I added another PoE powered AP (a TP-Link EAP615 wall mounted AP) in addition to an existing ceiling mounted TP-Link EAP610, and decided it was time to ditch the PoE injector on the EAP610 and power them both through this PoE switch - a much cleaner implementation in my home network rack than a PoE injector with its "wall wart" power brick and related device. Alternatively I could have gotten a smaller capacity multi-port desktop PoE switch, but that doesn't lend itself well to the limited capacity of my little 6U network rack and its tidy cable management. While this switch is a bit pricy, I like that it integrated with my software based Omada controller (running on a Windows always-on home server). This switch allowed me to easily identify everything connected to my wired and wireless networks (home network and VLAN based IoT network) using the Omada controller software GUI. I was a bit intimidated at first by the Omada controller and whether it would let me use it with my pFsense firewall, but it ended up being pretty quick and intuitive to set up, and everything coexists nicely. I've seen some complaints about fan noise - I have this rack mounted in my unfinished basement - the fans make some noise but nothing terrible, and certainly nothing that can be heard in the rest of the house. I'm not sure if fan noise is a fair criticism here - this is a fairly sophisticated device and not something that should be mounted in a living area IMO. This is really more small to medium sized business oriented, where it is likely to reside in a network closet where noise is a given. Given the excess PoE capacity this switch gives me, I will likely add the Omada OC200 hardware controller, as having the software running on a Windows machine means I'm subject to Windows' inevitable software updates and reboots. I tend to favor hardware implementations rather than software implementations anyway - running stuff on host machines and/or VMs is not ideal IMO. I'm pleased with this device - a nice "level-up" to my increasingly sophisticated home network, and the Omada SDN is an inexpensive alternative to other SDNs.

The product is great except for the loud fans. If it is going in a server room, then it will likely be fine. But in a residential setting you will notice the fans. I am going to deal with it with some Noctua fan replacements. I am only using about 15w for a POE load.

Technically this TL-SG2428P worked just fine. It was easy to set up, and I like that the management interfaces are clearly in a league above TP-Link's more consumer fare. SNMP also worked perfectly, which isn't always the case with TP-Link switches. However, I hadn't anticipated a couple of things about it: 1) It's surprisingly loud. It has fans. Very tiny, very high-RPM fans that spin at high throttle even when the switch is completely idle. Even though I placed this under my house, the fans are so loud & of such an irritating sound profile that I literally could not sleep with them running. My HVAC system makes less noise than this switch. I tried to 'get used to it' for two nights and gave up, exhausted, and simply returned it. 2) It draws a lot of power at idle - about 17W, even before you plug an ethernet cable in. That's ~150kWh per year. If you're actually going to use it under high traffic load, or a lot of the 250W PoE budget, then its idle power inefficiency is less of an issue. 3) I received a V2 version, which is grey market and not supported by TP-Link in the United States (only V1 & V4 are). Best I can tell V2s are intended for Japan. The fans can be replaced, it's true - the Noctua NF-A4x20 FLX seems quite popular, from researching online - but there's all sorts of caveats there (like, will it void the warranty, will the much-lower-CFM of the replacement fans cause the switch to overheat, etc). If you _don't_ actually need most of the ports running PoE, the 250W PoE budget, and full cross-sectional bandwidth, then you're better off going with e.g.: 1. The TP-Link TL-SG3428 (basically the PoE-less version of this but from the newer Jetstream 3000 series). 2. The TL-SG1210MPE. Those alternatives have no fans at all so they're virtually silent, and combined they only cost $30 more anyway (at time of writing). There's also various other options for adding on PoE to the TL-SG3428, like single-port PoE injectors for $15, if you only need a couple of PoE-enabled ports.

Great Price/Features/Ports combination. Ducking a star for the need to swap the fans. It is probably OK without the fans when you have low loads. A firmware that completely turns the fans off when temps are OK could have solved the issue. I have swapped fans in all TP link switches - no issues after a couple of years, but I do run low PoE loads. The swap probably voids the warranty too. The wiring is backwards, but instead of swapping the wires, carefully lift the white little base with the key tab from the PCB and flip it. Noctua fans plug in directly. You will still get a fan error though, unless you ground the tach input. All mods are at your own risk.
