28-Port L2+ Fully Managed PoE+ Switch with 24 Gigabit Ethernet Ports and 4 SFP+ Uplinks

This 24 + 4 Layer 3 Lite Gigabit Switch is a high-performance SNMP-managed device that provides users with 24 10/100/1000 Mbps Ethernet and 4 additional 10G SFP+ ports. The Web/SNMP management provides remote control capability for flexible network management and monitoring options. Whether managed through an "in-band" SNMP management station or an Internet Web browser, this Intellinet Network Solutions Gigabit switch facilitates network administration and problem diagnosis. It can also be trunked, providing a linkup to 40G to another switch.
