Pasywny Riser Supermicro 2U LHS 2xPCI-E 2.0 x8 R2U-2E8

The Supermicro R2U-2E8 is a passive riser card designed for 2U server chassis, providing stable PCI Express expansion in environments where reliability and mechanical compatibility are critical. It is intended for standard configurations that do not require GPU, NVMe or M.2 support.

With a left-hand side (LHS) slot position and PCI-E 2.0 x8 interfaces on both input and output, this riser enables horizontal installation of expansion cards in 2U enclosures, optimizing internal space and airflow management.

• Form factor: 2U, LHS slot position
• Category: Standard
• Input interface: PCI-E 2.0 x8
• Output interface: 2x PCI-E 2.0 x8
• Design type: Passive riser (no active electronics)
• GPU support: No
• NVMe support: No
• M.2 support: No
• Thermal sensor: No
• Auto-detection: No

The passive construction minimizes potential points of failure and does not introduce additional power or signal conditioning components. This makes the riser suitable for deployments where predictable signal paths and low complexity are preferred.

Due to the lack of GPU, NVMe and M.2 support, the R2U-2E8 is oriented towards conventional PCI-E expansion cards that operate within the electrical and mechanical limits of PCI-E 2.0 x8. It is intended for compatible 2U Supermicro chassis that support LHS riser configurations.
