This is a Lenovo Data Center Group (DCG) Post-Warranty Service contract — 'PW Tech Install' — providing a technician-installed hardware service after a server or storage system's original manufacturer warranty has expired, with a 24x7 6-hour Committed Service Repair (CSR) response commitment. Rather than a physical product, it's a support/maintenance line item that extends professional break-fix coverage (a technician physically installing replacement parts) on already-deployed Lenovo enterprise equipment, sold to businesses wanting to keep older ThinkSystem/ThinkAgile hardware supported without buying new equipment. The catalog listing doesn't specify which particular piece of hardware this contract applies to — that would be tied to the customer's existing equipment at time of purchase.
