Fortunately I already have UPS on both dome and roll off roof observatories. I am just trying to relieve the need to have computers powering up full time. The power and wear on the power supplies of the computers being the primary considerations. I checked one systems manual tonight and that supports power on for power loss. So I can test this over the Christmas break to see if it will work. This will be the final redundancy measure in place. I can then choose to have the computers off or on at my will. Redundancy becomes really important for remote systems. This one had me stumped but now it seems I will have this sorted, thanks to you guys.
