A trusted certificate must be a Certificate Authority (CA) certificate. To add a trusted certificate to certificate repository, upload the pem format file to /var/home/ftp/pub directory. Trusted certificate installation must be performed on the active Communication Manager server in a Duplex system pair.
Note:
There is NO need to copy the root CA cert file to the standby Communication Manager server. The root CA cert file is copied by Communication Manager’s active server, as part of server synchronization, immediately after the CA cert was installed onto the active Communication Manager server.
