Figure 7 Reset switch location
Some possible situations in which you use the reset feature are:
• If the BCM450 system is configured incorrectly to an extent that it is no longer functional. The
customer must use a level 1 reset to return to the default system programming and restore a
previous configuration or reconfigure the system.
• If distributors want to reuse BCM450 systems, they must first erase all customer-specific data
using a level 1 or level 2 reset.
Reset levels
Reset to factory settings is a stand-alone feature that has the following levels of reset:
• Level 1 reset erases all customer-specific data and restores the default configuration for all
components. This reset leaves the software components untouched. That is, the system has the
latest release and patch level of the software installed. Only the system and user configuration
data is erased and replaced with default values.
• Level 2 reset erases all customer and system configuration data and all software releases and
patches. This reset re-installs the original factory configuration settings.
Warning: If you perform a Level 2 reset to solve an undetermined problem and
still have access to Element Manager, you must retrieve all the log files for
technical support before performing the Level 2 reset. A Level 2 reset erases all
log files from the system.
