Auxiliary Front Panel Power/Sleep Led Connector; Front Panel Connector - Intel BLKD101GGCL Specification

Intel Desktop Board D101GGC Technical Product Specification
2.7.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
•
PCI Express x16: one connector supporting simultaneous transfer speeds up to 8 GBytes/sec.
•
PCI Express x1: one PCI Express x1 connector. The x1 interface supports simultaneous
transfer speeds up to 500 MBytes/sec.
•
PCI Conventional (rev 2.3 compliant) bus: two PCI Conventional bus add-in card connectors.
The SMBus is routed to PCI Conventional bus connector 2 only (ATX expansion slot 6). PCI
Conventional bus add-in cards with SMBus support can access sensor data and other
information residing on the board.
Note the following considerations for the PCI Conventional bus connectors:
•
All of the PCI Conventional bus connectors are bus master capable.
•
SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI
Conventional 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.
