S_PERST1_CONN_L
Micro coax 38 PCIe compliant
PERST_L (active low
PCI Reset) signal for
the PCIe Cabline CA-
II Plus Connectors.
The direction of this
PERST_L signal
depends on the
implementation:
When connecting a
CPU root complex to
the PCIe Cabline CA-
II Plus interface, this
signal is driven from
the motherboard
side (from the CPU),
to the network
adapter. When
connecting a GPU or
an end point to the
PCIe Cabline CA-II
Plus interface, this
signal is driven from
the network adapter
side (which operates
as a PCIe switch in
this case), to the
GPU or end-point on
the motherboard
side.
