I tried to find the way to shut down the Appliance by GUI or CLI but cannot got it in FMC 750.
Attached some possible ways for your reference but they do not have shut down appliance option. In Greenshot 20201029091449.jpg, it shows only management centre. In Greenshot 20201029091511.jpg, it has no Power Off option.
May I have your advise as soon as possible as today afternoon, I have to shutdown them. Thanks!
