218 Reset to factory settings
• Level 3 reset leaves all data and software in tact. It provides a stand alone system with local
connectivity through a PC or serial dongle. There is no Ethernet connectivity to the system
during this operation. If the BCM50 is not reachable through the Ethernet port then the level 3
reset provides a stable system to start debugging.

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 following procedures:
• "Initiate a level 1 reset" on page 218
• "Initiate a level 2 reset" on page 218
• "Initiate a level 3 reset" on page 219
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
— Level 3 is green
• 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).
