PowerConnect 3524 VLAN help.

I have inherited the administration of a PowerConnect 3524P. We had to reset it to factory as the prior admin left no credentials. I have never used Dell switches before (used to Netgear or Ubiquiti for Layer 2). I am pulling my hair out trying to accomplish what I think is a fairly simple configuration.

1. Use the G3 port to uplink to our router. So far I get nothing unless the router is connected to any of the ports 1-24

2. Setup ports 1-14 to serve up VLAN 20 from my router. I have set the ports up to be members of VLAN 20 and have it set to tag, but I get nothing. Again, I'm used to configuring this on other brands and I'm sure I'm just overlooking something simple.

Any assistance would be much appreciated. 

thanks!
