56 S_WAKE1_CONN_L Micro coax In setups that
support operation of
the network adapter
card during standby
operating mode, this
optional PCIe
compliant Wake
signal, may be used
for the network
adapter silicon to
indicate to the
motherboard when
wake from standby
power mode, for
example after a
magic packet was
received. Please
consult NVIDA in
case of intention to
use this signal, as it
has not been
populated or used in
designs so far.

57 I2C_AUX_SCL 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.
