Max members on FEX exceeded Error Help

[Hogan.BrendanT1]

I have an issue with my FEX that I hope someone can help with.

I created a channel group and then went in to assign ports to the channel group on the FEX.  I was able to put one interface in the channel group but when adding the next one I got this error:

Command failed: port not compatible [Max members on FEX exceeded ]

I only have 10 ports active on the FEX and only 1 channel group (the one I created) on it as well.  So why is it that this error is popping up?

Thanks in advance.

What is the parent switch you are connecting to?

How many FEXs are already connected to the parent switche?

Parent is 2 dual homed 5548s, have 6 FEXs attached to them but very few channel groups and interfaces assigned to them. Both of these are configured exactly the same.

4x2148 FEX (2 of them are the 2 I'm configuring and have the error with above)

2x2248 FEX
