I have an HP 5406zl switch running the latest firmware in the non-early release branch (K.15.14.0007, ROM K.15.30) and it is not accepting direct attach SFP+ cables in its SFP+ module. The module is a
J9538A 8x 10GbE SFP+ module. The direct attach cables are Mellanox brand passive copper cables.

I would love to be able to get this switch working without having to shell out for HP direct attach cables at 4-5 times the price.
