Cisco SP-AR3-NC5536XC 24x7x4 Hardware Support Service

Keep the Cisco NCS 5500 36 x 100G MACsec Base Scale Datacenter hardware configuration under a 24x7x4 support level. SP-AR3-NC5536XC provides three years of hardware support with advanced replacement coverage, aligning the service term with infrastructure that must remain available outside standard business hours. The 24x7x4 designation specifies around-the-clock service coverage and a four-hour hardware service target. That level suits routing environments carrying high-capacity 100 Gigabit traffic where a hardware incident needs attention at any hour. Advanced replacement support addresses the hardware element of the covered configuration rather than adding interfaces, capacity, or software features to the installed platform. Use this service when the installed NCS 5500 configuration is the 36 x 100G MACsec Base Scale Datacenter variant named in the coverage description. The service is differentiated by its three-year term, 24-hour and seven-day coverage window, four-hour service level, and hardware-focused advanced replacement scope. It should be matched to the covered system configuration so the service entitlement corresponds to the deployed hardware.
