You would need a router or Layer 3 switch to route between the VLANs. There are several Dell switches that can perform VLAN routing, but the N2048 is layer 2. What other networking devices do you have on the network? You may find that you already have something that can perform the routing.
 New to Dell switches, can someone advise or point me to a link on how to create a VLAN? I need to separate our current network into 2 separate subnets.  Thanks in advance.
