[SOLVED] What happen if SAS/SATA TX link to TX?

[Enshuo]

Basically, the signal should be TX -> RX from 4 * mini-SAS HD to 16 * SATA connector, but there is a wrong pinout on the backplane. The link is TX -> TX and RX -> RX now. What will happen in this case such as malfunction, can't receive any data, etc.? Is there any automatic reverse mechanism?

The current design is the opposite:

One more question: The S2/S3 of U.2 SFF-8693 are different from SAS SFF-8482. So which link is right? The SATA0_TX from SFF-8643 cable should connect to S2/S3 or S5/S6 on backplane?
