The M620 would have an iDRAC7, which provided is on the latest firmware, will support an HTML5 viewing window. You'll need to make sure to set the Plug-in type to HTML5 at Overview > Server > Virtual Console.
Good afternoon! I have a Dell Inc. blade basket PowerEdge M620 I'm trying to start the console, but I get this error "Unable to launch the application". I tried to edit the security java file, as in this instruction, but the error remained. What else can I do, can I upgrade and get an HTML version?
Error starting console
