QSW-2104-2S-A-US: 2.5GbE RJ45 & 10G SFP+ Plug & Play Network Switch

Put this switch in place to bring 2.5gbps ports to my core switch without wasting 10gbps SFP+ ports on my more expensive switch. Works great. Haven't tried an LACP link with the 10gbps ports because I am pretty sure this switch doesn't support it. Not a huge problem... if I ever need it I'd buy a second of this switch and set up NIC teaming/failover on my client systems.

To start, I'll say I'm just glad it works as advertised. I tried a Zyxel XGS1250-12 and a cheap knockoff no-name brand from Amazon. There's no frills with this switch, just plug and play. I get full bandwidth over the SFP+ from my router (Asus RT-AX89X) with my PC connected to one of the 4 2.5gbps ports. This is only day 1 but I'm just pleased that it works. This switch handles ALL my internet traffic except the wifi from the main router. My node/access point wifi units are plugged into this switch to eliminate any unnecessary switching duties from my router (the only cable plugged into my main router is the SFP+) . I will update this review if anything changes.

I've been using this low wattage switch for over a year and it just works. No issues at all with the SFP+ sockets.

Pretty good so far. Plug and play, uses 4w on my powermeter (2x10gbps, 2x1gpbs), produces no noise because no fan and (the exterior) never got warm enough for me to think it was overheating, would stay below body temperature. Only had one issue: one of my computers (connect-x3) hung and the switch was power cycling forever while that computer was still hung and connected. This has only happened once and I don't know which started the issue, but the switch wouldn't stop resetting while the computer was in the broken state (which affected other machines). Resetting the computer fixed it and haven't replicated the issue. In a home environment this isn't an issue, but might consider this if you have remote computers you needed to manage.

This worked great to bridge my NAS and Router to my modem. Affordable and there’s a variety of styles. I have SPF so that’s what I chose but they have RJ45 Copper versions as well. If you don’t need to trunk/aggregate anything this is a stable solution. Has been up and running for over a month now.👍

If you have a 10 Gb/s backbone for your local network, this device works very well as a fiber converter with devices that are only 2.5 Gb/s or slower. Very quiet and it has not gotten hot. Been using it a couple of months and there have been no problems.

Solid cheap unmanaged switch 10G uplink with a spare sfp+ port for whatever your needs are with four 2.5G rj45 jacks that can all get full speed from the uplink at once The included USA power supply is UL listed Works great with ubiquiti UniFi 10G multi mode 300M fiber sfp+ modules and they max out around 41C on my unit My fiber cable is a cablematters lc to lc OM3 30 foot multi mode cable if it helps

Worked fine for about a year. Now it throws loop errors and constantly reboots. I have 2 of them daisy chained from a QNAP managed switch (managed one works fine). Devices that throw loop error are Samsung TVs, Dell dock with no laptop attached and 2 multi adapters i use as DeX dock for Samsung phones without phones attached. Whwn a loop is detected it constantly reboots and soes jot stop rebooting until those devices are disconnected. I bought other brand switches to replace these, NEVER buying QNAP unmanged again.

good value of money for 10Gb SPF+ network, connectivity is good, and speed is good.

Used a DAC to attach it to my UDM PRO and it worked immediately out of the box .

working perfect , took time for ship but ok

worked flawlessly and is quiet

Good. As Described!
