Add 4-hour onsite response coverage to an Extreme Networks 97008-5520-48T-ACDC-BASE environment through an ExtremeWorks service entitlement. Onsite support is intended for incidents that require physical attention at the deployment location, providing a defined escalation path beyond remote troubleshooting. The service is classified for Extreme Networks hardware support and is delivered at the customer site. The 97008-5520-48T-ACDC-BASE-TAA ordering code identifies the TAA variant of this 4-hour onsite service. Match the service entitlement to the supported 97008-5520-48T-ACDC-BASE platform before ordering. This naming distinction matters where the ordering code, support target, and TAA requirement must be recorded accurately in the installed-service inventory. Use this service where operational requirements call for onsite assistance with a four-hour response objective. It fits network environments where physical hardware assessment, replacement activity, or other site-based support tasks may be needed after a support case is evaluated. The entitlement concerns support coverage rather than a network hardware component, so it should be paired with the corresponding covered Extreme Networks platform.
