When you have completed the Oracle Configuration Wizard, log in to the Fabric Interconnect, and change the root password:
login as: root Password: root
# passwd Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully #
# logout
There is no further need for the direct serial port connection. You can continue with the system configuration using the direct connection if you wish. Or, you can close the connection and complete the system configuration remotely, over a network using SSH.
