Note 1:
You cannot use both 20-pin power connectors located at JWR1 (the
right side connector) and JWR2 (the left side connector) as input power supply
connectors at the same time. Only one connector can be used for input power
supply to the motherboard at one time. For proper use of these proprietary PWR
Connectors, please customize your PWR cables based on the Power Connector
Pin-Out Defi nitions listed on Page 2-14.
Note 2
: The 4-pin Auxiliary PWR Connector is used as a power output to the HDDs
only. Refer to Pages 2-14, 2-15 for more information on power connectors.
