Re: Error on node creation

Did you follow all the steps in the quick start, including configuring your PC's static IP address? After the boards boot does your switch show stable 1Gb links? Can you ping the nodes from the PC? Node is 0 will have IP address 10.0.0.1, node 1 with have address 10.0.0.2.
