Reset switch
Some possible situations in which you use the reset feature are:
= Tf the BCMSO 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 BCM50 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 | 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. No Ethernet connectivity to the system occurs
during this operation.
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. Level 2 reset also
resets the router firmware to what was shipped from the factory. No Ethernet connectivity to
the system occurs during this operation.
î Warning: If vou 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.
Activate the reset feature
You activate the reset feature by pressing the reset switch with a long, thin, nonmetallic needle in
the sequence described in the procedure To perform a Level | and Level 2 reset on page 166.
î Warning: Before performing a Level | or Level 2 reset, review all the effects of
the levels of reset. See Reset levels on page 165.
As you press the reset switch, the LEDs blink in a predefined fashion to guide and confirm user
input. The various states of the power and status LEDs indicate the following:
=
A blinking power LED indicates a user input window; the BCMS50 system is waiting for user
input.
A solid red power LED indicates extreme action is requested: caution is urged.
A solid status LED {any color) indicates level of reset action:
— Level | is yellow
— Level 2 is red
A blinking status LED indicates an interim state: trying to establish user request.
A solid status LED indicates confirmation of a user selection {power LED has priority).
To perform a Level 1 and Level 2 reset
The router configuration of a BCMS0a or BCMS0e is not affected by a Level | reset. To perform a
soft reset on the router, use Element Manager.
See the figure Level | and Level 2 reset sequence on page 167, or follow the sequence in the table
Level | reset on page 168 and the table Level 2 reset on page 168 to perform a Level | and Level 2
reset.
