Objective
In situations where the administrator password is lost or forgotten, the password recovery procedure can be used to reset any of the user access or privileged passwords on the device. This article describes how to reset passwords on the UC500 series.
Note: Since this procedure reboots the device, any changes made to the configuration since the last time the configuration was saved are lost.
