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
network adapter main
card. 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.
