SWITCHES

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.
