Problem With Port QSFP+ 40G to 4x10G

[nahum]

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
