Since you are new to CLI I would suggest using CCA to configure the UC500. It is pretty straightforward and you could go back after and review what it did in the CLI. If you would prefer to do CLI you could post your running config and the errors related to ISE0/0 would be helpful.
can you get console access on UC500? What does it look like? If still asking for initial configuration dialog I would say no. Then you may have to type enable and show run will get you the running config. Sounds like if you are not getting DHCP from the UC500 then the base config is no available. Once you get an IP on an interface you should be able to use CCA.
