In order to connect a host PC to the Console RJ45 port of the system, a RS232 harness cable (DB9 to RJ45) is supplied.

Important

RJ-45 Console and I²C interfaces are integrated in the same connector. Due to that, connecting any cable other than the NVIDIA supplied console cable may cause an I²C hang.

Using uncertified cables may damage the I²C interface. Refer to the Replacement Parts Ordering Numbers appendix for harness details.
