3.17 Power and Fan Connectors

The CPBH provides one 4-pin and one 20-pin ATX power connectors at CN1 and CN5.

The CPBH must use P4 power supply. One of 4-pin connectors is for +12V lead which should be connected to CN1.

A 20-pin ATX Power Connector can be connected to Backplane or to CN5. If a 20-pin ATX Power Connector connects to Backplane, please make sure CN23 and Backplane’s 5-pin ATX controller is connected together!

IMPORTANT: Please plug CN1 (4-pin ATX power connector) before CN5 (20-pin ATX power connector) for protecting hardware circuit.
