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
