    WTB ICX7250-24 + 4 x 10GBase-T SFP+ Transceivers

    Brocade ICX-6450--C12-PD Cant get the SFP+ ports to work

    The "F1" and "F2" ports will take an SFP+ transceivers, and in fact the unit came with two 1GBASE-LR transceivers. Judging by the temp of a 10GBase-T transceiver they are receiving power, however neither of the transceivers seem to be recognized by the switch. I have another ICX-6450-24P that...

    Chelsio nic goes down after ~5 minutes

    Hi, I got two used Chelsio 110-1160-50 T520-CR nics off ebay. One of them seems to work fine. The other works as expected, but after about 5 - 10 minutes, suddenly goes down. That is to say, in Freenas it reports as “down” in the interfaces menu, and in Windows it shows “Network cable...

    Making a 10G SFP+ switch Nbase-T capable?

As I need Nbase-T capabilities and most of the 10G SFP+ switches I'm currently watching...

    [Sold-out] G8264CS switch (48xSFP+ and 4xQSFP+) - $130.00 free shipping

    Basically I know nothing about this product. It seems to be nice only because of the ports for this price. There were few posts talking about similar model: G8264 of IBM, such as this thread.
