Lantronix SM24TAT4XB Managed Gigabit Ethernet PoE+ Switches are high-performance switches with (24) 10/100/1000 copper ports and (4) dual-speed 1G/10G SFP+ slots. These switches support SSH/SSL security, jumbo frames up to 10240bytes, CSMA/CD protocols, Link Layer Discovery Protocol (LLDP), and a 128Gbps backpane. The SM24TAT4XB switches feature 100VAC to 240VAC internal power input, 44W (maximum without PoE), and 450W (full load with PoE) power consumption. The Device Management System (DMS) features graphical monitoring (Topology view, floor view, and map view), traffic monitoring, and troubleshooting (Network diagnostic, protection mechanism, and link management). The SM24TAT4XB switches comply with IEEE 802.3at PoE+, IEEE 802.3af PoE, and IEEE 802.1AB LLDP-MED configuration.
