VMware HCX Activation and Initial Configuration

First deploy HCX as a VM and after that activate the HCX Manager.

Prerequisites

The HCX OVA deployment must complete fully before you begin. Allow up to five minutes after the HCX OVA deployment for the services to initialize.

Browse to the HCX appliance management interface and authenticate using the admin user.
Browse to https://hcx-ip-or-fqdn:9443, in my case it’s 172.16.10.166

3. After login you will see this screen click on Continue.

4. Here you have to enter key.

5. After entering HCX key click on Activation.

6. (Optional) If there is a proxy server in the environment in the path for outbound HTTPS connections, click Configure Proxy (Optional).

7. If a proxy server is entered, add the local vCenter, ESXi, NSX, SSO, and HCX-IX systems as exceptions not to be sent to the proxy server.

8. Click Activate.
