The Curtiss-Wright/Parvus DuraNET 3300 is a ruggedized Cisco Ethernet switch built for operation in harsh military and industrial environments where standard commercial networking equipment cannot survive. The NET-3300-12H delivers Gigabit switching and Cisco IOS routing capabilities in a compact, fanless enclosure tolerant of shock, vibration, extreme temperature, humidity, and electromagnetic interference. Dual power inputs ensure redundancy and seamless failover across vehicle and aircraft power systems.
