Okay, thanks for providing that Ian. I'm trying to think through what might cause this case and how we might better handle this. I'm reviewing the PRM but will probably need some time on this one. One question I have is on this particular box are those on-board ports shared with the BMC? And are you using the dedicated BMC ports? I'm just wondering if, like the issue Dale mentioned with the X550, because we have a shared management port, the link was up and we never really reset it properly in the driver to run at full speed vs. it having been programmed for other, more limited speeds by the BMC.
