One Stop Systems OSS-PCIE-HIB38-X4 PCIe x4 Gen3 Swtich-Based Cable Adapter - iPass Connector
PCIe cable adapters install easily into a computer's PCIe slot. A PCIe cable can then be plugged into the adapter to extend the PCIe bus from the motherboard to an external device, like an expansion enclosure or storage device. The PCIe x4 adapter has an 12-lane switch with built-in DMA controller and extends the PCIe bus at 32Gb/s with extremely low latency because there is no conversion software.
The host adapter installs in the host computer's PCIe x4 I/O slot, allowing communication between the processor and multiple I/O points
Insert the host cable adapter into a PCIe x4 in the host system slot. Make sure that the card is well seated and tighten the screw on the face plate. Attach the cable by inserting the cable into the slot and pushing on the metal tab to raise the metal pins. Release the metal tab ones the pins are aligned with the pin holes.
