Adding a node to the cluster

To add a node to the cluster:

1. In the application web interface window, select the Nodes section.
2. Click Add node.

   This opens the Add node window.

3. In the IP address and Port fields, type the IP address and port of the server hosting the application that you want to add as a cluster node.
4. If necessary, type additional information about the node you are adding in the Comment field.
5. In the Scan threads field, enter the number of traffic streams that the mail server can process simultaneously.

   Default value: 16.

6. Click Next.
7. Compare the certificate fingerprint in the Check node window with the certificate fingerprint of the server. If the certificate fingerprints match, click Confirm.

   The certificate fingerprint is displayed in the local console of the server after the Initial Configuration Wizard completes.

The node is added to the cluster and is displayed in the node table on the Nodes page.

To use the time zone configured for the other nodes, restart the new cluster node.

Before you direct email traffic to the added node, you must update application databases and perform LDAP synchronization. Otherwise, the application cannot provide an adequate level of protection or place email messages in Personal Backup, and rules that mention attributes of Active Directory accounts cannot be applied.
