Enabling/Configuring STP on PowerConnect 2848

Hello all, 
I have purchased 4  2848 switches and I logged into them to configure the STP so they all play nice together. It would seem that STP is enabled by default and is enabled on every port already. Is this accurate? Do I need to manually assign 2 ports on each switch for the links or is this basically plug and play. That seems a little to good to be true so I thought I would ask the community. Thank you for all your help.
