D-Link DGS-1250-28X

1250-28X 28-Port 10-Gigabit Smart Managed Switch

The D-Link DGS-1250-28X is a powerful yet cost-effective 28-port Smart Managed switch, tailored for SMBs and enterprise edge deployments. Combining 24 Gigabit Ethernet ports with four 10 Gbps SFP+ uplinks and rich Layer 2/Lite-3 capabilities,it's ideal for high-performance networking with reliable surge protection and simplified management.

Features

Built for performance and scalability, the DGS-1250-28X provides broad connectivity with its mixed port configuration×perfect for linking servers, NAS devices, and uplinking to core switches. It supports essential L2 features like VLAN, STP/RSTP/MSTP, link aggregation (LACP), and IGMP snooping, while offering Lite L3 static routing for inter-VLAN traffic. The device is managed via an intuitive web interface (11 languages), CLI, or console port, making setup and monitoring simple.

Advanced Options

Advantageous for surveillance and VoIP environments, the "Surveillance Mode" automatically adjusts QoS, IGMP snooping, and VLAN segmentation for optimal video performance. Dual firmware/configuration support ensures easy rollback and enhanced uptime. All ports are equipped with built-in 6 kV surge protection, shielding your network from power spikes

Product Key Features

• 24× 1 Gigabit RJ-45 ports plus 4× 10 Gbps SFP+ uplink slots for high-speed backbone connectivity

• Layer 2 + Lite Layer 3 features: VLAN, link aggregation, static routing, IGMP snooping, QoS

• Robust security: 802.1X authentication, ACLs, ARP spoofing prevention, D-Link Safeguard Engine
