Hi, HWBusters community,

I wanted to share my thoughts and ask for your input on the Ubiquiti USW-PRO-24-POE-400W, a 24-port Layer 3 managed switch with full UniFi integration. It's a recent addition to my home lab, and so far it's been impressive—especially for setups that demand both power and control.

Key Specs:

• 24 Gigabit RJ45 ports with 802.3af/at/bt PoE support (PoE++ capable)

• 2 10G SFP+ uplink ports

• Layer 3 routing features (inter-VLAN routing, static routes)

• 400W total PoE budget

• UniFi Controller required for full feature access

• Silent, fanless design with passive cooling

My Use Case:

I'm using it to power a mix of UniFi APs (U6-Pro), cameras, and a couple of MikroTik and non-Ubiquiti PoE devices. So far, the power draw stays well below the 400W ceiling, and the switch seems to handle everything without getting warm. VLAN setup was straightforward through the UniFi Controller, and the 10G uplinks are currently running to a Proxmox server via DAC cables.

Pros:

• Solid build and rack-mountable

• Easy VLAN and L3 configuration via UniFi

• Silent (great for home/office setups)

• High PoE budget with bt (PoE++) support

Cons:

• Requires UniFi Controller to unlock full functionality

• Limited Layer 3 features (no dynamic routing like OSPF/BGP)

• No CLI—GUI only (could be a pro or con depending on preferences)

Questions for the community:

1. Has anyone stress-tested the full 400W PoE output long-term?

2. Any known reliability issues or firmware quirks I should be aware of?

3. Anyone integrating it with non-UniFi gear at scale?

Would love to hear your setups or thoughts on similar L3 PoE switches that compete with this one. Also curious about performance under heavier VLAN and multicast loads, if anyone has experience.
