GTL-2891 Datasheet, PDF (1/5 Pages) Level One – Stacking up to 8 switches in one stack

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 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.
