Technical Reference 2.2.2.2 Add-in Card Connectors The board has the following add-in card connectors: • PCI Express 2.0 x16: two PCI Express 2.0 x16 connectors supporting simultaneous transfer speeds up to 8 GB/sec of peak bandwidth per direction and up to 16 GB/sec concurrent bandwidth. • PCI Express 1.1 x1: three PCI Express 1.1 x1 connectors. The x1 interface supports simultaneous transfer speeds up to 250 MB/sec of peak bandwidth per direction and up to 2 GB/sec concurrent bandwidth. • Conventional PCI (rev 2.3 compliant) bus: one Conventional PCI bus add-in card connector. The SMBus is routed to the Conventional PCI bus connector. Conventional PCI bus add-in cards with SMBus support can access sensor data and other information residing on the board. Note the following considerations for the Conventional PCI bus connector: • The Conventional PCI bus connector is bus master capable. • SMBus signals are routed to the Conventional PCI bus connector. 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. 2.2.2.3 Auxiliary Front Panel Power/Sleep LED Header Pins 1 and 3 of this header duplicate the signals on pins 2 and 4 of the front panel header.

2.2.2.2
Add-in Card Connectors
The board has the following add-in card connectors:
•
PCI Express 2.0 x16:
two PCI Express 2.0 x16 connectors supporting
simultaneous transfer speeds up to 8 GB/sec of peak bandwidth per direction and
up to 16 GB/sec concurrent bandwidth.
•
PCI Express 1.1 x1:
three PCI Express 1.1 x1 connectors.
The x1 interface
supports simultaneous transfer speeds up to 250 MB/sec of peak bandwidth per
direction and up to 2 GB/sec concurrent bandwidth.
•
Conventional PCI (rev 2.3 compliant) bus:
one Conventional PCI bus add-in card
connector.
The SMBus is routed to the Conventional PCI bus connector
.
Conventional PCI bus add-in cards with SMBus support can access sensor data and
other information residing on the board.
Note the following considerations for the Conventional PCI bus connector:
•
The Conventional PCI bus connector is bus master capable.
•
SMBus signals are routed to the Conventional PCI bus connector.
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.
