Read and note the warnings regarding defaulting the security settings before using this process.
•! Warning - Service Disruption
Whilst defaulting the security settings does not require a system reboot, it may cause service disruption for several minutes while the system generates a new default security certificate.
Use of the RS232 port should only be performed if absolutely necessary and only if the actions cannot be completed using IP Office Manager or IP Office Web Manager. In all cases, you must make every effort to ensure that you have a backup copy of the system configuration.
