Problem With Port QSFP+ 40G to 4x10G

nahum — Thu, 27 Feb 2014 03:00:00 GMT

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.

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
