SSH from the client to the server

Run the following command from a workstation with an SSH client, assuming that the private key file is called id_rsa and resides in directory $KEY_PATH:
ssh -i $KEY_PATH/id_rsa -p 8022 admin@zcx_hostname
This was tested with OpenSSH_7.5p1 on Ubuntu Linux and OpenSSH_7.9p1 on Mac.

SSH using PuTTY
