looking for options on how to remotely turn on an dell r320 remotely when it has been shutdown due to loss of power. We did not purchase the addition idrac licensing but  I see there is the System Bios AC POwer Recovery settings. We use Dell Open Essentials which has Remote Power tasks, which allows us to turn of a server remotely but need the remote access to turn on, which I assume that we need the licensing for idrac to do this?
