D-Link 24-portový Gigabit PoE Smart Managed Switch s 4x 10G SFP+, 370 Watt

The D-Link DGS-1250 Series Smart Managed Switches provide an enterprise-grade access and SMB aggregation solution with multiple physical interfaces, full CLI via a console port, web management in 11 languages, QoS, and advanced Layer‑2 with lite Layer‑3 capabilities. Models are available with 24 or 48 Gigabit Ethernet ports plus an additional 4 x 10G SFP+ slots for optical uplinks, supporting multimode and single‑mode SFP transceivers. These switches are designed to deliver reliable performance and flexible connectivity at a value price.

Advantages

The series includes Dual Image and Dual Configuration support and a console port for simplified maintenance and reduced downtime. Full CLI enables remote configuration without Internet access, while STP/RSTP/MSTP support preserves network stability during topology changes. Auto Voice VLAN and Surveillance Mode automatically identify and prioritise VoIP and video traffic. Select PoE models offer a high power budget (up to 370 W) and support IEEE 802.3af/at standards, allowing centralized power management for IP cameras, VoIP phones and wireless access points. Management tools include IGMP snooping, port mirroring, LACP, IEEE 802.3x Flow Control and static routing for inter‑VLAN communication, plus the D-Link Network Assistant for device discovery and port‑level control.

How to use

Install the switch in a standard 19‑inch rack or place it on a flat surface. Connect client devices to the 10/100/1000BASE‑T ports and uplinks to aggregation or core switches via the 10G SFP+ ports using compatible SFP transceivers. Access the web GUI or CLI through the console port for initial configuration, or use D-Link Network Assistant to discover devices on the same L2 segment. Configure VLANs, QoS policies, PoE settings and link aggregation as required. Enable STP/RSTP/MSTP to maintain loop‑free operation and use Auto Voice VLAN or Surveillance Mode to prioritise voice and video traffic. For remote administration, use supported management interfaces and secure access methods.

Recommendations

Choose a PoE model when deploying IP cameras, VoIP phones or wireless access points to simplify cabling and centralized power management; verify the required PoE budget per model and plan uplink capacity using 10G SFP+ transceivers appropriate for multimode or single‑mode links.
