Power PoE devices in harsh environments. Reliable and rugged Unlike the Ethernet switches in your wiring closet or computer center the switches at the edges of your network have to withstand extreme temperatures and conditions. This is where the Industrial Unmanaged Gigabit Ethernet PoE+ Switch from Black Box comes in. This extreme industrial switch features eight autosensing 10-/100-/1000-Mbps PoE/PoE+ 802 af/at copper ports and two Gigabit copper ports. Use this rugged switch in harsh environments with temperature extremes of -40degree to +75degreeC such as loading docks remote monitoring stations and industrial facilities. PoE versatility Use the switch's eight PoE ports to power remote PoE/PoE+ PSD devices such as security cameras traffic signals wireless access points building access devices and automation equipment in areas where it may be difficult to run electrical wiring. The switch is built for extreme environments with uncontrolled temperatures of -40 to +167degree F (-40 to +75degree C). The rugged IP30 metal case is sealed to resist contaminants such as dust dirt and moisture and can be DIN-rail or wall mounted. A multitude of applications, Security and surveillance particularly to backhaul IP security camera data Military applications especially in ships and other vehicles, Factory automation for controlling machinery PLCs motor drives sensors counters inspection cameras and packaging equipment, Oil and gas fields or remote equipment monitoring and control, Building automation for controlling HVAC and lighting systems. Security/surveillance to backhaul IP camera data. Redundant power and alarm alerts For redundancy the switch has two 12-24 VDC power inputs with a P-fail relay. If one power source fails the switch automatically falls over to the second power source. The switch also has a P-Fail LED which in the event of a power failure will activate the alarm to notify administrators. The switch supports jumbo frames up to 9216 bytes. This product is covered by one or more of the following United States Patent Nos. 7457250 8902760 and/or 9019838.
