Power-over-Ethernet (PoE) technology has become popular and there are many devices that are PoE ready: PoE cameras, VoIP phones, wireless radios, and access controllers. These technologies have been widely adopted in industrial markets that include automation manufacturing, security surveillance, power/utility, water wastewater treatment plants, oil/gas/mining, and transportation industries. The LNP-2804GN-SFP-T works well in wide temperature environments that require rugged Power Source Equipment (PSE) networking equipment with high-density Ethernet port connectivity, long distance data transmission, and reliability.
The LNP-2804GN-SFP-T is a rackmount industrial Gigabit PoE+ managed Ethernet switch that offers twenty-four full Gigabit Ethernet ports with a PSE maximum of 30 W per port and four combo ports featuring four SFP fiber slots for long distance connectivity or four 10/100/1000 twisted pair ports. This product series has an IP30 rated metal casing design that can be mounted in a 19 in. rack. The device provides a dual redundant power input range of 46 to 57 Vdc with an overload current and reverse polarity prevention, as well as high EFT surge and ESD protection. Additionally, there is a built-in relay warning function to alert maintainers when power failures occur on one of the two power sources. Each unit is built to withstand industrial networking hazards like shock, drop, vibration, electromagnetic interference (EMI), and temperature extremes (-40°C ~ 75°C). The unit dimensions are 438 mm (W) x 259.2mm (D) x 43.6mm (H) and a unit weight of 8.37 pounds.
