Lenovo 4M17A61348 SR630 AIR Duct KIT V2

Lenovo 4M17A61348 SR630 Air Duct Kit V2

Overview

The Lenovo 4M17A61348 is a replacement and expansion air duct kit (V2) for the ThinkSystem SR630 rack server. Air ducts in 1U servers are not optional aesthetics — they channel airflow from front intake fans directly over processors, DIMMs, and PCIe components, preventing recirculation that causes thermal throttling and shortens component life. If your SR630 has an open processor socket, an unpopulated DIMM bank, or a vacant PCIe riser slot, the missing duct creates a low-resistance bypass that starves the populated components of cooling. The 4M17A61348 closes that gap.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR630 1U rack server platform. Verify your SR630's chassis revision and processor/riser configuration before ordering — Lenovo's SR630 line uses multiple duct variants keyed to specific CPU TDP envelopes and riser configurations. The V2 designation indicates a revised geometry; confirm against your system's Hardware Maintenance Manual or the FRU list for your chassis serial range to ensure this is the correct duct for your specific server configuration. Do not assume interchangeability with V1 ducts or ducts from the SR630 V2/SR630 V3 generation if those are separate platforms.

Installation Notes

Installation is tool-free on the SR630 — the duct clips into the chassis guides and seats without fasteners. Power down the server and remove it from the rack before installing; airflow management components must be seated before powering on. Do not operate the SR630 with duct positions left open — Lenovo's thermal validation requires all duct slots populated. Weight is 1.0 lb, consistent with a single-piece molded plastic duct assembly.
