Subsystem Integrated Chassis Rugged Electronics Products

MSS expertise in data handling, ruggedization, and development to customer specification has allowed us to develop various rugged subsystem integration and rugged chassis electronic products.

Our solutions include integrating storage components with single board computers, adaptors, power supplies, cooling and heating systems, converters, backplanes, mil-spec connectors, and custom software in many different custom and standard form factors.

Attributes: Chassis Electronics

  • 6 slot liquid cooled 3U VPX chassis
    • SBC, P/S, 4x 128GB SSD
  • MSS designed VPX backplane
  • MSS designed & integrated Linux S/W
  • Qualified by MSS to full MIL-810 requirements (-40C to +85C)
    • 2x VPU, 2x SBC, P/S, E-Net Switch, I/O card
  • 8 slot conduction cooled 3U VPX chassis
  • 6 SSD removable drive bay
  • Minimal Cables / Edge Card

Multiple configurations, interfaces, and integrations

  • SAS, SATA, Fibre Channel and SCSI. MSS can develop VPX, VME, cPCI and custom form-factored products.
  • Software integration experience with Linux and Windows.
  • Commercial standard interfaces, as well as military connections like 38999.


  • An LRU storage and recording system for a military application that contains 1x VPX SBC, 1x Power Supply, custom VPX backplane, 1000 Base Optical Ethernet Transceiver PCBA, as well as 4x 128GB SSD units for storing mission data in an operational environment of -40CF to +71C. The MIL-STD-461F compliant 28VDC designed chassis is Liquid (Glycol/Water) cooled. MSS developed the entire software package to customer specification using Linux as the O/S. Each SSD unit is easily removable using levered wedge locks that also incorporate a 100,000 cycle blind mate connector. The only external interconnects from the military LRU are for Ethernet and Power. MTBF numbers exceeded stringent program requirements. The entire liquid conduction cooled chassis is built at our Longmont facility.

  • A network-attached Flyable Data Loader (FDL). This design and development were by MSS, including all the Windows-based software and qualification to full DO-160. The design incorporates a Blu-Ray drive, SBC, Power Supply and ECS (Environmental Control System). The purpose of the unit is to allow automatic data offload from either a USB or Blu-Ray disk in the aircraft cabin to a server located in the Electronics Bay.

  • The unit houses two removable sealed 128GB SATA SSD units that mount via levered wedge locks. This allows for easy removal of just the storage modules, without removing the entire 6U VME card. This design has been qualified to the harshest of military environments.
