Introduction

EP16X-PCIE16XG421A is External PCIe x16 (SFF-8674 1x4) to PCIe x16 Gen 4 Switch Host Card, it requires no additional software or drivers to operate.

Utilizing the standard PCI Express Switch, the 36-Lane/20-Port PCI Express Gen 4 Switch provides the most efficient fan-out solution.
The EP16X-PCIE16XG421A supports the following multiple Port configuration options:

  • x16, x16
  • x16, x8 x8
  • x16, x4 x4 x4 x4
  • x16, x4, x4, x2, x2, x2, x2
  • x16, x2, x2, x2, x2, x2, x2, x2, x2
  • x16, x8, x2, x2, x2, x2
  • x16, x8 x4 x4

In particularly rugged environments, your desktop computer can be placed at a secure location up to 100 meters away (using PCIe A.O.C). High-performance and reliable communication are maintained with the well-shielded extension cable or A.O.C (Active Optical Cable).

Note: The device paired with EP16X-PCIE16XG421A must supply 3.3V to the PCIe Gen 4 AOC cable
