displayed with OK button for you to continue.
NOTE: For le server, the continue button is displayed with its own

• In a secured environment, such as le server and WDM using HTTPS, with previous clients upgraded to new rmware from le server,
by default, the clients follow the new global SSL security mode, and the default value is set to Warning, if no value is set using the INI
parameter. Dell recommends you to install required certicates on all clients before rmware upgrade. If required certicates are not
propagated to clients, then you must see the displayed warning message during system boot up, such as click OK or continue, and
select the preferred option.
• In an un-secured environment, such as le server and WDM using ftp/http protocol, after rmware update or boot up with factory
default settings, the client connects to the le server in ftp protocol without any warning message.
• Dell recommends you to dene the Security Policy before upgrading to version 8.3. If not, you may get warning messages that require
intervention to proceed.
Improved user friendly messages are displayed for errors and warnings. The UI is not changed and only the message is modied for security
errors/warnings.
