cards required this system implementation. The high performance Intel 2.8GHz Xeon® processor runs on the VxWorks real-time operating system, with 16GB of memory and 64GB NAND flash. External interfaces are implemented with fibre optic links to ensure isolation is maintained from other equipment within the overall system. Multiple power supply modules ensure reliable redundancy. The design allows for versions tailored to rugged environments to withstand shock and vibration as well as extended temperature operation. Temperature, fan and chassis monitoring is included through an integrated chassis manager with faults shown via LEDs on the front panel as well as being reported through Ethernet and serial interfaces.
