Pasywny Riser Supermicro 2U RHS 2xPCI-E x8 R2UW-2E4R

The Supermicro 2U RHS 2xPCI-E x8 R2UW-2E4R is a passive riser card designed for WIO platforms and 2U rackmount chassis. It provides a right-hand-side (RHS) slot position and enables expansion of PCI Express devices in dense server environments.

This riser offers two PCI-E x8 output slots from a PCI-E x4 input, allowing flexible deployment of compatible PCIe adapters where space and airflow are constrained. As a passive design, it relies on the host system for signal integrity and power delivery, ensuring low complexity and high reliability.

• Form factor: Dedicated for 2U chassis (RHS position)
• Category: WIO
• Output type: 2x PCI-E x8
• Input type: PCI-E x4
• Design: Passive riser
• Automatic detection: Yes
• GPU support: No
• NVMe support: No
• M.2 support: No
• Thermal sensor: No

The R2UW-2E4R is intended for scenarios where stable, predictable PCIe connectivity is required without additional active components. The lack of GPU, NVMe and M.2 support simplifies integration and reduces the risk of incompatibilities in standardized server configurations.

By leveraging automatic detection, the system can correctly recognize the riser and its connected PCIe devices, streamlining deployment and maintenance in data center and enterprise environments.
