This is a Lenovo support service SKU, not a physical product: a 1-year Foundation Service contract that begins after the standard warranty ends ("Post Wty"), providing Next Business Day (NBD) on-site response for a Lenovo ThinkSystem SR650 rack server. Foundation Service is Lenovo's entry-level post-warranty support tier — it extends hardware support coverage with a guaranteed next-business-day technician response for a confirmed failure, rather than leaving the server unsupported once its original warranty lapses. This is bought alongside or shortly before an SR650's original warranty expires, by IT departments or data centres that want continued vendor-backed support on an existing server rather than replacing it, and it has no function on its own without a qualifying SR650 already in service.
