I'm not sure what you mean when you say you closed the system down. If you stopped the HeadNode, in the EC2 console, you can just start it again. However, this wouldn't work if you terminated the instance, or deleted the Cloudformation stack.
What you are looking for would be
pcluster ssh --cluster <>...The headnode shuts down and may need to be restarted again withaws ec2 start-instances --instance-ids <>
