Cisco DNAC1 ESS Term C3850 48P Fiber 3Y | On-site Replacement Support — C38505-DNAC1E-3Y

Keep critical network access available with Cisco support for Catalyst 3850 48-port fiber deployments over a 3-year term. This service is built for infrastructure teams that need fast response, clear escalation paths, and hardware replacement when a fault threatens user access or business operations. The value is operational continuity. Phone support gives your team a direct path to troubleshooting, while on-site replacement reduces the time between failure and recovery. For access-layer switching, that difference matters: it protects connectivity for users, endpoints, and downstream services that depend on stable network performance. A 3-year term also simplifies planning. It aligns support coverage with refresh cycles, helps control lifecycle costs, and gives procurement a defined service window for budgeting. For organizations running Cisco switching in production, this is the kind of support package that justifies itself the first time a failed component would otherwise become an outage.
