D-Link DMS-1250-10SPL Managed L2 Switch

Overview

The D-Link DMS-1250-10SPL is a managed Layer 2 switch designed for high-performance networking. It features 8 x 10/100/1000/2.5GBase-T ports with Power over Ethernet (PoE) capabilities and 2 x 10GBase-X SFP+ uplink ports, providing robust connectivity and flexibility for modern network infrastructures.

Key Features

• Multigigabit Solution: Supports 2.5 Gigabit Ethernet, offering double the bandwidth of Gigabit Ethernet without requiring cable replacement, facilitating easy integration of Wi-Fi 6 devices.
• High Performance: Equipped with two 10-Gigabit SFP+ uplink ports for high-throughput connections, essential for demanding network environments.
• Power over Ethernet (PoE): Features 8 PoE ports capable of delivering up to 30W (802.3af/at) or 60W (802.3bt/UPoE) per port, with a total PoE budget of 120W. This allows for powering devices like access points and network cameras directly over Ethernet cables.

Product Image Description
