20. Power Interface
The coolMONSTER/PM is not a replacement for a power supply. It
is a +5V only boards. Additional voltages (+12V, -12V, and -5V
as well as +3.3V for external PCI-devices) are not generated
onboard. If peripheral devices require these voltages, they have
to be supplied through the backplane and the PISA bus.
In some applications, the COOLMONSTER-PM is intended for use as
a stand-alone module without a backplane. You need to have a
power connector available on the boards for direct power supply.
Power signals on the feature connector (X12) are not meant for
power supply purpose.
20.1 Connector
The power connector is available through connector X23 (5 pins)
and allows to supply +5V and +12V to the system. For ATX power
supply signals refer to additional information in the Feature
Connector section.

Notes: (

To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of
-- IEC/EN 60950.
The current of the pins on this connector is limited to 7A/pin.
The connector is from manufacturer MOLEX. To find the location
of the connector and get information about mating connector see
Appendix E: Connector Layout.

20.2 Configuration
The coolMONSTER/PM is equipped with a power management system.
You can configure lots of options for power-saving states such
as standby state with partial power reduction and suspend state
with full-power reduction. You can specify wake-up events that
bring the system back to full-on state. Please refer to the
Power menu section in the Appendix B: BIOS Operation chapter for
more information about power savings.
