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. It leaves the software components untouched. That is, the system has the latest
release and patch level of the software installed on the system. Only the system and user
configuration data is erased and replaced with default values. There is no Ethernet
connectivity to the system during this operation.
• Level 2 reset erases all customer and system configuration data and all software releases and
patches. It re-installs the configuration that the system had when it was shipped from factory.
Level 2 reset also resets the router firmware to what was shipped from the factory. There is no
Ethernet connectivity to the system during this operation.
Activate the reset feature
You activate the reset feature by pressing the reset switch with a long, thin, non-metallic needle in
the sequence described in the procedure
“To perform a Level 1 and Level 2 reset” .
As you press the reset switch, the LEDs blink in a pre-defined 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 BCM50 system is waiting for
user input.
• A solid red power LED indicates “extreme action has been requested – caution urged”.
• A solid status LED (any color) indicates level of reset action:
— Level 1 is yellow
— Level 2 is red
• A blinking status LED indicates “interim state – trying to establish user request”.
• A solid status LED indicates confirmation of user selection (power LED has priority).
To perform a Level 1 and Level 2 reset
The router configuration of a BCM50a or BCM50e is not affected by a Level 1 reset. To reset the
router configuration, use Element Manager to perform a soft reset on the router.
Refer to Figure 62 on page 165 or follow the sequence in Table 32 on page 166 and Table 33 on
page 166 to perform a Level 1 and Level 2 reset.
Caution: Only use this feature in situations where all customer-specific data
must be erased.
