if not, then it's a moot point. WOL proxies are used for just this.
That said, why in DS 6.9 would you even WANT to initiate a job if the system is down? It wont get to the system and will fail. DS 6.9 operates in real-time, not with schedules.
Now, if you were using Software Delivery in NS 7.x, that does instigate jobs whether or not the system is on. It's a nice added feature of the new integration to NS that DS is taking. Comes at a cost, granted, but still a nice feature.
