Compact 2.5 GbE switch for dense multi-gig

The USW-Flex-2.5G-8 is a managed Layer 2 desktop switch with eight 2.5 GbE RJ45 ports and a 10 Gb SFP+ or RJ45 combo uplink. It targets installers who need high-density 2.5 GbE connectivity for Wi-Fi 6 access points, cameras and IoT endpoints in a small footprint.

Sustained throughput and forwarding under load

Non-blocking throughput reaches 30 Gbps with a switching capacity of 60 Gbps and a forwarding rate of 45 Mpps. Layer 2 features such as STP, RSTP, storm control, multicast and broadcast rate limiting, port isolation, mirroring, jumbo frames and loop protection maintain stability during continuous heavy traffic.

Fanless thermals and dual power options

The fanless aluminium enclosure operates silently while dissipating up to 14 W whether powered by the included 5 V 3 A USB-C adapter or a PoE+ source. Its compact 212.9 x 76 x 33.5 mm form factor and 395 g weight allow discreet placement in tight spaces without active cooling noise.

Questions about this item

How much power and heat does the USW-Flex-2.5G-8 produce when running continuously?

Maximum consumption is 14 W with PoE+ input, and the same 14 W with the USB-C adapter, so heat output stays low in continuous use.

What must I already have to manage and power this switch?

You need a UniFi Network controller running version 9.0.114 or later, plus either a PoE+ injector or the included 5 V 3 A USB-C adapter.

Will the 2.5 GbE ports and 10 GbE uplink work with my existing 1 GbE cameras and Wi-Fi 6 access points?

Yes, all ports auto-negotiate down to 1 GbE, so legacy devices connect normally while Wi-Fi 6 APs can use the full 2.5 GbE speed.
