CAUTION
Only the following connectors have overcurrent protection: back panel USB, front panel USB, and PS/2*.

The other internal connectors are not overcurrent protected and should connect only to devices inside the computer's chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computer's chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves.
Back Panel Connectors

The figure below shows the location of the back panel connectors. The back panel connectors are color-coded. The figure legend below lists the colors used (when applicable).

D945PAW Back Panel Connectors
Item Description Color
A PS/2* mouse port Green
B PS/2 keyboard port Purple
C Serial port A Teal
D Parallel port Burgundy
E USB ports (two)  
F IEEE-1394a connectors (optional)  
G LAN  
H USB ports (two)  
I Audio line in/Retasking Jack Blue
J Mic in/Retasking Jack Pink
K Front left/right channel audio out/Two channel audio line out/Retasking Jack Lime green
Note
The back panel audio line out connector is designed to power headphones or amplified speakers only. Poor audio quality occurs if passive (non-amplified) speakers are connected to this output.
Component-side Connectors

Add-in Card Connectors
The board has the following add-in card connectors:
PCI Express* x16: one connector supporting simultaneous transfer speeds up to 8 GBytes/sec.
PCI Express x1: one PCI Express x1 connectors. The x1 interface supports simultaneous transfer speeds up to 500 MBytes/sec.
PCI Conventional* (rev 2.3 compliant) bus: two PCI Conventional bus add-in card connectors. The SMBus is routed to PCI Conventional bus connector 2 only. PCI Conventional bus add-in cards with SMBus support can access sensor data and other information residing on the board.
Note the following considerations for the PCI Conventional bus connectors:
All of the PCI Conventional bus connectors are bus master capable.
SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI Conventional bus add-in boards with SMBus support to access sensor data on the Desktop Board. The specific SMBus signals are as follows:
The SMBus clock line is connected to pin A40.
The SMBus data line is connected to pin A41.
Note
The PCI Express x16 connector is configured to support only a PCI Express x1 link when the Intel® GMA950 graphics controller is enabled.

D945PAW Front Panel

Front Panel USB Connectors
The figure below is a connection diagram for the front panel USB connectors.
Integrator's Notes
The +5 V DC power on the USB connector is fused.
Pins 1, 3, 5, and 7 comprise one USB port.
Pins 2, 4, 6, and 8 comprise one USB port.
Use only a front panel USB connector that conforms to the USB 2.0 specification for high-speed USB devices.

D945PAW Front Panel USB Connector

Front Panel IEEE 1394a Connectors (Optional)
The figure below is a connection diagram for the optional IEEE 1394a connectors.

D945PAW IEEE1394a Connector

Integrator's Notes
The IEEE 1394a connectors are colored blue.
The +12 V DC power on the IEEE 1394a connectors is fused.
Each IEEE 1394a connector provides one IEEE 1394a port.
