Maintain service coverage for a Cisco UCS 9508 chassis with five years of Smart Net Total Care support. The service level combines 24x7 access to Cisco technical support with a four-hour onsite service response target. It applies to the UCS 9508 chassis rather than to a generic compute-support tier, helping administrators align the entitlement to the chassis installed in their UCS domain. Cisco CON-5OSP-UCXSX958 is suited to data center environments where the modular chassis is a central platform for compute operations and support escalation cannot be limited to standard business hours. The 24x7 support characteristic provides a path for incident assistance at any hour, while the 4-hour onsite designation addresses situations requiring an onsite service response for covered hardware events. The five-year term distinguishes this coverage from shorter-duration support selections for the same chassis family. Its 24x7x4 onsite level is intended for installations that need a defined response commitment beyond remote technical assistance alone. Use the chassis serial and installed configuration when associating coverage, since the entitlement is specifically named for the UCS 9508 chassis.
