Provide four years of PSS coverage for the specified Extreme Networks 5420M switch configuration. This service part combines next-business-day handling with advanced hardware replacement and an online RMA service path. It is a support entitlement for covered hardware rather than a switch, interface expansion, or software feature. The 94304-5420M-16MW-32P-4YE-TAA ordering code applies to the 94304-5420M-16MW-32P-4YE service model. The model association matters because the service is tied to the named 5420M configuration. Use the complete ordering code when matching an existing support requirement that calls for a four-year term, next-business-day replacement handling, and advanced replacement coverage. Advanced hardware replacement supports restoration planning when a covered hardware fault requires replacement equipment. Next-business-day handling distinguishes this service from a replacement arrangement without a stated next-business-day designation, while the online RMA component identifies the return-material authorization path. The four-year period makes the service suitable where the covered 5420M configuration will remain installed through a defined support interval and requires continued replacement coverage.
