4.2 Signal Descriptions
4.2.1 Connector Pin Signal Definitions
Note: Key and spacing separate signal and power segments.
4.2.2 Power Pin Signal Definitions
Notes:
1. All mate sequences assume zero angular offset between connectors.
2. P1 and P2 are internally connected to one another within the device.
3. Ground connectors P3 and P4 may contact before the other 1st mate pins in both the power and signal connectors to
discharge ESD in a suitably configure backplane connector.
4. P5 and P6 are not connected internally to the device. The host may put 5V on these pins.
5. The host may ground P7 if it is not used for Device Activity Signal (DAS).
6. P8 and P9 should not be connected by the host.
