Step 6 Attach Cables,
J21 Green PC Power
J21 is a two–pin berg that connects to a Green PC–compliant power
supply. When the computer enters a power conserving state, a signal is
sent from this berg to the power supply to permit the power supply to
switch to a low power, high–efficiency mode.
The + on Pin 2 identifies the positive connector.
J28 Reset Switch Connector
J28 is a two–pin single–inline berg that is attached via a cable to an
externally–mounted reset switch.
When the reset switch is pressed, the system performs a hard reset. Pin
1 is ground and Pin 2 is Hard Reset.
J16 Speaker Connector
J16 is a four–pin single–inline berg that is optionally attached via a
cable to a standard system speaker. AMIBIOS signals hardware
problems through the speaker. Pin 1 on the motherboard is identified by
the arrow on the white box around the berg.
