Hello,

I have 8 M630 blade servers with
- Intel(R) 10GbE 2P X710-k bNDC (Fabric A
- BRCM 10GbE 2P 57810S-k Mezz (Fabric C)

A1: M6348 switch
C1: M6348 switch

For C1 (4 lanes), everything just fine.
But for A1 (2 lanes), not all links usable.
ONLY 1,4, 5, 8, 11-14 are usable like this

So I cannot use slot 1-8 for fabric A

I try to swap, M6348 switch between A1 and C1. got same result.

Please suggest me, what I missing
