If you order any vSphere license (Essentials Plus, Standard, Enterprise,
Enterprise Plus, Virtual SAN, or vCenter Server) with your server,
the license
certificate is shipped on a media with the server. To use the software and receive
the subscription services, register, and exchange the Partner Activation
Code (PAC) printed on the license certificate for a license key or
license activation code. The registration must be completed within
30 days from the date of product purchase. With registration of the
licensing or use of the ESXi hypervisor, you are agreeing to the VMware
ESXi and/or VMware vCenter Server End User License Agreement (EULA)
posted at Vmware.com/download/eula/.
