D-Link priemyselný Layer 2+ gigabitový spravovaný switch s 24 SFP portami a 4 portami 10G SFP+

The D-Link DIS-700G-28XS is a Layer 2+ managed switch with 28 ports designed for core network deployments that require reliable, rack-mountable hardware. It offers 24 SFP ports and 4 x 10G SFP+ slots (backwards compatible with 1G SFP), a MAC address table with 8,000 entries, USB 2.0 and RJ-45 console ports, and support for common IEEE networking standards in a 1U, 4.5 kg black chassis.

Advantages

The switch provides granular user management, diagnostics and security controls to shape managed network behavior. Its all-fiber-capable port layout with 10G SFP+ support enables flexible connectivity across a range of devices and topologies. The unit is officially certified for vibration, shock, free-fall and electromagnetic compatibility for deployment in demanding environments, and a fanless, rugged housing reduces maintenance and improves reliability. Rapid ring failover recovery under 20 ms supports high availability, and the product includes a 5-year D-Link warranty.

How to use

Install the DIS-700G-28XS in a standard 19-inch rack using the supplied mounting brackets and secure appropriate fiber transceivers in the SFP/SFP+ slots for desired uplink and access connections. Configure management parameters via the web or console interface: set VLANs, link aggregation, QoS, security policies and STP/Ring protection according to network design. Use the built-in diagnostics and monitoring tools to verify link status and performance, and store configuration backups via the USB port or centralized management system.

Recommendations

For high-availability deployments, enable ring or rapid spanning tree protocols and test failover behavior; ensure appropriate transceiver types are used for 10G and 1G links and verify environmental conditions meet the specified -10°C to +65°C range.
