Connectors

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

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.

This section describes the board's connectors and are divided into these groups:

Back Panel I/O Connectors
Internal I/O Connectors
External I/O Connectors
Back Panel Connectors
The figure below shows the location of the back panel connectors. The back panel connectors are color-coded in compliance with PC 99 recommendations. The figure legend below lists the colors used.

Add-in Board and Peripheral Interface Connectors
The figure below shows the location of the add-in board connector and peripheral connectors for the Desktop Board D865GVHZ. Note the following considerations for the PCI bus connectors:
All of the PCI bus connectors are bus master capable.
SMBus signals are routed to PCI bus connector 2. This enables PCI 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
