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 dis-
charge ESD in a suitably configure backplane connector.
4. Pins P5 and P6 are not connected internally to the device but there is an option to connect through a zero ohm stuffing
resistor. 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.
