2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express 2.0 x16: this connector supports simultaneous transfer speeds of
up to 8 GB/s of peak bandwidth per direction.
• One PCI Express 1.1 x1: each of these connectors support simultaneous transfer
speeds of up to 500 MB/s of peak bandwidth per direction.
• Two Conventional PCI bus (rev 2.3 compliant) connectors.
Note the following considerations for the Conventional PCI bus connectors:
• All of the Conventional PCI bus connectors are bus master capable.
• SMBus signals are routed to all Conventional PCI bus connectors. This enables
Conventional PCI bus add-in boards with SMBus support to access sensor data on
the 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.
