57 I2C_AUX_SCL Micro coax The BlueField silicon
serves as the I2C bus
master on this bus.
An I2C EEPROM at
I2C address 0x57
needs to be mounted
on the motherboard
side to report to the
Cabline CA-II Plus
interface parameters
to the main-card
BlueField DPU
silicon, like Cabline
CA-II Plus cables
length (contact
NVIDIA for the
format of this
EEPROM). If
additional optional
I2C slave devices
need to be managed
by the main-card
BlueField DPU
silicon, they need to
be included on this
I2C bus as well.
