Introduction

IP4X-D1X20 is a PCI Express (PCIe) x4 to Four PCIe x1 slots docking system. It provides one upstream port supporting x4, and four downstream ports that support x1 operation. IP4X-D1X20 is integrated by the following three key parts (IP4X-PCIE4XE31, DB525-PCIE2XD1X20, CB-00592).

  • IP4X-PCIE4XE31
    • Internal four PCIe x1 to PCIe x4 Gen 2 Switch Host Card..
  • Two DB525-PCIE2XD1X20
    • Two PCI Express x1 slots Add-On card docking bay.
  • Two CB-00592
    • USB 3.0 2-in-1 Female (10X2_19pin) Cable, L = 60cm.

Utilizing the standard PCI Express Switch, the 8-Lane/5-Port PCI Express Gen 2 (5 GT/s) Switch provides the most efficient fan-out solution for the following configuration:
