ICX 7450-24 unable to use both 40g ports as uplink ports

[glydeon]

I have ICX 7450-24 updated to 09.0.10hT211 and I am unable to use both 40g ports at the same time to connect to two different TrueNAS servers.  It does not matter which cable I use on which 40g port I use.  First cable plugged in wins and that server is at 40g.  The second server plugged in works for a minute or two, then disconnects.  Am I able to use both 40 ports to connect to servers?  

As stated, the first server will work fine off of either 40g with any cable I use.

I purchased some Brocade / Ruckus 40g cables and will be testing with these shortly.

Well the new cables came in and both are working perfectly.  It still does not make sense to me why either one of the other cables would work, but only one at a time.  But I am satisfied that the issue was resolved.  Thanks for the help.  This one was self inflicted on my part.

Issue resolved.  This can be closed.  Thanks again for all of the help
