D-Link DMS-1250-18P 18-Port 2.5GbE Smart Managed PoE++ Switch

Multigigabit Access With Power to Grow The DMS-1250-18P brings 2.5GbE access to workspaces with faster wireless access points, capable desktops and shared storage. 16 × 2.5GbE PoE++ access ports and 2 × 10G SFP+ uplinks. This gives busy access networks a clear path to faster local transfers while retaining high-speed connections to the network core. Power and network connectivity share the same Ethernet cable, helping organise access-point and camera installations without separate local power adapters. VLANs, access controls, link aggregation and IPv4/IPv6 static routing give administrators practical tools to segment traffic and keep shared infrastructure organised. Highlights Connectivity 16 × 2.5GbE PoE++ access ports and 2 × 10G SFP+ uplinks. 120 Gbps switching capacity and up to 89.29 Mpps forwarding. IEEE 802.3af/at/bt on all 16 access ports, up to 90 W per port within a 370 W shared budget. Network Control 802.1Q VLANs, link aggregation, STP/RSTP/MSTP and ERPS. Web administration, CLI and SNMP monitoring. 6kV surge protection on 2.5GbE access ports. Key Features More Bandwidth at the Access Layer 16 ports support 100 Mbps, Gigabit and 2.5GbE operation. Compatible multigigabit access points and workstations can use faster wired links without forcing every device on the network to change at once. Link speed still depends on the connected equipment, cable quality and configuration. Uplinks That Suit the Network 2 × 10G SFP+ provide dedicated high-speed paths to a compatible core switch, server or storage system. Choose compatible optics or direct-attach cables for the required distance and endpoint. Transceivers and connection cables are selected separately. Power Matched to the Deployment All 16 access ports support IEEE 802.3bt up to 90 W per port, alongside 802.3af/at devices. The 370 W shared budget is the overall limit, so a power plan should use each device’s maximum requirement rather than multiplying every port by 90 W. Fast and Perpetual PoE support suitable device start-up and switch-reboot scenarios. Separate Services With Confidence 802.1Q VLANs, Voice VLAN and Auto Surveillance VLAN help organise users and applications. ACLs, 802.1X, DHCP snooping and IP-MAC-Port binding provide additional access controls. Configure these features to the site’s policies rather than relying on an unmanaged shared network. Practical Resilience and Local Routing LACP link aggregation, spanning-tree protocols and ERPS support planned redundant network paths. IPv4 and IPv6 static routes can connect selected local networks without treating the switch as a full enterprise router. The published limits are 128 IPv4 and 64 IPv6 static route entries. Management That Supports Ongoing Care 3 internal fans support temperature-aware cooling; keep the airflow paths clear. Web administration, CLI and SNMP provide options for configuration, monitoring and diagnostics. Dual firmware images and configuration files support a more controlled maintenance process. Summary The D-Link DMS-1250-18P combines 16 multigigabit access ports, 10GbE uplinks and practical smart management with a 370 W PoE budget. Frequently Asked Questions Does This Model Supply PoE Power?ExpandCollapse IEEE 802.3af/at/bt on all 16 access ports, up to 90 W per port within a 370 W shared budget. The full per-port rating is not available on every port simultaneously; remain within the total budget. Which Ports Support 10GbE?ExpandCollapse 2 × 10G SFP+. The 16 access ports run at up to 2.5GbE, so they are not 10GbE access ports. Can I Reuse Existing Ethernet Cabling?ExpandCollapse Suitable Cat5e or better cabling supports the specified 2.5GbE access links up to 100 m, subject to cable quality and installation. Test existing cabling before relying on the highest link rate. Does It Support VLANs and Static Routing?ExpandCollapse Yes. It supports up to 4,094 static VLAN groups, plus IPv4 and IPv6 static routes. The route table supports up to 128 IPv4 and 64 IPv6 entries. These capabilities do not make it a full dynamic-routing or firewall gateway. Is This a Physically Stackable Switch?ExpandCollapse This model is a smart managed switch with high-speed uplinks. Do not treat the uplinks alone as a physical stacking feature. Use link aggregation or a separately specified stackable family when the design requires a single managed physical stack. Is It Fanless?ExpandCollapse No. This exact model has 3 internal fans. Cooling behaviour depends on temperature and operating conditions; do not install it as a guaranteed silent or fanless device.
