EN50155 Managed FE PoE Switches

EN50155 Managed FE PoE Switches



The ITP-802GSM-8PH24 series are managed industrial grade Ethernet PoE (Power over Ethernet) switches with 8x 10/100Base-TX PoE ports and/or 2 SFP Gigabit/Fast Ethernet ports that provide stable and reliable Ethernet transmission in challenging applications. The ITP-802GSM-8PH24 series is equipped with PoE feature enable power and data to be transferred via a single cable, hereby considerably reducing cabling expense. The ITP-802GSM-8PH24 series also provides a variety of functions to manage PoE operation including PoE device auto-checking, auto reset, PoE power weekly scheduling. Other L2 management functions supported include STP/RSTP/MSTP/ ITU-T G.8032 Ring and multiple u-Ring for redundant cabling, layer 2 Ethernet IGMP, VLAN, QoS ,Security, IPv6, bandwidth control, port mirroring, cable diagnostic and Green Ethernet. Housed in rugged DIN rail or wall mountable enclosures, these switches are designed for the harshest environments. The ITP-802GSM-8PH24 series switches use M12 connectors to ensure tight, robust connections and to guarantee reliable and anti environmental disturbances operation, such as vibration and shock. The ITP-802GSM-8PH24 series are compliant with EN 50155, covering power input voltage, surge, EFT, ESD, vibration, shock, thus making the switches suitable for industrial applications, such as vehicle, rolling stock, ship, vessel. The ITP-802GSM-8PH24 series are IP67 rated to protect against dust and water submersion. They are particularly used in environments with extreme temperature, high humidity, oil, dust and in outdoor environments requiring water-proof applications such as IP surveillance, city security.
