## Summary description

The Supermicro RSC-W2R-88G4 is a 2U rear I/O riser card that provides two PCIe 4.0 x8 expansion slots for compatible Supermicro server chassis. Designed for server environments, it enables installation of additional network, storage or accelerator cards in a 2U system while keeping rear I/O layout. Use cases include expanding server connectivity and adding high-bandwidth peripherals without changing the motherboard.

## Long description

The Supermicro RSC-W2R-88G4 is a 2U rear I/O riser card that provides two PCIe 4.0 x8 expansion slots for compatible Supermicro server chassis. Built for data center and enterprise server systems, this riser preserves the rear I/O layout while enabling installation of additional network, storage, or compute accelerator cards in a compact 2U form factor. The board supports PCIe 4.0 bandwidth at x8 electrical lanes per slot, allowing high-throughput peripherals to operate without modifying the server motherboard.
Advantages
This riser card enables expansion of system capabilities in a 2U chassis without requiring a new motherboard or major chassis modification. By offering two PCIe 4.0 x8 slots in a rear I/O configuration, it supports high-bandwidth devices such as NVMe controllers, 25/40/100 GbE NICs, and accelerator cards while maintaining cooling and cable routing typical for 2U servers. The design prioritizes compatibility with Supermicro chassis and reduces installation complexity for rack deployments.
Suitable for
 Adding high-speed network interface cards (25/40/100 GbE) to 2U Supermicro servers
 Installing NVMe or SAS controller cards for expanded storage connectivity
 Deploying GPU, FPGA, or other accelerator cards that operate at PCIe 4.0 x8
 Upgrading server I/O capacity while preserving rear I/O layout and airflow
Key specifications
 Form factor: 2U rear I/O riser card designed for compatible 2U Supermicro chassis
 Expansion slots: 2 × PCIe 4.0 x8 electrical lanes per slot
 Interface: PCIe 4.0 compatibility (backward compatible with earlier PCIe generations)
 Placement: Rear I/O orientation to maintain chassis rear connector layout
 Cooling considerations: Designed for standard 2U airflow and slot spacing
How to use
Install the riser card into the designated rear I/O riser bay of a compatible 2U Supermicro chassis following the chassis service manual. Secure the riser to the chassis with the provided mounting points and connect any required internal connectors between the riser and motherboard as instructed by the chassis documentation. After physical installation, insert PCIe cards into the riser slots, ensure they are properly seated and secured, then boot the server and verify device detection in the system firmware and operating system. Follow vendor instructions for driver installation and firmware updates for installed expansion cards.
Usage recommendations
Verify chassis compatibility and available power and cooling capacity before installing high-power cards. For optimal performance, use PCIe 4.0-capable expansion cards and up-to-date platform firmware; when mixing generations, expect fallback to lower PCIe speeds. Observe anti-static handling and secure card mounting to prevent damage during operation.
