For faster parts replacement than is provided with the standard Cisco Unified Computing System warranty, you can purchase the Cisco Unified Computing Warranty Plus. You can choose from several levels of advanced parts replacement coverage, including onsite parts availability in as little as two hours. Onsite part arrival times can vary based on location. Warranty Plus provides anytime, remote access to Cisco support professionals, who can determine if a return materials authorization (RMA) is required. Many IT organizations find that this is the right level of support for a preproduction pilot or lab testing of their Cisco UCS solution.
