Maintain the service position of a Cisco UCS 5108 AC Chassis with this 8x5xNBD hardware support offering. It applies to the AC chassis configuration with an updated backplane, helping administrators align the service entitlement to the installed UCS chassis rather than to an individual blade server or fabric component. The 8x5 designation identifies weekday business-hours coverage, while NBD identifies the next-business-day service level. CON-NCDT-6508AC2 is associated specifically with the UCS 5108 AC chassis platform named in its service description. That platform relationship matters in modular UCS domains, where the chassis, server blades, fabric extenders, and interconnects are separate hardware elements. Match the supported chassis configuration and backplane revision before assigning service coverage so the entitlement corresponds to the installed infrastructure. This service option suits UCS chassis deployments supporting virtualized compute pools, application clusters, and other shared server environments where a chassis-level hardware event can affect multiple blades. Its defined 8x5xNBD level provides a clear support schedule for organizations that do not require round-the-clock coverage. Keep the chassis serial and installed configuration available when opening a support request to ensure the request is associated with the covered platform.
