Notes: For J6 and J3/J4: PCIe Reference Clock is not forwarded through the PCIe External Cable 3.0.
Other sideband signals from slot connector such as PERST#, WAKE#, CLKREQ# are not forwarded through the external cable
interface. Outputs are provided in the adapter for debug purposes.
Access to I
2
C Bus
The I
2
C bus is connected from the PCIe Bus card slot to the PCIe External Cable 3.0 to PCIe Slot Adapter
connector J22: Port 0 and J16.
J16 provides access to I
2
C/SMBus signals from the PCIe slot for other I
2
C analysis equipment. See
Table 2
below,
for the I
2
C connections on J16.
