## Description

QNAP Ethernet Switch, 4 Ports, 2.5 Gigabit Ethernet, 10 Gigabit Ethernet, 2.5GBase-T, 2 Layer Supported, Twisted Pair

Review: Solid basic 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.
Review: After using other brands, this one WORKS - 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 desertcart. 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.
