Pasywny Riser Supermicro 2U LHS 2xPCI-E 2.0 x8 R2UU-2E8

The Supermicro R2UU-2E8 is a passive riser card designed for 2U server platforms in UIO configurations. It provides two PCI-E 2.0 x8 slots with left-hand side (LHS) positioning, enabling horizontal installation of compatible expansion cards in space-constrained 2U chassis.

Thanks to passive signal routing, the riser does not introduce active components into the PCIe path, supporting stable and predictable operation in environments where reliability and mechanical compatibility are critical.

• Form factor: Dedicated to 2U chassis (UIO category)
• Slot position: LHS (Left-Hand Side) for side-mounted expansion cards
• Output type: 2x PCI-E x8 (PCI Express 2.0)
• Input type: PCI-E x8 interface to the motherboard
• Design: Passive riser – no active signal conditioning components
• GPU support: Not supported
• NVMe support: Not supported
• M.2 support: Not supported
• Thermal sensor: Not available
• Auto-detection: Not available

This riser is intended for use in systems where precise mechanical fit and defined slot orientation are required. It is suitable for integrating compatible PCIe x8 expansion cards, such as selected network or controller cards, provided they match the mechanical and electrical specifications of the host platform and chassis.

Before deployment, verify motherboard and chassis compatibility with the specific R2UU-2E8 riser model, as well as the mechanical clearance for installed expansion cards within a 2U environment.
