1. Go to Administration > Settings > Apex Central.
2. Specify the entity display name, which is the name of the Apex One server that will display in Apex Central.

   By default, entity display name includes the server computer's host name and this product's name (for example, Server01_OSCE).

   Note:

   In Apex Central, Apex One servers and other products managed by Apex Central are referred to as "entities".

3. Specify the Apex Central server FQDN or IP address and the port number to use to connect to this server. Optionally connect with increased security using HTTPS.

   • For a dual-stack Apex One server, type the Apex Central FQDN or IP address (IPv4 or IPv6, if available).

   • For a pure IPv4 Apex One server, type the Apex Central FQDN or IPv4 address.

   • For a pure IPv6 Apex One server, type the Apex Central FQDN or IPv6 address.

4. Beside Apex Central certificate, click Browse... and select the certificate file downloaded from the target Apex Central server.

   To obtain the Apex Central certificate file, go to the Apex Central server and copy the certificate file to the Apex One server from the following location:

   <Apex Central installation folder>\Certificate\CA\TMCM_CA_Cert.pem

   Important:

   If your company uses a customized certificate on the Apex Central server, you must upload the Root CA certificate during the Apex Central registration.

   For more information, see Apex Central Certificate Authorization.

5. If the IIS web server of Apex Central requires authentication, type the user name and password.
6. If you will use a proxy server to connect to the Apex Central server, specify the following proxy settings:

   • Proxy protocol

   • Server FQDN or IPv4/IPv6 address and port

   • Proxy server authentication user ID and password

7. Decide whether to use one-way communication or two-way communication port forwarding, and then specify the IPv4/IPv6 address and port.
8. To check whether Apex One can connect to the Apex Central server based on the settings you specified, click Test Connection.

   Click Register if a connection was successfully established.

9. If the Control Manager server is version 6.0 SP1 or later or you use the Apex Central server, a message appears prompting you to use the Apex Central server as the update source for the Apex One integrated Smart Protection Server. Click OK to use the Apex Central server as the integrated Smart Protection Server update source or Cancel to continue using the current update source (by default, the ActiveUpdate server).
10. If you change any of the settings on this screen after registration, click Update Settings after changing the settings to notify the Apex Central server of the changes.
    Note:

    If the Apex Central server is connected to a Virtual Analyzer, the automatic subscription process starts after the registration is complete. For more information, see Suspicious Object List Settings.

11. If you no longer want the Apex Central server to manage Apex One, click Unregister.
