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

Please review the Safety Precautions in Chapter 3 before installing or removing components.

Main ATX Power Connector
The primary power connector (JPW1) meets the ATX SSI EPS 12V-pin specification. You must
also connect the 8-pin (JPW2) processor power connector to your power supply (see below).
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.
