The 24-Port 10/100Mbps Layer 2 Switch with 4 Gigabit Ports and 2 Shared Mini-GBIC Slots, model TL2-E284, provides a reliable foundation for a highly scalable managed network. The TL2-E284 features a 12.8Gbps switch fabric, 802.1X authentication, SNMP v3, and Multiple Spanning Tree (MSTP) support.

Built-in Gigabit Ethernet ports and Mini-GBIC slots provide high speed uplinks to backbone switching or servers. Configure the switch using your choice of Telnet, HyperTerminal, SNMP, or a Browser. View statistics captured for 17 unique switching parameters. Additional management features such as Port Trunking, IGMP snooping, Static and Dynamic VLAN, Load Balancing, RMON, QoS, and RSTP allow administrators to effectively manage departmental work groups.
