I have ZD3050 with additional 50 AP with following licenses:
901-3050-EU00 - ZoneDirector 3000, licensed for up to 50
909-0050-ZD00 - ZoneDirector 3000 License Upgrade support
802-3050-1000 - Partner WatchDog Premium Support for ZoneDirector
802-3050-1L00 - Partner WatchDog Premium Support for ZoneDirector
+ licenses for SPoT purpose.
I've got warning about expiring my Support Service:
"The Support Service on this ZoneDirector will expire in  days. An active Support service entitles you to future firmware upgrades. Please contact Ruckus Support
for further assistance. [What's this?]
To renew support service i download SPT file following that instruction:https://support.ruckuswireless.com/answers/000003546
Unfotunately when I want to upload file in Administer/Support on my ZD I've got message:
"ZoneDirector already has the latest Support Entitlement file" and warning about expiration still shows up
Can you help me guys with this issue?
