Description

D-Link DES-1210-28P 24-Port Fast Ethernet PoE Smart Managed Switch

The D-Link DES-1210-28P is a Web Smart Layer 2 managed switch designed for small and medium businesses that need PoE delivery, VLAN control, and traffic prioritisation without the complexity of a full managed switch. It equips network administrators with 24 10/100 Mbps PoE ports, two 10/100/1000BASE-T Gigabit ports, and two Combo Gigabit/SFP ports for flexible upstream connectivity. Dlink IT teams deploying IP phones, wireless access points, and IP cameras across office environments will find it a cost-effective middle ground between unmanaged and enterprise-grade switching.
