This connector accepts one standard ATX power supply.
The 30-pin connector CN1 is an interface for an optional external
monitoring and alarm module which monitors the conditions of the
system. This alarm module will be available in August 2001. For more
information about it , please contact with our local sales representives
or visit our website.
This connector provides power on/off control of the ATX power
supply or the plug-in power module. If the CompactPCI
provides a 2-pin power switch cord, connect this cord to the JP1
connector and users can control the power on/off by the power
switch. Or users can directly short this connector by a jumper and
control the power on/off by the ATX power supply switch.
This jumper is used to select the V I/O voltage. The backplane allows
V I/O to be set to either 5 V or 3.3 V. Since the default is configured for
use with 5 V CompactPCI boards (blue keyed connectors), once the
jumper is set to 3.3 V, the CompactPCI keys must be changed to 3.3 V
at the same time (as yellow keyed connectors).
