Davuaz Da-K9801W Management
This is an unmanaged switch. We could not find a management interface. For a switch in this price range, perhaps that is exactly what folks want.
Davuaz Da-K9801W Performance
In terms of performance, this seems to be a decent, but not top-tier performer.
Again, for a sub $90 switch this is not bad. It is also virtually identical to others we have tested with this chipset combination.
Davuaz Da-K9801W Power Consumption
Power adapters are always an interesting point. This comes with a few markings but we do not see things like FCC or CE markings. That is pretty common for this class of switch. It is only a 12V 1A power adapter, so we know this is going to be a low-power device.
At idle, we got around 2.3W at idle with nothing attached.
With a single 2.5GbE port plugged in, we added 0.7W for 3.0W total.
We used a 10Gbase-T SFP+ pluggable to add a good amount of power consumption in a SFP+ port and we got 3.7W for 1.4W over our baseline.
As with other low-power switches, we tried powering this over PoE using a splitter, and it worked. While this does not have PoE-in, a cheap splitter got us the power we needed to the switch just given it is such a low-power device. Perhaps that is not the best idea, but it worked for the “PoE everything” crowd.
Final Words
Again, we do not get a lifetime warranty, regulatory markings, or similar. Still, it is cheap, but not that cheap. Class-leading pricing of the 8+1 Realtek solution is usually sub $80. This is one to perhaps add to the list to look at, but if it is not on sale, others probably will be.
This is not a switch we would pay a premium for, but it worked, and it was new and different, so it felt interesting. That is really part of this series which is to look at lower-cost switches that bring 2.5GbE to much lower price points.
Small, cheap, and fanless make this a useful tool. This is not the highest-quality switch on the market by any means, but it is also not trying to be. Instead, this is really a switch competing on pricing.

You may have seen that we published the Ultimate Cheap Fanless 2.5GbE Switch Buyer’s Guide. Here is the video for that one where this switch appeared.
We decided to do the round-up first and will be filling in with reviews that we had not published at that point, including this one. We are trying to keep everything in a single resource for folks there.
