Hello Bob:

On the X300/X310, when using the HGS image, Port 0 must be connected to 1
GbE, and Port 1 must be connected to 10 GbE. Are you saying that you are
able to use 1 GbE on Port 0, but 10 GbE on Port 1 doesn't work? There is
some documentation about this at the link below.


Please let me know about the firewall as well, although I don't think this
is the cause of the problem.
