D-Link DGS-1250-28X/E – Smart Managed Gigabit Switch with 24 RJ45 Ports and 4x 10G SFP+
General Information: The D-Link DGS-1250-28X/E is a Smart Managed switch from the DGS-1250 series designed for 19-inch rack mounting. It combines 24 Gigabit RJ45 ports with 4 SFP+ ports for 10Gbps in a compact housing.
Function: The 24 copper ports at 10/100/1000Mbps connect workstations and end devices, while the four SFP+ ports provide fast 10 Gigabit uplinks to servers, NAS systems or core switches. As a manageable Layer 2+ switch, it can be configured to match your network structure.
Applications: The switch is well suited to office and business networks, server rooms and network cabinets where many Gigabit clients need to be connected to the backbone, servers or storage via 10G links.
Material: The metal housing in 19-inch format with IP20 protection is designed for indoor use; cooling is handled by a smart fan.
Technical Details: At 440mm wide, 44mm high (1U) and only 140mm deep, the switch also fits shallow network and wall-mount cabinets. It operates at Layer 2+ without Layer 3 routing. Power over Ethernet is not available, and the power supply is single, not redundant.
Conclusion: The D-Link DGS-1250-28X/E combines 24 Gigabit ports and four 10G SFP+ uplinks in a manageable 1U device with a shallow mounting depth.

FAQ
How do I connect a server or NAS at 10Gbps?
Use one of the four SFP+ ports with a suitable SFP+ transceiver or DAC cable. These are not listed in the scope of delivery in the datasheet and should be planned separately.
Can I power access points or IP cameras directly from the switch?
No, the DGS-1250-28X/E does not support PoE. PoE devices need their own power supply, a PoE injector or an additional PoE switch.
Will the switch fit in a shallow wall-mount cabinet?
Yes, with 19-inch width and 1U height it requires only 140mm of mounting depth – plus space for the cables at the front.
