all side band signals TTL level compliant, +3.45V maximum input voltage
The P5 V
OUT
power pins are provided to supply active components on an optional rear I/O module, e.g.
RS-232 transceivers. These pins are not connected by default, but can be configured as described
below on customers request:
V
OUT
+12V is not available by default. On customers request, the V
OUT
+12V pins can be connected
either to the CPU carrier board voltage +12V_A, or to the P1 backplane connector power pins +12V,
fused via a pair of resettable PTCs, 0.5A each (1A in total) nominal hold current. Please note that the
CPU voltage +12V_A may not be available, dependent on the CPU carrier card and optional presence
of a +12V power supply in CPCI classic systems. In order to be used as +12V source, the P1
connector power pins would require a suitable power supply connected to P1, e.g. via a secondary
CPCI Serial backplane.
V
OUT
+5V is not available by default. On customers request, the V
OUT
+5V pins can be connected to
the CPU carrier board voltage +5V_CR, via a pair of resettable PTC fuses, 1.5A each (3A in total)
nominal hold current. This voltage is controlled by the CPU card according to the current sleep state.
