Each industrial layer 2 rackmount switch is equipped with an IP30 rated metal enclosure, designed to withstand a high degree of vibration and shock, while operating within a wide temperature range of -40° - 70° C (-40° - 158° F) for industrial environments. Our industrial layer 2 rackmount switch models feature copper gigabit ports for high-speed device connections, as well as SFP slots that support 100/1000Base-FX SFP modules for long distance fiber networking applications. These industrial layer 2 rackmount switches feature a fanless design that eliminates operating noise and lowers energy consumption.These Industrial Gigabit L2 Managed PoE+ Rackmount Switch Series provides an intuitive web-based management interface. Each TRENDnet industrial layer 2 rackmount switch supports advanced traffic management controls, troubleshooting, and SNMP monitoring. Advanced managed switch features include LACP to group ports together and increase bandwidth between switches, VLANs for segmenting and isolating virtual LAN groups, QoS to prioritize traffic, port bandwidth controls, SNMP monitoring, and more, making each TRENDnet industrial layer 2 rackmount switch a powerful solution for SMB networks.
