Connecting between Dell switches

Question

Dear all,

I have this problem: I am trying ot create a connection between 2 Dell S4112T-ON switches and on the opposite side I have 4 stacked Dell N1148T-ON switches.

The cables are 40G QSFP+ to 4x10G SPF+ made by FS ( www.fs.com ). The S4112T are connected via port 15 (QSPF28) port and the opposite side is via port 27 (10Gb) port on the N1148T-ON. For some reason non of the switches sides can't "see" the connection between and can"t recognize the optic fiber cable.

The engineers from FS told me that: The port on S4112T is 100Gb and maybe it"s not supporting the 40Gb QSFP+ cable that we are trying to use.

Any advices?

Thank You

Hi MartinVidas, How long is the cable? Is it a passive or active cable? We have 40->4X10 breakout cables.

Hi Josh,

see the answer, that I've got from FS:

"After checking with our engineers, Dell N1148T-ON switch only has 10G ports while Dell S4112T-ON switch has 100G ports.

The two switches couldn't be connected via DAC & AOC."

In this case I don't know if breakout cable will work (I have and checked - it is not recognized in the switch itself).

We tried to connect it with 10m fiber-optic cable.

Thank You
