This week, we have another 4-port 2.5GbE and 2-port SFP+ 10G switch from Yuanley. One of the more interesting features is that this also has PoE capabilities, which many do not have. Even with PoE, we purchased this switch for only $59, making it one of the cheaper 2.5GbE and PoE switches out there.
If you want to check the current pricing, we purchased this from Amazon. Here is an affiliate link to the one we bought.
Yuanley YS25-0402P Overview
We first covered this switch in our 2024 Mega round-up, which you can find here:
We have also added this switch to the Ultimate Cheap Fanless 2.5GbE Switch Buyer’s Guide, which lists 40+ models. Bookmark that page to get the latest. We will like all of these reviews from that page.
Yuanley YS25-0402P Hardware Overview
On the front of the switch, one can see four 2.5GbE ports and two SFP+ 10GbE ports. The big difference is that the four 2.5GbE ports are PoE+ (af/at) capable.
This switch did not come with rackmount ears, but if you wanted to get creative, you could fit them via the mounting holes.
On both sides, there are vents.
The rear has an AC power input and a grounding point. This switch has an internal power supply, which is something that we did not see on these switches 12-18 months ago, but it is starting to become more common. We saw the sibling of this switch in the Nicgiga S25-0402P PoE 2.5GbE and 10GbE switch we reviewed.
On the bottom, we get a standard label and wall mounting points. This label says 78W max output.
Inside the switch, we can see one of the larger 4+2 boards, and the internal power supply is next to it.
Here is a view of the board and the power supply.
The heatsink on the Realtek switch chip is very small and the switch board seems to be the same as the Nicgiga switch.
Although the internal PSU is labeled as a V7.0 PSU, it is probably not the fanciest we have seen. However, we did see something else: It is only a 75W PSU. Remember the label says that the switch has 78W of PoE output, and the switch itself, without counting PoE device power, also takes some of that capacity. It feels like for a switch advertising 78W of PoE output, it should have a PSU bigger than 75W. This is the same as the Nicgiga switch.
Next, let us get to management, performance, and power consumption.
So, while it’s unmanaged, what does it do with VLAN tagged packets? If it passes them would be great for hooking up APs.
Damn. I missed this on the previous switch review, but is that among the cheapest power supplies possible! Not in a good way! There’s a fuse, so it’s got that going for it. However, the AC input front end just has MOVs for overvoltage protection and a single filter cap (yellow) before the bridge rectifier. There should be at least one common mode choke for filtering with the filter cap (and more caps, too). The big bridge rectifier and AC-side transistor heatsink are probably fine. The output having a single device with a big heatsink probably means it’s just a diode rather than the more efficient synchronous rectification transistor (MOSFET) that only makes sense from the high output voltage of the PoE supply. Whole thing’s probably hot, noisy, and of questionable reliability. Now cheap!
For what good PSUs look like, consider TechPowerUp’s ATX PSU reviews and ChargerLab’s wall charger teardowns/component analysis.
For these cheap switches, I would prefer an external adapter for power. At least I can then replace it easily when it fails or when I don’t trust it’s safety.
