3.5.5
Front Panel Switches (not on CP3923-RC)
The handle switch is actuated with the ejector handle of the board. It is used to signal the inserting 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 per-
forms a power cycle to all payload devices and resets the PM.
3.5.6
Backplane Connectors
The complete CompactPCI connector configuration comprises two connectors named J1 and J2.
The board supports signaling voltages V(I/O) of either 3.3 V or 5 V. No keying is required on J1 which designates universal
V(I/O).
For accessing the GbE interfaces signals without a rear I/O module, a backplane is required which routes the Ethernet sig-
nals directly to the CPU slots without the need of external cabling. Please contact Kontron if you're looking for such a solu-
tion.
