what it is

A switch for a desk or behind a cabinet: five gigabit ports, chassis 107 × 70 × 21 mm, weight 150 g. Powered by PoE through port one or by a regular USB-C power adapter. Draws up to 2.5 W.

Port one accepts power, but no port supplies it. A switch powered from another switch's port goes dark together with that port — and with it everything behind it.

what we read from it

266 parameters from the controller interface. Fewer than from a rack switch, and that is expected — this model has no PoE output, no fiber transceivers and no temperature sensor.

Even so, we can see:

The state of each of the five ports separately — whether the link is up, at what speed and in what duplex.
Link drop counter — the same as in a large switch.
Uptime since power-on. When powered from someone else's PoE port, a switch restart may be the only trace that someone turned off or overloaded that port.

what to watch out for

There is no cable test. The UniFi Network 10.6.106 controller has no such function at all.

what we cannot read

Temperature — this model has no sensor. This is a hardware limit.
PoE output — there is none; port one accepts power, it does not supply it.

full parameter list from the controller interface

The list shows WHAT the device exposes — including parameters we do not use ourselves. There are no values here at all: it is a catalog of capabilities, not a reading from anyone's network. It is not a closed list either — explanation below the table.

This is not a closed list. It comes from reading a unit we had access to — it shows what we managed to retrieve, not everything the device can return. A different firmware version, hardware variant or reading path can expose fields that are not here. If you are interested in a specific unit and a specific value — please ask; there is a good chance it can be obtained, even if you do not see it below.

List source: reading of 1 working unit (as of 2026-09-27). The list is the sum of what we observed — more units reveal more parameters, so numbers for different models are not directly comparable.

SNMP: the device has no SNMP agent (verified with a probe)

This device has no SNMP agent: port 161 answers with “port unreachable”, just like a port with nothing running on it (verified with a probe, with a control test on another switch). Data for this model can only be read from the controller.
