    The compact model S6720S-26Q-EI-24S only has a depth of 220mm and can be installed in a 300mm deep cabinet, saving installation space.

  4. Roberto

    we bought Huawei QSFP-40G-CU5M stack cable with S6720 last month, now we need a longer distance cable, do you have 10m cable?

  5. Pedro

    Switch layer 3 and managed switch model with OSPF, BGP (ipv4/ipv6) function. The 48 10GE ports is enough, but we need more than two QSFP+ port, is there a solution?
