  • 1.  Problem With Port QSFP+ 40G to 4x10G

    Posted 02-26-2014 19:00
    hello

    I have the following situation:

    I have a Switch summit x670. I have configured 2-port QSFP + as 4x10G each, in which I am connecting a cable with MPO connector to 6 lc connectors.
    The problem is that when I connect the cable, I have no link nor in the QSFP + port, nor in SFP + ports.
    I have configured the ports to 10000 speed, full duplex, auto off. I have also assigned four vlans tag and untag one in each port 10g.
    I appreciate the support.
    Sorry for my bad English.
    regards

    Hi Nahum,

    I assume that you have a SummitX-670V with a 40 gig VIM module.
    I don't know your exact cable assembly but we only support a QSFP+ break-out cable with 4 lc connectors.

    Please clarify your environment.

    Thanks

    Ron

    hi Ron

    My cable is 6 lc connectors. I suppose that's the problem. You think I can run with this cable?

    Because already purchased.

    Thanks for the answer.

    regards

    Hi Nahum,

    Unfortunately it is not possible to use this type of cable. The QSFP in 4 x 10gig mode will only support a breakout cable with 4 lc connectors.

    Thanks,
    Ron

    Hi Nahum,

    I think that is the right cable. It does look similar to the one I have.
    All connectors seems the right type as well as the fiber type.

    For proper clarification, you can contact your local SE.

    Thanks,

    Ron
