This method doesn't seem acccurate anymore. I also have a 2062 and wanted to shutdown. There isn't the mentioned shutdown options as you state from the SMU.
When you log in to the SMU there isn't a "System's" tab, there are four menu options Dashboard, Provissioning, Settings and Maintenance. Under Settings there is a System option. but this is just an area to set up some very basic system settings such as System Name, Date/Time, turn on things like SMART, or adjust drive cache. Nothing at all to do with Restarting or Shutdown.
If you navigate to Maintencance > Hardware > Eclosure there is a drop down called "Actions" where you can choose Shutdown/Restart and you are given the following options.

You can shut down controllers, you restart controllers, and you can restart the management controller but nothing at all to just shutdown the Enclosure. There was a reddit post that says you can't gracefully shutdown MSA remotely you just have to stop IO (is shut down any connected hosts and then press the power button to turn it off I am not convinced this is correct as you can't be sure no parity writes etc are doing on on the disks and end up forcing things like disk scrubbing on your array which you would have if you just turned the power off.
So any ideas what the actual correct method for shutting down is, the text in that popup talkins about shutting down the controllers needs to be done before powering off its enclosure but how to porperly power off the enclosure I don't know.
