  • FeaturesAccess Control List Broadcast Storm Control Safeguard Engine
  • 18 ports including 2.5G and 10G uplinks for high-speed aggregation
  • 370 W PoE budget powers cameras and access points without extra injectors

  • ACL, DHCP snooping and ARP inspection harden the network edge
  • Dual firmware images and surge protection keep services running during updates or spikes

18-Port 2.5G L2 PoE Switch

The D-Link DMS-1250-18P is an 18-port manageable switch delivering 2.5 Gigabit Ethernet over twisted pair and 10 Gigabit Ethernet over optical fiber. It provides a 370 W PoE budget to power connected devices and operates at 443.84 W total power consumption. Layer 3 static routing is supported for network segmentation.

Managed networks needing PoE

This switch suits administrators who require 2.5GBase-T connectivity with PoE for access points or cameras and need Layer 3 routing features. It is not for buyers who need higher port density beyond 18 ports or a larger PoE budget than 370 W. It also does not fit environments requiring fanless silent operation.

370 W PoE budget decides fit

The single specification that determines suitability is the 370 W PoE budget across the 16 PoE-enabled ports. If the total power draw of all powered devices exceeds this limit, the switch cannot support the deployment. Verify the combined wattage of every attached PoE device before purchasing.

Questions about this item

Will the 16 2.5GBase-T ports and 2 10GBase-X uplinks work with my existing 1 Gbps servers and Cat5e cabling?

Yes, each 2.5GBase-T port auto-negotiates down to 1 Gbps so current 1 Gbps NICs and Cat5e cables connect directly. The two 10GBase-X uplinks accept compatible SFP+ modules for fibre links to older 10 Gbps core switches.

Which front-panel LEDs confirm the switch is passing traffic and delivering PoE on all 18 ports?

Each port shows a link/act LED for 2.5G or 10G connectivity and a separate PoE LED that lights when a powered device is drawing from the 370 W budget. The system LED stays solid green once the dual-image firmware has booted without errors.

What ships with the DMS-1250-18P and what must I purchase separately for fibre uplinks?

The box contains the switch, a rack-mount kit, a power cord and a quick-install guide. SFP+ transceivers for the two 10GBase-X uplink ports are not included and must be bought separately.
