Mike thank you very much for the reply. Now I have the B4450 cards, I only have 40GB and 100GB ports so I want to make the failover connection through a 40GB port. I have the QSFP F5-UPG-QSFP + PSM4 on both cards, my question is what type of cable can I use to connect both cards to each other, from (F5-UPG-QSFP + PSM4) to (F5-UPG-QSFP + PSM4) , I am not sure what type of MTP / MPO patch cord I should use. Thanks

Hi Daniel,

 

You'll need a MPT/MPO-terminated OS2 8-fiber cable. Which, according to a fast search, is incredibly hard to find. I'm not sure if a 12-fiber cable would work.

 

I wonder why would one buy long range transceivers to connect things within a data center, but I guess now it's too late to change that :(
