TP-Link Omada SG6428XHP L3 PoE Switch

The Omada SG6428XHP combines full Layer 3 routing with serious PoE delivery: 24 Gigabit PoE+ ports, four 10 Gbps SFP+ slots and up to 720 W of total PoE budget, with physical stacking and dual field-replaceable power supplies for genuine high availability.

It is the switch for a distribution layer that also powers devices directly — dense deployments of access points such as the EAP660 HD or Wi-Fi 7 EAP772 — all under Omada SDN cloud management with a controller such as the OC300.

Key features

• 24 × Gigabit RJ45 PoE+ ports with up to 720 W total PoE budget.
• 4 × 10 Gbps SFP+ slots for high-bandwidth uplinks.
• Physical stacking for built-in redundancy and performance.
• Layer 3 routing — RIP, OSPF, ECMP, VRRP, PIM-DM and DHCP server/relay.
• Security strategies — ACL, port security, DoS defend and 802.1X.
• High availability — two field-replaceable power supplies, VRRP and ERPS.
• Omada SDN cloud management plus standalone web, CLI, SNMP and RMON.

Works with

• TP-Link EAP660 HD — high-density Wi-Fi 6 AP powered over PoE+
• TP-Link SG6428X — the same L3 platform without PoE
• TP-Link Omada OC300 controller for SDN management
• All network switches
• All networking

Frequently asked questions

Why choose an L3 PoE switch?

It collapses two roles into one box: inter-VLAN routing with OSPF, RIP, ECMP and VRRP, and PoE+ power for the access points, cameras and phones connected to it — fewer devices, fewer hops.

How resilient is it?

Very — two field-replaceable power supplies, VRRP for gateway redundancy, ERPS ring protection, and physical stacking so a failed unit does not take down the layer.

What can the PoE budget power?

Up to 720 W in total across 24 PoE+ ports — enough headroom for a full complement of high-power wireless access points with room to spare for cameras and phones.

Do I need an Omada controller?

No — it manages standalone via web, CLI, SNMP and RMON; Omada SDN controllers add centralised cloud management when you want it.
