With the ability to operate at extreme -40 to 75°C (-40 to 167°F) temperatures, hardened managed switches offer advanced Ethernet management features, plus the redundancy and security elements required for essential applications. For backbone and central network layers, Layer 3 hardened managed switches provide routing between sub-networks with support for static routes, RIP V1/2, and VRRP. Redundant input power (both AC and DC) options help ensure maximized uptime, while Power over Ethernet (PoE) enabled switches deliver steady power to remote devices directly through the data cable.
