Hi,
No, you get 3 years standard warranty on hadware. This is software maintenance for the OS, I believe its about $9 AU per unit and it can be ordered from any Wyse reseller (check it out with whom ever you buy your Wyse gear from).
If they don’t know the part number call Wyse direct and although they don’t do direct sales they can give you all the info,
Cheers,
