The CR-6900-RJ45-LC GMC MIL SERIES is a fully rugged managed gigabit Ethernet switch and router product line specially designed to operate reliably in harsh climatically and noisy electrical demanding environments (e.g. high altitude, extreme shock, and vibration, wide temperatures, humidity, dust and water exposure, noisy EMI, dirty power) of military applications. The platform is an advanced and highly engineered switch/router that addresses complexity, enables modularity, and provides growth, while delivering optimal performance for Space, Weight, Power and Cost (SWaP-C) constrained military applications onboard military vehicles. The unit complies with the military environmental, EMC, and power input requirements.

This rugged rack switch and router are based on a separate router board that is equipped with the OnTime Networks router and firewall package providing routing speeds up to 800Mbps and supports a wide range of routers including multicast routing. The rack-mount switch/router contains a PTP 1588 Grand Master Clock (GMC) with an accuracy better than 30 nanoseconds and with PTP version translation (v1/v2) support with a built-in GNSS receiver. The unit can also provide other time synchronization outputs. NMEA/PPS and IRIG-B 002 (DC) can be taken as time-based input as an alternative to GNSS.

  • 10G & MANAGEMENT BOARD – 1G-T only is Standard, 10G-Cu/10G-X+1G-T also available
  • OCXO – The platform can be equipped with a high-end OCXO for extreme clock hold-over capability in case the time base source is lost. This means minimum clock drift even in an environment with large temperature variations.
  • BATTERY – A Li battery can be used to keep track of the time of day when the unit is not powered. The lifetime of the battery is more than 10 years.
  • PoE – PoE support with a power budget of up to 150 watts can be provided on up to 12 x 10/100/1000Base-T ports.
  • Router Engine – many options available
