    Problems after several years of use.

    I was initially very happy with this switch, it's quiet, doesn't heat up and supports the advertised data rate well.
    But after just over two years, I'm starting to have problems, all the ports lock up seemingly at random once every week or two, and you have to unplug and plug them back in to get things working again.
    I can't work out whether a piece of equipment on my network is causing the problem, I've got some old 10gbps intel x540T2 cards, but I've got the impression that the switch sometimes crashes even when these machines are switched off. In any case, the network loop detection light isn't active when this happens, so I doubt it's one of the switch's safety features that's triggered.

    Very good 2.5/10G Ethernet switch

    Works without a hitch, allowing me to connect my box and my nas in 10G, and my PCs in 2.5G. It makes a big difference to life compared with gigabit Ethernet (1G). I can wholeheartedly recommend this Qnap switch!

    QNAP QSW-2104-2T

    This switch synchronises perfectly at the expected speeds (10, 2.5, 1 gb) with the coloured LEDs showing the connection quality.
    At 2.5 gb, copies are made at more than 300 MB/s, making ISCSI disk backups really usable.
    Even with cat 6A S/FTP cable.
    The power consumption is 4.5v idle, for a 1 Gb port it is 0.2v, for a 2.5 Gb port it is 0.7v, and for a 10 Gb port it is 1.2v
    It's a pity that it's not manageable, with for example a vLan management.
    Very stable even in hot weather.
    To be recommended, if you really want to saturate your fibre speed...

    Perfect!

    Nothing to say that it is perfect!
    Performance at the rendezvous, stability even if it is 40 degrees the product does not show the slightest degradation in performance!
    I recommend it!

    Done on Job

    No worries with this totally autonomous switch. Green lights if you are connected to the maximum of the port's possibilities, orange lights otherwise. Simple and efficient. Heats up quite a bit, but as it's passive it's inevitable.

    Super

    Great tools, very efficient. A flow of more than 2go. Lightweight and can be hung on the wall. Great quality. I recommend it.

    QNAP Switch QSW-2104-2T

    Quality switch that immediately recognizes the speed with the connected device, lighted green when connected to a 10G or 2.5G device with an RJ45 Cat 7/ S/FTP cord or orange when the connected device is below its values.
