SWITCHES

The GTL-2891 are a family of high-performance Gigabit Ethernet Layer 3 switches featuring 28 ports| with 24 10/100/1000BASE-T ports. 2 10G SFP+ ports. and one 10G dual port expansion slot. The switches are ideal for high-performance server aggregations. such as enterprise data centers. where they can connect high-end or network-attached files servers over fiber ports. They can also be deployed as a backbone upgrade. or to provide Gigabit–to-the-desktop for power users. These switches are packed with features and are a cost-effective solution that bring continuous availability. enhanced security. and advanced QoS to the network edge. while maintaining simplicity of management.
