Industrial embedded PoE+ switch module

The Brainboxes SW-125 is an embedded five-port Fast Ethernet switch designed for industrial automation and remote monitoring. It delivers both data and up to 30 watts per port on the first four ports, simplifying cabling for IP cameras, wireless access points and sensors. The module accepts redundant 44V to 57V DC inputs with reverse-polarity protection for reliable operation in harsh environments.

Wide-temperature fanless operation

Rated from -40°C to +70°C, the unit runs without moving parts and draws a maximum of four watts for its own logic. A 90W PoE budget is maintained across the full temperature range, so connected devices receive consistent power even at the upper limit. Dual redundant inputs keep the switch alive if one supply fails, while reverse-polarity protection guards against wiring errors.

No bundled software or accessories

The product ships as a bare circuit-board module intended for integration into a larger enclosure or DIN-rail carrier. No configuration utility, mounting hardware or power supply is included, so system builders must provide their own DC source and mechanical housing. Management is handled through standard IEEE 802.3af/at negotiation rather than a proprietary tool set.

Questions about this item

How do I install the SW-125 and what wiring mistake should I avoid?

Mount the embedded module, connect the two redundant DC inputs between 44V and 57V observing polarity, then plug Ethernet cables into the five 10/100 ports; the dual inputs are reverse-polarity protected but crossing the positive and negative leads on either input will still prevent power-up.

What maintenance or replacement will the SW-125 need over time?

No moving parts or fan are present; keep the operating ambient between -40°C and +70°C and verify the 90W PoE+ budget across ports 1-4 is not exceeded, as sustained overload is the only factor that degrades the internal DC-DC converters.

What limit appears first when the SW-125 runs continuously at full load?

The 90W PoE+ power budget at 70°C is the first constraint; if all four PoE+ ports draw near 30W each the budget is reached before the 100Mbps port speed or the 4W switch overhead become bottlenecks.
