![IVANKY VESA Certified DisplayPort Cable, 6.6ft DP Cable 1.2,[4K@60Hz, 2K@165Hz, 2K@144Hz], Gold-Plated Braided High Speed Dis](https://images-na.ssl-images-amazon.com/images/I/71w-nKtHOcL._AC_UL116_SR116,116_.jpg)
I've been slowly upgrading my home network to be 2.5G capable (at minimum) for a couple years. I also upgraded my two main workstations with 10G cards (one using SFP+, the other RJ45).
This switch's simplicity and decent low cost attracted me to it, after having some weird configuration issues with a MikroTik router. The setup was easier, the UI of their web management interface is simpler (if just using as a switch—note that this is _not_ a router!).
And more importantly, since this switch is designed for both 2.5G (8 ports) and 10G (2 combo ports), it's nice to be able to glance at it and see if a device is linked at 2.5 or 1G just by the LED that's lit (the MikroTik router would just show 'green' for connection, and didn't indicate link speed).
This is how I discovered that 2.5G network adapters on macOS actually work at 2.5G even if the Network system preference pane shows it as '1000baseT'!
Anyways, I've had this running a week or so and it's been quiet (but not silent), efficient, and I see no packet loss or unexplained bandwidth issues beyond 1 Gbps like I sometimes did with the MikroTik.
Great option if you don't want to spend the chunk of money that is required to upgrade everything to 10G.

QNAP QSW 2108-2C is a 10Gb & 2.5Gb Solid Performer. - Update 4-12-2021
QNAP QSW 2108-2C = 10Gb & 2.5Gb Solid Performer. Perfect to SBHO Hi Speed Network Conversion & Expansion.QNAP excellent Hi-Speed Network Switch, QSW-M2108-2C. This auto detect 5 Speed 10Gb Switch (2 combo ports) & 8 x 2.5Gb ports is just perfect. The 2.5 Gb ports also are auto-detect & each port easily switches down to 1Gb.In the 10Gb Combo ports, I use a duplex fiber connection with a 10Gb Transceiver in the SFP+ port and a Cat8 cable in the other RJ-45 port.I've tested the autodetect 10Gb ports at 10GB & 1Gb speeds via fiber network sources & also 10Gb, 5Gb, 2.5Gb & 1Gb speed network sources in the RJ-45 ports. All autodetected, auto-switched & worked perfectly as expected.In the 8 x 2.5Gb ports I have Cat7, Cat6 & Cat5e network sources (2.5Gb & 1Gb network speed sources). And FYI, a 5Gb or 10Gb network speed cable source when connected to the 2.5GB port auto locks-in at 2.5Gb. All lock-in & operate at 2.5Gb except 1Gb locks-in as 1Gb as expected.The QNAP Qfinder Pro software is excellent also, that I use for my QNAP TS-253D NAS. Qfinder Pro also finds and connects to my QSW-M2108-2C over my network. The Managed Switch QNAP QSS graphic user interface is very intuitive and boots right up from inside Qfinder Pro.The QSS GUI shows all active/inactive ports, each 2.5 & 10Gb port connected speeds, each port real time traffic and much more. Each port can be enabled & disabled from QSS GUI. Link aggregation is accomplished within QSS GUI, too.Also, I'm connecting a couple of QNAP's 2.5Gb 5 Port Un-managed switches (QSW-1105-5T) to the M2108 ports. All ports show 2.5Gb lock-in green lights, QSS indicates 2.5Gb speeds and work perfectly.The QNAP USB Ethernet Adapter QNA-UC5G1T from multiple PC's connects at a solid 5Gb to QNAP & my MicroTik 10Gb port. Also, Pluggable & Trendnet 2.5Gb ethernet adapters work great with this QNAP Hi Speed QSW M2018-2C switch hardware.All of these Ethernet adapters are affordable to get the sources network signal up to 2.5 & 5Gb speeds from your PC's (vis USB 3 or USB C Ports) & 5Gb from your QNAP NAS USB 3 Ports, too It truly is plug & Play.Will configure Link Aggregation using my ethernet Linksys Router Software & M2108 managed switch QSS software soon.Also, QNAP 10Gb PCIe NIC's (QNAP QXG-10G1T) in a QNAP NAS & desktop PC. Its all a Flawless operation.The QSW M2108-2C is the perfect core managed switch for a small 10Gb, 5Gb & 2.5Gb Hi-speed network (SBHO).UPDATE 4-12-2021:Recently I set-up Link Aggregation (2 ea - 1Gb Ports In Static Mode thus a 2Gb wide lane) from my Linksys EA8300 WiFi Router to the QSW-M2108 as LAG1 (2ea - 2.5Gb ports). Also, set-up Link Aggregation (aka Port Trunking) from the QSW-M2108 (2ea - 2.5Gb ports in LACP Mode thus a 5Gb wide Lane) as LAG2 to a QNAP TS-253D NAS (using both 2.5Gb ports thus a 5Gb wide lane). All are working fine and were easy to set-up. PC's with USB 5 & 2.5Gb Adapters are still connected in the other 2.5Gb M2108 Ports.Also, one of the QSW M2108 10Gb combo RJ-45 ports connects to a 10Gb PCIe upgrade NIC in the TS-253D.More solid wins for the M2108 Layer2 Switch "workhorse". All done with existing Cat6 cable. +++

I don't have any 10Gbps or any SPF+ deviced, so for the moment I only use it as a 10 ports 2.5Gbps switch.
Installation is straight forward like others if you don't need any of the management functions. You don't even need to use the web control interface if all you need is a plug and play switch.
The LED status light shows orange for none multi Gbits connection and green for 2.5Gbps or above. This is handy for check the network speed at a glance. Not all network devices do so. Some doesn't even have LED status at all.
For my 2.5Gbps network, this one so far works well. Why I only give it a four star?
There are a few minor points and one big problem to me.
Although in today's market, this is by no means the most expensive multi G switch, it is not cheap either.
The engineer made a very strange choice in terms power connector. Instead of the standard coaxial type to the back of the switch, they choose to mold a green plastic around and plug in to top of the unit. This made it difficult to replace should the cable got broken. Similarly, the cable between the wall power outlet and transformer brick is not the standard IEC 320 socket to the brick. I think these design were done on purpose to lock in to customer to buy replacement from them. This practice alone deserve one star deduction.
Although Amazon's product description indicates this switch has a fan, the label on the box says it is fanless! Clearly the original design called for fanless and the box label was designed accordingly. Later, when the temperature profile require to a fan, no one tells the label designer. When they are ready to ship the product, they are either too lazy to check and verify all the details or too cheap to redo and reprint the label. Mind you the package box is a generic brown box with a product label slap on it. Even they have redo the entire box, they should have done so, let alone just a label. As is the box label is inconsistent with the product and they deserve one star deduction.
For the price of the product, one would expect they would at least put in a quite one. But no! They seems bent on saving cost on a noisy one. I measure 52db at the vent. To make matter worse, the fan is not temperature controlled but constantly on. This is one and only switch I got has fan and it is noiser than my PC's CPU cooling fan. Depends on your tolerance to noise and the location of the switch, this may or may not bother you. To me, another star.
While I should give this switch only a two stars rating, in view of the first two grievances do not affect daily operation, I rate it as three stars.
