Motherboard Connections
This section describes the connections on the motherboard and provides pinout definitions.
Note that depending on how the system is configured, not all connections are required. The
LEDs on the motherboard are also described here. A serverboard layout indicating component
locations may be found in Appendix B.

4.1 Power Connections
Required Connection
Important:
To provide adequate power to the motherboard, connect the 24-pin
and
the 8-pin
power connectors to the power supply. Failure to do so may void the manufacturer's warranty
on your power supply and motherboard.
ATX Power Supply Connector
The primary 24-pin power supply connector (JPW1) meets the ATX SSI EPS 12V specification.
An 8-pin (JPW2) processor power connector must also be connected to your power supply.
