You should have got a message when you loaded the lanbase template that it loaded correctly. Try this, now that the sdm routing template is loaded initiate the express setup procedure again by holding the reset button until both red and green led’s blink alternately (about 15 seconds) then cycle power to the switch and press and hold the reset again to enter express setup once you power back up. I’ve found I’ve had to do this a couple of times when trying to reset the switch after a configuration is loaded. Make sure that you are actually in express setup again. Run through the routing configuration and see if it takes the gateway. If not spoof one and try that.
