Nexus - 5010 and 2232 - FEX doesn't come up

Hi

Just received hardware I am prepping. I got vPC peerlink up and uplinked to VSS. We configured straight-through FEX and it is not connecting.

Below is the output of the show fex detail command:

I am thinking software incompatability.

Any ideas on how to resolve this.

Urgent help

Many thanks,

Mohammed

Re: Nexus - 5010 and 2232 - FEX doesn't come up

Your Nexus 5000 image version (4.1.3) needs to be upgraded to a 4.2 version so the 2232 can work with it.

Nexus - 5010 and 2232 - FEX doesn't come up

FEX: 100 Description: FEX0100   state: Image Download

When you connect your FEX, it first downloads the image from the parent switch (like a LAP from a WLC), then it reboots. Is it stuck in this phase for a long time?
