QIP2X-PCIE8XG302 is a fully non-blocking, low-latency, low-power 16-Lane, 5-Port PCIe Gen 3 Switch Host Card.

The PCIe Gen 3 Switch (16-Lane, 5-Port) allows users to take advantage of a single PCIe x8 slot, through the use of QIP2X-PCIE8XG302, and transform their PCIe slot into the following modes:

  • Two PCIe Slots (x4, x4)
  • Four PCIe Slots (x2, x2, x2, x2)

The flexible hardware configuration and software programmability allows the switch to be tailored for a wide variety of application.
QIP2X-PCIE8XG302 supports Port configuration options:
