2.8.2.4 Add-in Board and Peripheral Interface Connectors
Figure 19 shows the location of the add-in board and peripheral connectors for the Desktop Board
D875PBZ. Note the following considerations for the PCI bus connectors:
• All of the PCI bus connectors are bus master capable.
• The SMBus is routed to PCI bus connector 2. This enables PCI bus add-in boards with SMBus
support to access sensor data on the Desktop Board D875PBZ. 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
