If you have been designated the Technical Contact for your site by the Principal Investigator, register for a PlanetLab account. Answer Yes in response to the question Are you a Technical Contact?.

If you are the PI for your site and wish to administer your nodes yourself, you should have already registered for an account. If you have not done so already, please read the Principal Investigator's Guide before continuing.

After registering, ask your PI to enable your account. After your account has been enabled, you may login to the website and update certain details about your site, including its physical location (latitude and longitude coordinates) and the subnet(s) on which your nodes reside. You can also manage the nodes at your site, including adding new nodes and managing existing ones.
