Chassis management for VPX systems
Systems built to VITA standards, such as VME, have not traditionally needed the high reliability of many of the telco systems, and have relied upon front panel LEDs to indicate fan failure, voltage monitoring, and thermal issues with the boards and chassis. While VME has long been the preferred architecture of the military and aerospace industry, as higher speeds and increased reliability became more critical to system operation, it was apparent that these older architectures just wouldn’t cut it. VPX, or VITA 46.0, was VITA’s answer to implement modern high-speed interconnects, real-time monitoring, and remote mitigation of certain system parameters in harsh environmental applications.
