D-Link DMS-1250-28 28-Port 2.5GbE Smart Managed Switch
A Faster Foundation for Everyday Business Traffic The DMS-1250-28 brings 2.5GbE access to workspaces with faster wireless access points, capable desktops and shared storage. 24 × 2.5GbE access ports and 4 × 10G SFP+ uplinks. This gives busy access networks a clear path to faster local transfers while retaining high-speed connections to the network core. Connect separately powered devices without paying for a PoE power system that the installation does not need. VLANs, access controls, link aggregation and IPv4/IPv6 static routing give administrators practical tools to segment traffic and keep shared infrastructure organised. Highlights Connectivity 24 × 2.5GbE access ports and 4 × 10G SFP+ uplinks. 200 Gbps switching capacity and up to 148.81 Mpps forwarding. Data-only switching; this model does not supply PoE power. 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 24 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 4 × 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. Straightforward Data-Only Switching This is the non-PoE model. It suits computers, NAS systems and other devices with their own power supply. Access points or cameras that require PoE need a separate compatible injector or powered switch; the data ports alone do not provide electrical power. Separate Services With Confidence 802.1Q VLANs, Voice VLAN and Auto Surveillance VLAN help organise users and applications.

Frequently Asked Questions Does This Model Supply PoE Power?ExpandCollapse Data-only switching; this model does not supply PoE power. Choose a PoE model or add a compatible injector when the endpoint needs power over Ethernet. Which Ports Support 10GbE?ExpandCollapse 4 × 10G SFP+. The 24 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.

Key Features
More Bandwidth at the Access Layer
24 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
4 × 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.
Straightforward Data-Only Switching
This is the non-PoE model. It suits computers, NAS systems and other devices with their own power supply. Access points or cameras that require PoE need a separate compatible injector or powered switch; the data ports alone do not provide electrical power.
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
2 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.

The D-Link DMS-1250-28 combines 24 multigigabit access ports, 10GbE uplinks and practical smart management for a capable data-only network.
Frequently Asked Questions
Does This Model Supply PoE Power?
Data-only switching; this model does not supply PoE power. Choose a PoE model or add a compatible injector when the endpoint needs power over Ethernet.
Which Ports Support 10GbE?
4 × 10G SFP+. The 24 access ports run at up to 2.5GbE, so they are not 10GbE access ports.
Can I Reuse Existing Ethernet Cabling?
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?
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?
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?
No. This exact model has 2 internal fans. Cooling behaviour depends on temperature and operating conditions; do not install it as a guaranteed silent or fanless device.
