GTL-2891 하드웨어 버전: 1 28-Port Stackable L3 Managed Gigabit Switch, 2 x 10-Gigabit SFP+, 1 x 10-Gigabit Module Slot 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 networkattached files servers over fiber ports. They can also be deployed as a backbone upgrade, or to provide Gigabit–to-thedesktop 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.
