TP-Link TL-SG3428 24-port Gigabit network switch with 4 SFP slots

SKU CH-74KY-XPA4Y

A 28-port managed switch with 24 Gigabit RJ45 ports, 4 SFP slots, L2+ features and Omada SDN cloud management

  • Switch Typemanaged
  • 24 Gigabit RJ45 ports plus 4 SFP slots deliver 28 high-speed connections
  • Omada SDN integration enables centralised cloud management from a single interface
  • Advanced L2+ features include static routing and Layer 2/3/4 QoS for traffic control
  • Security tools such as 802.1Q VLAN and IP-MAC-Port binding protect the network
  • QoS support ensures responsive performance for video conferencing and time-sensitive applications

Business-Grade 28-Port Switch

The TP-Link TL-SG3428 provides 24 Gigabit RJ45 ports and 4 Gigabit SFP slots in a single managed unit. It delivers Layer 2+ capabilities including static routing, QoS across L2/L3/L4 and link aggregation. The switch integrates with the Omada SDN platform for centralised control via hardware controller, software controller or cloud access. Security features include 802.1Q VLAN, IP-MAC-Port binding and ACL support.

Suits SDN-Managed Campus Networks

This switch fits organisations that want unified management of switches, access points and gateways through Omada SDN. It serves sites needing 24 copper endpoints plus fibre uplinks with advanced traffic prioritisation for voice and video. Networks requiring Layer 3 dynamic routing protocols or Power over Ethernet on the RJ45 ports will not find those functions here. Buyers needing only basic unmanaged connectivity should consider simpler devices.

24 RJ45 Plus 4 SFP Port Count

The decisive specification is the 28-port Gigabit configuration: 24 fixed 10/100/1000 Mbps RJ45 interfaces and 4 SFP slots for fibre modules. This exact port mix determines whether the switch matches your cabling plan and uplink strategy. No other port counts or speed grades are available on this model.

Questions about this item

How do I install the TL-SG3428 and which step is commonly missed?

Mount the switch in a standard rack using the supplied brackets, then connect the 24 RJ45 ports and 4 SFP slots; the step often missed is enabling the Omada SDN controller before configuring VLANs and static routes.

What maintenance or replacement will the TL-SG3428 need later?

The fanless design has no moving parts to replace; only firmware updates via the Omada controller or web interface are required to maintain security features and SDN compatibility.

What limit appears first under sustained heavy load on the TL-SG3428?

The 28-port Gigabit non-blocking fabric handles full wire-speed traffic, so the first limit is the 1000 Mbps per port ceiling when multiple 10/100/1000 clients saturate their links simultaneously.
