The Ubiquiti USW-Pro-Max-16-PoE occupies an awkward middle ground between a central rackmount switch for an entire building and the smaller Flex switches aimed at prosumer or satellite use cases. The sixteen ports are split unevenly: four run at 2.5GbE with PoE++, while the remaining twelve are 1GbE only, which means you need to think carefully about what gets plugged in where. Two SFP+ ports provide 10GbE capability, and the fanless design is a genuine plus for closet installations. In my setup it serves as a secondary closet switch with 10GbE uplinks in both directions, but for most use cases one of the Flex 2.5GbE 8-port models will be a better fit. The niche this switch fills is real but narrow.

The Port Layout

All sixteen RJ45 ports support at least PoE+, with four of them stepping up to PoE++. Those same four ports are 2.5GbE, while the remaining twelve are 1GbE only. Two SFP+ ports round things out with 10GbE capability.

This split design means you need to think carefully about what gets plugged in where. If you need more than six fast ports, you’re out of luck. If you only need six or less, you should probably buy something else entirely.

My Use Case

This switch lives in a secondary network closet. One SFP+ port provides a 10GbE uplink to my main network room over existing copper cabling—I would have used fibre if I’d had the option to run it. The other SFP+ port feeds 10GbE to my office, where it connects to the single 10GbE port on a 2.5GbE Flex switch until I can get a 10GbE Flex Mini.

The four 2.5GbE ports serve clusters of hardware where the faster network speed is useful. The remaining 1GbE ports handle a handful of connections to things like printers, where infrequent use makes speed irrelevant.

Physical Design

The fanless design is a genuine plus for a closet installation—no noise to worry about, but more importantly, less heat to build up. However, the LED display and etherlighting feel out of place in what is basically a normal closet. These are features designed to look impressive in a visible rack, not hidden behind a closet door.

Downsides

  • No PoE input: You can’t power the switch itself with PoE, so you’ll need a separate power run to wherever it’s installed.
  • Port allocation headaches: With only four 2.5GbE/PoE++ ports and twelve 1GbE ports, you need to be deliberate about what goes where for both speed and power delivery.
  • Boot time: The switch takes a surprisingly long time to start up. Several minutes, in fact. Plan accordingly for power outages or firmware updates.

Verdict

The only real use case for this product is where you need more than eight 1GbE ports, some 2.5GbE ports but not more than six (or four with PoE++), and you need two 10GbE or 10G fibre connections instead of just one.

For almost all cases, one of the Flex 2.5GbE 8-port models (non-PoE or PoE ) will be better. For 5% of the remaining use cases, two Flex 2.5GbE switches and a short patch cable will still be better. For the final 5%, where you genuinely need a second 10GbE link, this will work. Just don’t be surprised by the 4 × 2.5GbE / 12 × 1GbE split, and make sure you only need four or six fast ports.

And you won’t need a motion-detector light in your closet anymore.
