Problem solved.  We had VLAN tagging on the SmartConnect and the ports on the switch wasn't configured for the VLAN we had tagged.  Thank you for your help.
Community,  Something weird happened today.  After adding nodes to the cluster none of the network connections worked.  We had the interfaces added to a SmartConnect Pool and everything yet the 1GB and 10GB interfaces where not getting pings.  The funny part is that the 1GB connection to the node worked before we added it to the cluster.  No we didn't test the connection to the 10GB beforehand but we did with the 1GB interface.  Have anyone experienced a similar issue?
