Is FET-40G transceiver supported in FI-64108?

[Markus5849]

I've checked the FI 64108/6400 spec sheet but I can't see FET-40G transceiver on the list of supported transceiver. I can see other 40G QSfP but not FET-40G. May I know if this FET-40G is supported on FI 64108?

Compatible/supported SFP can be found here:

It does not look like the FET-40G is supported.

In that case, can I use break out cable to connect my FI with the IO module? I have hardware as below:

Fabric interconnect: FI-64108

IO Module: UCS-IOM-2304V2

Think of using MPO cable break out to 4x10G LC and connect to fabric interconnect, will this work?

The 2304 is not supported with the 6400. You would want to get a 2204 or 2208 for 10G connectivity or 2408 for 25G connectivity to your 64108.
