The XPand6211 is a Commercial-Off-The-Shelf (COTS) Rugged 24-port Gigabit Ethernet switch and router with a compact design that maximizes processing and networking performance while minimizing SWaP. The XPand6211 provides a SWaP-optimized alternative to traditionally larger slot-based systems; it is an actual Small Form Factor (SFF) system based on two COTS XChange3013 3U VPX Gigabit Ethernet switches.The XChange3013 delivers full wire-speed across all of its ports and supports jumbo packets up to 12 kB. It supports IPv6, Energy Efficient Ethernet (EEE), and a comprehensive set of IETF RFCs and IEEE protocols.The XPedite5205 Cisco IOS® Router XMC can be installed on the XChange3013 to provide highly secure data, voice, and video communications to stationary and mobile network nodes. The XChange3013 optionally supports compliance with the VICTORY specification as an Infrastructure Switch and Router.The XPedite8103 provides general-purpose computing with best-in-class performance-per-watt. The Intel® Atom™ E3800 family of processors support extremely low operating temperatures, and its power-efficient 22 nm technology enables operation in the most demanding high-temperature environments.This fully ruggedized system is designed to meet the rigorous standards of MIL-STD-810 and DO-160, while integrating the latest power-saving and performance-enhancing technology. The heat from the internal conduction-cooled modules is conducted to sidewall heat exchangers,where it is dissipated to the ambient environment by convection cooling or to an attached cold plate by conduction cooling. The system includes an integrated 28 VDC power supply and MIL-STD-461 EMI filtering.
