LevelOne KILBY 28-port stackovateľný L3 Managed Gigabit switch, 2 x 10GbE SFP+, 1 x 10GbE modulový slot

The GTL-2891 is a family of high-performance Gigabit Ethernet Layer 3 switches with 28 ports: 24 10/100/1000BASE-T ports, 2 10G SFP+ ports, and one 10G dual-port expansion slot. These switches are designed for server aggregation in enterprise data centers, backbone upgrades, and providing Gigabit-to-the-desktop connections for power users, supporting fiber and copper connectivity while delivering continuous availability and simple management.

Advantages

The GTL-2891 series offers a combination of high port density and 10G uplink options, making it suitable for connecting high-end servers and network-attached storage. Layer 3 capabilities and advanced QoS improve traffic management, while built-in security features increase edge protection. The devices balance performance and cost-effectiveness for enterprise deployments and are intended to simplify network operations with centralized management support.

Key specifications

• Ports: 24 x 10/100/1000BASE-T
• Uplink ports: 2 x 10G SFP+
• Expansion: 1 x 10G dual-port expansion slot
• Switching: Gigabit Ethernet, Layer 3 routing capabilities
• Typical use cases: server aggregation, data center access, backbone upgrade

How to use

Install the GTL-2891 in a standard rack and connect server or storage devices to the 1G copper ports and high-performance uplinks to the 10G SFP+ ports or the 10G expansion slot. Configure Layer 3 routing, VLANs, QoS, and security policies according to network design using the device management interface. Use the 10G interfaces for aggregation to core switches or for connecting high-bandwidth servers over fiber.

Recommendations

For optimal performance, connect high-throughput servers and NAS devices to the 10G SFP+ ports or the 10G expansion slot and reserve the 1G ports for desktops and less demanding equipment. Keep firmware updated and configure QoS and security features to match your traffic and access requirements.
