24-Port Layer 2 Switch for Silent Deployments

The USW-24 provides 24 Gigabit RJ45 ports and two 1G SFP uplinks in a fanless, rackmount chassis. It delivers 26 Gbps non-blocking throughput with a 52 Gbps switching capacity for small to medium networks that need managed Layer 2 features without acoustic noise.

Sustained Load Behaviour with Fanless Cooling

Without fans, the switch relies on passive convection to dissipate up to 25W of power consumption across its operating range of -5 to 45°C. The 36W internal supply handles continuous 1Gbps line-rate traffic on all ports while maintaining silent operation in noise-sensitive environments.

Practical Limits of 1G SFP Uplinks

The two 1G SFP ports constrain uplink aggregation to 2 Gbps total, which can become a bottleneck when multiple 24-port access switches feed a single aggregation layer. Networks requiring 10G uplinks or PoE power for connected devices must select a different model.

Questions about this item

How much heat and noise does the fanless USW-24 produce when running 24/7?

The switch uses a fanless design for silent operation and has a maximum power draw of 25W, so heat output stays low even under continuous load.

What cabling or modules do I need to use the two SFP ports on this switch?

You will need compatible 1G SFP transceivers and the matching fibre or copper patch cables for the link distance you require.

Can I connect the USW-24 to my existing 10/100 Mbps devices without configuration issues?

Yes, the 24 RJ45 ports auto-negotiate down to 10/100 Mbps, so legacy devices work immediately on this Layer 2 switch.
