Hi [NAME],   Warranty extension for Dell S4048 would be 5 years from purchase date. Any longer than that, there is no further extension. End of support would be at year 2027 for S4047: [URL] Please do refer the EoSS conditions at the end of the article. *After EoSS, existing software updates and fixes/patches will continue to be available, but Dell Technologies will provide no further software maintenance or updates*. If there is any enquiry or doubt about the warranty descriptions, please do consult your vendor.    
Is it true that Dell S4048 switch end support has been announced and it cannot be extended anymore? I just wanted to make sure that my vendor is not pushing me to buy new switches ..
