Choose 94311-AP4020-WW-TAA when the required coverage for an Extreme Networks AP4020-WW-TAA access point is next-business-day onsite RMA service. The code associates that service entitlement with the 94311-AP4020 product designation. NBD denotes the next-business-day service level, onsite identifies the service location, and RMA-only identifies return-material-authorization service as the coverage scope. It is a service item rather than an access point. It does not add access-point hardware, software licensing, installation, configuration, or consulting. This entitlement suits deployments that need the named replacement-service path rather than hardware supply or project services.
