Sql Access to individual node in a cluster

I setup my first Sql 2014 cluster. (Windows 2012 R2, Sql 2014). I can successfully use Management Studio by pointing it to  the Sql Cluster name but not when I point to the Sql server instance on a individual node in the cluster.  I get "server could not be found". On the one hand this makes sense ("hands off the nodes"; stick with the published name) but how then can sql maintenance be done directly on a particular node?

TIA,

P.S The cluster uses shared storage. (SMB 3.0 file shares)
