Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

JTAG access on SmartNIC K35-S (X10) & K35-Q (X40)

The SmartNIC K35-S & SmartNIC K35-Q have an edge connector available for JTAG connection. The pinout for the edge connector is as follows (T is the top of the board and B is the bottom of the board):

The JTAG signals are 1.8V logic levels. The 1.8V power rail is provided by the card and can be used as a reference. The 12V power rail should normally be left unconnected if the card is powered by a PCIe slot. Care should be taken not to inadvertantly connect JTAG signals to the 12V power rail, which could occur if the connector is plugged in upside-down.
