It delivers Power over Ethernet across its gigabit access ports, allowing technicians to power IP cameras, wireless access points, VoIP phones, and other PoE-enabled devices without separate power runs. Four dedicated 2.5G uplink ports provide higher-bandwidth backbone connections to aggregation switches or core network equipment. Network engineers and IT infrastructure professionals handle installation and configuration of this unit in wiring closets and server room environments.\u003c\/p\u003e\u003cp\u003eThis switch is suited for structured cabling deployments in commercial buildings, multi-tenant facilities, and campus networks where centralized PoE distribution is required. The 2.5G uplink ports make it a practical choice for environments that need faster uplink capacity without a full 10G infrastructure investment. It fits into rack-mounted network closets and supports layer 2 smart managed features including VLAN segmentation, QoS prioritization, and link aggregation for optimized traffic flow.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e28 PoE-capable gigabit access ports for centralized device powering\u003c\/li\u003e\n\u003cli\u003e4 x 2.5G uplink ports for high-bandwidth backbone connectivity\u003c\/li\u003e\n\u003cli\u003eSmart managed feature set including VLAN, QoS, and link aggregation\u003c\/li\u003e\n\u003cli\u003eRack-mountable form factor for wiring closet and data room installations\u003c\/li\u003e\n\u003cli\u003eSuitable for powering IP cameras, WAPs, and VoIP endpoints via PoE\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification smart managed PoE switch for use in standard IEEE 802.3af and 802.3at PoE network deployments within commercial and enterprise edge environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified network engineers or low-voltage cabling technicians. The switch should be mounted in a grounded equipment rack using appropriate rack hardware before powering on. Ensure the power source meets the unit voltage requirements and that total PoE budget across connected devices does not exceed the switch rated PoE capacity. Follow applicable local electrical codes and TIA-568 structured cabling standards during patch panel and cabling termination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccess Ports\u003c\/strong\u003e: 28 x Gigabit PoE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUplink Ports\u003c\/strong\u003e: 4 x 2.5G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Switches and Routers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: D-Link Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DGS-1520-28MP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"D-LINK","offers":[{"title":"Default Title","offer_id":51686289015090,"sku":"DGS-1520-28MP","price":2915.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/d-link-dgs-1520-28mp-28-port-poe-gigabit-smart-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
