Intel Desktop Board D201GLY Technical Product Specification 2.2.2.1 Power Supply Connectors The board has the following power supply connectors: • Main power - a 2 x 10 connector. The board supports the use of ATX12V power supplies with 2 x 10 or 2 x 12 main power cables. • ATX12V power - a 2 x 2 connector. This connector provides power directly to the processor voltage regulator and must always be used. Failure to do so will prevent the board from booting. Table 14.

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 connector: • The PCI Conventional bus connector is bus master capable. • SMBus signals are routed to the PCI Conventional bus connector. 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. ⎯ The SMBus data line is connected to pin A41. 40

2.2.2.1
Power Supply Connectors
The board has the following power supply connectors:
•
Main power
– a 2 x 10 connector.
The board supports the use of ATX12V power
supplies with 2 x 10 or 2 x 12 main power cables.
•
ATX12V power
– a 2 x 2 connector.
This connector provides power directly to
the processor voltage regulator and must always be used.
Failure to do so will
prevent the board from booting.

Add-in Card Connectors
The board has one PCI Conventional (rev 2.3 compliant) bus add-in card connector.
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 connector:
•
The PCI Conventional bus connector is bus master capable.
•
SMBus signals are routed to the PCI Conventional bus connector.
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.
⎯
The SMBus data line is connected to pin A41.
