Thanks. I'm brand new to the Dell PE servers, so it took me a while to understand how updates work for the R720xd and IDRAC. I found this article that walked me through upgrading the Lifecycle and IDRAC to2.52.52.52 .Once that was done, I got access to an HTML5 interface, so I don't need the Java client any longer.  I also found Linux ISO for doing updates, I lost the link but it went through and upgraded the firmware on every component, and installed additional components such as the Diagnostics and OS Collector.  The link is here  I was surprised that the Win32 .exe update worked since the server is running Linux, but I guess the iDrac has a way of executing Windows binaries independent of the server's OS, because it worked.       
Using IDRAC 7 Virtual Console , I cannot attached media using the "Launch Virtual Media" menu option. The virtual media windows appears for about 1 second and disappears. In the brief flash I can tell that it see the Firmware update disk that I have mounted on my Mac  but I cannot use it since the virtual media window isn't functional. I read that Java 6 and 7 are supported, so I installed Java 7 plugin for Chrome 66.  The first error I hit was the login error. I was able to get past that by hard-coding the idrac credentials into the .jnlp and relaunching the app.  Error:    After that, the console opens and I can see the remote console of the Dell server.     [IMAGE] Virtual Console version   Error that occurs every time I launch virtual media.  I have vFlash but the upgrade ISO file is 4GB and that only supports 2GB partitions.  Any advice on either fixing the virtual media issue or an easier way to *remotely* upgrade the IDrac would be appreciated.
