• Managed Layer 2 networks requiring VLAN, QoS, ACL, security, and centralized management
Connect Gates Recommendation:
• Connect Gates recommends the D-Link DES-3028P for projects that require a reliable managed PoE access switch for Fast Ethernet endpoints with Gigabit uplink capability.
• It is suitable for CCTV/IP surveillance, VoIP phones, wireless access points, SMB networks, schools, factories, and access layer cabinets where 24 PoE ports and managed Layer 2 control are required.
• The 24 PoE ports, 185W PoE budget, 4 Gigabit copper ports, 2 combo SFP slots, VLAN, QoS, ACL, IP-MAC-Port Binding, 802.1X, and D-Link Single IP Management make it a practical option for structured and secure network deployments.
• For best performance, Connect Gates recommends checking the total PoE load before installation and reserving the Gigabit copper or SFP ports for uplinks between cabinets, NVRs, servers, or backbone switches.
