Thinkstar 24 Port PoE Gigabit Switch 28 Port 400W

SKU CH-S43Q-4DBQC

A 28-port unmanaged Gigabit PoE+ switch with 24 powered ports, 400 W budget, 30 W per port, 250 m reach and 4 kV surge protection

  • 400 W budget powers 24 PoE+ ports
  • 28 total gigabit ports including 2 SFP uplinks
  • 30 W per port for cameras and APs
  • 250 m extended reach with VLAN isolation
  • 4 kV surge protection in metal rack-mount chassis

28-Port Gigabit PoE Switch for IP Networks

This 28-port unmanaged switch provides 24 PoE+ ports with a 400 W total power budget and up to 30 W per port. Two additional Gigabit uplink ports and two SFP ports handle aggregate traffic. IEEE 802.3af/at compliance ensures automatic detection of powered devices. It suits installers deploying IP cameras, access points or VoIP phones.

Sustained Load Behaviour with AI Watchdog

The AI Watchdog function monitors connected powered devices continuously and restarts any that become unresponsive without manual intervention. PoE ports remain isolated from each other while communicating with the uplink ports, preserving bandwidth during constant streaming. A 250 m extended-distance mode supports long cable runs without signal degradation.

Thermals, Noise and Power in Normal Use

Sturdy metal housing acts as a passive heatsink for the internal 400 W power supply, allowing fanless operation in desktop or rack-mount installations. The 4 kV lightning protection design shields the switch and attached equipment from surge events. Plug-and-play deployment requires no software configuration, keeping operational overhead minimal.

Questions about this item

Does the 400 W power budget stay quiet and cool when all 24 PoE ports are loaded?

The switch has a 400 W internal budget with up to 30 W per PoE port; the metal housing acts as a heatsink and the unit is unmanaged, so fan noise and thermal load depend on how many ports draw full power.

What cables and powered devices must I already have to use the 24 PoE+ ports and 2 SFP uplinks?

You need Cat5e or better Ethernet cables for the 24 PoE+ ports and compatible SFP transceivers with fibre patch cords for the 2 SFP uplinks; the switch itself supplies up to 30 W per PoE port.

Will my older 802.3af access points and IP phones negotiate correctly with the 30 W PoE+ ports?

The ports are IEEE 802.3af/at compliant and automatically detect PD devices, so legacy 802.3af gear will negotiate at its rated class while newer PoE+ devices can draw up to 30 W.
