UGREEN UM106X CM753 Management
This is an unmanaged switch, but there is the front toggle.
The VLAN position gives us port isolation. The Link Aggregation position turns the two ports into a link aggregation mode. These days, most folks buying in this class will use SMB3 Multi-channel, so this is less exciting than it would have been several years ago. This is not management, but there are some extra functions here.
UGREEN CM753 Performance
With this switch, we wanted to take out Keysight CyPerf machine and test the switch. Specifically, we wanted to see what would happen if we took four 2.5GbE ports on one side to the 10G SFP+ port on the other and get full performance. A small quirk is that we now have six 400GbE ports on our traffic generation machine, but only four 2.5GbE ports. Adding a 5th 2.5GbE port is possible, but it requires a non-standard configuration. Still, we just went for the four and one test.
Here we got Layer 2/3 throughput of around 19Gbps, which is bi-directional traffic across those ports. An interesting note is that as we crossed 512 users, we saw the switch start to run into challenges.
One item we wanted to see was how that 19Gbps or so was distributed across ports. We wanted to know if there was a 2.5GbE port that was slower, or if this was an even split. It looks like the 2.5GbE ports were hitting 2.37Gbps and the 10GbE port was at 9.48Gbps which is nice to see. It was not like ports 1-3 were fast and port 4 was slow. This is what we would expect.
UGREEN CM753 Power Consumption
The power adapter is a 12V 1A unit.
We hooked this up and saw a 1.0W result.
Adding a 2.5GbE connection pushed us to 1.3W.
This was the same as the other 5+1 switches we have seen previously.
Final Words
UGREEN is a brand that offers a range of accessories, including adapters, low-cost NICs, USB hubs, and more. There are some minor oddities here. An example is that the model number on the front is the UGREEN UM106X, but on the bottom label and on the PCB it is CM753. For these low-cost 2.5GbE switches, that is not a huge finding. Still, UGREEN has done some small things like adding the SFP+ internal heatsink and having the toggle switch. While those may seem like small touches, they might make this the best 5+1 switch we have tested.
Generally, we prefer the 4+2 switches over the 5+1 switches since they offer a bit more performance. If you just need five 2.5GbE ports, then this makes sense. So far, it has worked well, so perhaps this is going to take over our top 5+1 spot in our Ultimate Cheap Fanless 2.5GbE Switch Buyers Guide.
Where to Buy

In your Final Words, you don’t mention the metal chassis. That seems unusual in this price class (from what I’ve seen of your other reviews- I haven’t bought any of these dinky switches) and probably worth mentioning. I don’t care that it feels nicer, but the better heat dissipation is probably meaningful for at least some users.
Unless there’s some sort of reliability gotcha this seems like a value winner. if you want to convert SFP+s to copper you are looking at 25-$30/port for 2.5Gb or multi-gig modules, and those tend to be finnicky about cooling, so it’s fairly attractive if not desperately elegant to just uplink this puppy to one port instead. And, at this price/support bracket, the fact that there isn’t a management interface listening to the network is probably a virtue.
@justsomeguy: No, metal chassis are not at all unusual in these kind of cheap switches. On the contrary, the vast majority of them have one actually. This was true even for the one that sold for as little as $16 during the Black Friday sale recently as well as the ones that routinely sell for $25-30.
