I bought 2 pcs QSFP+ modules last week, used on my S6720-30C-EI-24S-AC switch, but when I connect it with patch cord, it doesn't work, I checked switch and QSFP+ are good, I really do not know where is the problem. :cry:

Before i encountered same problem with you. I though the QSFP+ itself does not work.

Later i consult offcial Huawei, they told me that the patch cord on 40G QSFP+ is different from the usually cord we use, need purchase separately.

Finally, I bought 40G qsfp patch cord locally, then my Huawei S6720-54C-EI-48S works well, and i think Huawei products goes more and more popular.
