LevelOne KILBY 28-Port Stackable L3 Lite Managed Gigabit Switch, 2 x 10GbE SFP+, 1 x 10GbE Module Slot
The GTL-2881 series includes high-performance Gigabit Ethernet Layer3 Lite switches featuring 28 ports; 24 10/100/1000BASE-T ports, two 10G SFP+ ports, and one 10G expansion slot for a dual-port module. The switch is ideal for high-performance server aggregations, such as enterprise data centers, where it can connect high-end or network-attached file servers through fiber ports. It can also deployed as a backbone upgrade, or to provide Gigabit-to-the-desktop for power users. This switch is packed with features and is a cost-effective solution that brings continuous availability, enhanced security, and advanced QoS to the network edge, while maintaining simplicity of management.
