The CM-4004F0-GMC-MIL is a fully rugged managed gigabit Ethernet switch 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 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 fully managed, Layer 2/3 gigabit switch provides a powerful set of networking features, including support for IPv4 multicast traffic filtering according to static filters or IGMP snooping, Virtual Local Area Networks (VLANs), port control (speed/mode/statistics, flow control), Quality of Service (QoS) traffic prioritization, Link Aggregation (802.3ad), SNMP v1/v2/v3 management, secure authentication (802.1X, ACLs, Web/CLI), port mirroring and network redundancy based on RSTP/MSTP.
The CM-4004F0-MIL-GS082UBN0 contains a PTP 1588 Grand Master Clock (GMC) with PTP version translation (v1/v2) support with an external time source as a time base (e.g. GNSS or IRIG-B 002 (DC)). The unit also contains an NTP server.
