3.5.3 Front Panel Switches

• The Handle Switch is actuated with the lower ejector handle of the board. It is used to signal the insert-

ing or impending 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.

The CP6930 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.

For normal operation, the jumper is not required. Modifying or delet-

ing the bootloader can leave the board inoperable.

The FWPD jumper is to be set on header J11, pins 9-11. All other pins shall not be used.

The complete CompactPCI connector configuration comprises five connectors named J1 to J5. Their func-

tions are as follows:

• J1, J2: management, IPMB and power, PCI is not supported

• J3, J4 and J5 have rear I/O interface functionality, providing GbE to the backplane or RIO module and

an RS232 interface to a RIO module

The board supports signaling voltages V(I/O) of either 3.3 V or 5 V. No keying is required on J1 which desig-

nates universal V(I/O).

For accessing the GbE interfaces signals on connectors J3, J4 and J5 with a rear I/O module, a special back-

plane is necessary. The CP6930 is compatible with all standard 6U CompactPCI passive backplanes with rear

I/O support on the system slot.
