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 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

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 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.
