Looks like your SC vswitch (vswitch0) has a uplink to vmnic0 which shows as up. Looks like your original 2 NIC's were moved to vmnic2 and vmnic3. Try setting a static address as suggested using the command esxcfg-vswif -i <ip address> -n <subnet mask>

If you right click the host do you get the connect option? Can you ping it from the VC?

If so and you do not have the connect option you could remove it fronm the cluster and then re-add it.

You would right click the host and select remove. If this does not work or
is not available there are other things to do to remove it. Give this a try
and see what option you have. To re add it you would right click the cluster
and select add host and go through the wizard.
