Elma’s New Chassis Manager Ensures Proper Board and Chassis Operation in Systems Aligned to SOSA

Versatile card easily integrates into wide range of defense embedded computing platforms
Technology Highlights
  • Chassis manager aligned to SOSA Technical Standard 1.0 with power management and cooling control
  • Compliant with VITA 46.11 Tier 3, with firewall and SOSA out-of-band command support
  • Designed for a wide range of harsh embedded applications
  • Web-based GUI for clear, convenient access to system data
FREMONT, Calif., April 2023 – Elma Electronic offers a VPX Chassis Manager that aligns with The Open Group Sensor Open Systems Architecture™ (SOSA) Technical Standard 1.0 and supports the Modular Open Systems Approach (MOSA) standardization initiative from the U.S. Department of Defense (DoD).
The new VITA 46.11 Tier 3 chassis manager comes as a standalone unit or can be mounted on a carrier card. 3U and 6U conduction-cooled plug-in versions and an air-cooled 3U version are also available. The card offers firewall support and SOSA out-of-band command support as well as 16 digital inputs and 16 configurable digital outputs that provide a high degree of system management function.
Ideal for use in a wide range of embedded computing applications through the military and defense industries, the new chassis manager helps ensure overall system health and proper operation. This includes maintaining a components and sensor inventory and receiving reports and notices from installed intelligent field replaceable units (FRU). The SOSA aligned chassis manager can also adjust the fan speed for over/under temperature conditions and report or shut down the system due to over or under voltage and current conditions.
Mark Littlefield, director, systems products for Elma Electronic Inc., commented, “With a chassis manager aligned to SOSA, we’re able to give system engineers a tool that monitors overall health and also identifies anomalies and takes corrective action in systems developed to meet today’s interoperability initiatives as put forth by the DoD.”
Additional features include power management and cooling control, event sensor logging, electronic keying and card hot-swap monitoring. A redundant IPMB ensure maximum system uptime. The chassis manager operates over an extended temperature range of -40°C to +85°C.
A web-based graphical user interface (GUI) monitors up to 12 fans, eight analog inputs and six external thermistors. All data is presented in a clear, concise graphical representation with complete sensor information available with the click of a mouse. Parameters that can be monitored include health, voltage, fan RPM, power and temperature as well as device ID, serial and port numbers and software versions.

Accelerating Embedded Software Development with the Intel® Simics® Simulator for Intel FPGAs

Sponsored by Intel

In a traditional FPGA design flow, the main portion of the software development cannot start until hardware is available. Intel provides the Intel Simics simulator for Intel Agilex 5 SoC FPGAs to give developers a vehicle to exercise their software in parallel with hardware development. Developers can run the same compiled binary software files providing the same results in the software’s execution. Software can be developed, debugged, and verified on the virtual platform up to a year in advance of the physical hardware becoming available.

Megawatt Chargers in Electric Commercial Vehicle Infrastructure
In order to move forward with the large-scale implementation of commercial electric vehicles, we need to consider efficiency, availability, reliability, and longevity for the mega-watt chargers required for these applications. In this episode of Chalk Talk, Dr. Martin Schulz from Littelfuse joins Amelia Dalton to discuss the infrastructure demands of electric commercial vehicles, the role that galvanic isolation plays here and why thyristors may be a great choice for the future of electric commercial vehicles.
