Description
Pin# on the
other end
60 S_PRSNT2_L Micro coax 38 Connect to a 4.7K
pull-up resistor to
3.3V on the
motherboard side, to
detect if both the
Cabline harnesses
are connected or
not. This signal is
connected to
S_PRSNT1_L on the
BlueField DPU. In the
motherboard side,
read logic low if
both Cabline
harnesses are
connected. Read
logic 1 (3.3V) if one
or both the Cabline
harnesses are not
connected.
No wires are
connected to these
pins to ensure they
do not interfere with
the operation of
S_PRSNT1_L for the
detection when the
two Cabline
harnesses are
installed.
