58 I2C_AUX_SDA Micro coax The ConnectX-7
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
network adapter
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
network adapter
silicon, they need to
be included on this
I2C bus as well.

No wires are
connected to these
pins to ensure they
do not interfere with
the operation of
S_PRSNT2_L for the
detection when the
two Cabline
harnesses are
installed.
