N2K-B22DELL-P FEX Blade module support on N9K-C93180YC-FX on 10.5(1)

[vlk-vincent]

Hello Community,

please, is the N2K-B22DELL-P FEX Blade module supported on N9K-C93180YC-FX with NX-OS version 10.5(1)?

We see the FEX online, but all HIF ports on FEX are still in "notconnect" state. We tested this behavior on multiple FEX modules and Parent switches.

example:

According to FEX and N9K compatibility matrix, this modules should be supported:

Hello marce1000,

thank you for reply. We managed to get it working, so the N2K-B22DELL-P FEX Blade module *is* supported on N9K-C93180YC-FX with NX-OS version 10.5(1). After changing the IO module slots, the culprit was in physical connection of IO module in DELL Blade chassis.
