Lenovo 4X97B02316 SR650/A V4 X8 G5 Cable Riser Slot 3 & 6

Overview

The Lenovo 4X97B02316 is a PCIe cable riser assembly designed for the ThinkSystem SR650/A V4 server platform. It provisions Slot 3 and Slot 6 with an x8 Gen 5 interface, giving you additional PCIe expansion capacity in a two-socket 2U chassis where rear-slot routing and cable management are constrained by dense NVMe and I/O configurations. If your SR650/A V4 build requires expansion cards beyond the front-loaded risers — GPU pass-through, additional HBAs, or high-bandwidth NICs — this riser is the mechanical and electrical bridge that makes Slot 3 and Slot 6 available in that position.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V4 and SR650A V4 rack servers. The x8 Gen 5 electrical interface targets PCIe 5.0 adapters while maintaining backward compatibility with Gen 4 and Gen 3 cards at their respective speeds — important if you're mixing a Gen 5 NIC with an existing Gen 4 HBA in the same chassis. This riser is not interchangeable with SR650 V2 or V3 cable risers; the V4 platform uses a revised mechanical footprint and connector layout. Confirm the target server's service manual slot map before ordering to avoid a mismatch between physical slot numbering and riser position.

Installation Notes

Weighs 1.00 lb — lightweight enough for single-technician installation without a lift assist. Manufactured in Mexico (MX) and sourced factory-new as a genuine Lenovo server accessory. Follow the SR650/A V4 hardware maintenance guide for correct riser seating sequence; improper insertion order with populated PCIe cards can stress the riser connector. No additional power connectors are required beyond what the riser cable routes to the system board.
