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.

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.

C onfiguration
8 8 B
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.
