Caution: Only the back panel USB, front panel USB, VGA, and PS/2 connectors have over current protection. The Intel® Desktop Board D845GLAD internal connectors are not over current 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 interconnecting cable, and the external devices themselves.
This section describes the board's connectors. The connectors can be divided into the following groups:
Integrator's Note: When installing the Desktop Board in a microATX chassis, make sure that peripheral devices are installed at least 1.5 inches above the main power connector, the diskette drive connector, the IDE connector, and the DIMM sockets.
Back Panel I/O 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.

Integrator's 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.
Internal I/O Connectors
The internal I/O connectors are divided into the following functional groups:
Audio, Power, and Hardware Control
The figure below shows the location of the audio, power, and hardware control connectors.

Add-in Board and Peripheral Interface Connectors
The figure below shows the location of the add-in board connector and peripheral connectors for the Intel Desktop Board D845GLAD. Note the following considerations for the PCI bus connectors: - All of the PCI bus connectors are bus master capable.
- SMBus signals 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.

Integrator's Note: Not all PCI video cards can be used in PCI bus connectors 1 and 2 (the PCI bus connectors closest to the processor). To avoid clearance problems, install PCI video cards in PCI bus connector 3.
External I/O Connectors
