The following are things you need to consider before pairing the NSX Manager with the vCenter server:
- Solution interoperability has been verified
- vCenter server and vSphere environment are in a healthy state
- Platform Services Controller (PSC) Fully Qualified Domain Name (FQDN) can be resolved
- vCenter server FQDN can be resolved
- vCenter and PSC time settings are verified
- A service account with administrator role in vCenter has been created for the NSX Manager to use for registration; for further information refer to Chapter 9, Managing User Accounts in VMware NSX
- TCP port 443 connectivity is required from the NSX Manager to the platform services controller and the vCenter server
