D-Link DXS-1250-28YP 28-Port 10GbE Smart Managed PoE++ Switch

10GbE Access With Power for the Edge The DXS-1250-28YP brings 24 multigigabit 10GBASE-T PoE++ ports and four 10/25G SFP28 uplinks into one managed switch. It suits demanding wireless access, connected systems and business networks that need both faster wired access and a planned PoE power budget. Each powered port supports up to 60W within the shared 470W budget. VLANs, access controls, link aggregation and static routing provide practical tools to separate traffic and manage local network connections without treating the switch as an internet security gateway. Highlights High-Speed Access 24 × 100M/1G/2.5G/5G/10GBASE-T PoE++ ports. 4 × 10/25G SFP28 uplinks. 680 Gbps switching capacity and up to 505.92 Mpps forwarding. Managed Power IEEE 802.3af/at/bt up to 60W per port. 470W shared PoE budget. Perpetual PoE and Fast PoE. Network Control VLANs, ACLs, 802.1X and IPv4/IPv6 static routing. Web administration, CLI and SNMP. 5-year warranty. Key Features Give Faster Endpoints a Faster Link Twenty-four copper ports support rates from 100 Mbps through 10GbE, allowing compatible access points, workstations and connected systems to use a suitable wired link. The negotiated speed depends on both endpoint and cabling. For longer 10GBASE-T runs, use cabling specified for the required distance rather than assuming an existing link will perform at 10GbE. Keep Uplinks Ready for More Traffic Four SFP28 slots support 10G and 25G uplinks to compatible core, server or storage equipment. Match supported optics or direct-attach cables, wavelength, fibre and distance at both ends. These connections provide useful capacity for aggregated traffic; the necessary modules and cables are selected separately. Power Devices Within a Clear Budget IEEE 802.3af/at/bt support delivers up to 60W per copper port within a 470W total budget. Add the actual endpoint power requirements before deployment. Twenty-four ports at their individual maximum would exceed the shared budget, and cable losses affect the power available to each connected device. Support Power Continuity During Maintenance Perpetual PoE can retain power to supported powered devices during switch restart, while Fast PoE starts supplying power without waiting for the full operating system boot. These features help with planned maintenance but do not provide battery backup or protection against loss of the switch power source. Separate Services and Control Access 802.1Q VLANs, Voice VLAN, multicast controls, ACLs and 802.1X help administrators organise devices and apply site policies. IPv4/IPv6 static routing supports selected local networks. Configure these functions alongside the upstream router and firewall, with management access restricted to authorised administrators. Install With the Environment in Mind Two smart fans provide temperature-aware cooling in the rackmount chassis. Six-kilovolt surge protection is specified on copper Ethernet access ports, with proper installation and grounding still required. Allow suitable airflow and ambient conditions; electrical protection does not make the switch weatherproof or guarantee immunity to every surge. Summary The DXS-1250-28YP combines multigigabit 10GbE access, 25GbE uplinks and managed PoE++ power for demanding business networks. Specify the cabling, optics and endpoint power budget together to make full use of the installation. Frequently Asked Questions Can Every Port Deliver 60W at Once?ExpandCollapse No. Each powered copper port supports up to 60W, but all ports share a 470W budget. Plan the total demand of connected devices and allow for the applicable Ethernet power standard and cable losses. Are All Copper Ports 10GbE?ExpandCollapse The 24 copper access ports support 100 Mbps, 1GbE, 2.5GbE, 5GbE and 10GbE. The actual negotiated speed depends on the connected device and cabling. What Connects to the SFP28 Slots?ExpandCollapse The four uplink slots support compatible 10G/25G optical transceivers or direct-attach connections. These parts are purchased separately and must match the link design. Is This a Full Dynamic-Routing Switch?ExpandCollapse The published Layer 3 capability includes IPv4/IPv6 static routing. Do not assume the dynamic-routing feature set of a different enterprise switch. Does Perpetual PoE Provide Backup Power?ExpandCollapse No. It supports endpoint power continuity during supported switch-restart operations. It does not replace a UPS or keep devices powered when the electrical source is lost. Can It Be Managed Locally?ExpandCollapse Yes. Browser administration, a CLI and SNMP are supported, with an RJ-45 console for out-of-band CLI access. Use secure management settings and the appropriate supported firmware. 더 보기
