Front Panel Switches
•
The Handle Switch is actuated with the lower ejector handle of the board. It is used to signal the inserting or impend-
ing extraction of the board.
•
A reset switch is provided being activated with an adequate tool (e.g. pencil). When the switch is pressed, the board
performs a power cycle to all payload devices and resets the PM.

Jumpers
The CP6930-1 provides one jumper for board configuration. When the Flash Write Protection Disable (FWPD) jumper is set,
the bootloader code in the flash is unprotected. When it is removed (default setting), writing to the bootloader sectors is
not possible.
The FWPD jumper is to be set on header J11, pins 9-11. All other pins shall not be used.
