But automatic restart is most-often dependent on having "good" batteries at the moment power is restored. Pages show some shutdown sequence cases, particularly on page 36, which shows a great graph.īrand Representative for Tripp Lite.
Imagine a UPS with no battery turning off and on again repeatedly in sequence with the incoming power, hard crashing your IT equipment over and over again. This is largely due to the fact that Eaton and other manufacturers have load protection guarantees and we don't think that turning your IT equipment without battery is a good idea from experience. This ensures the UPS will auto-reboot when it senses power return, even if power returns in the middle of a shutdown. At Eaton, we have a sequential shutdown startup procedure to make sure the UPS turns off after the graceful shutdown command is sent. Use that instead of "last state".įrom my experience, almost all UPSs will automatically restart when power is restored. I've seen both APC and Cyberpower units act this way after a prolonged outage.

There are tons of how-to articles and videos on the 'net. If your computer's was manufactured after aboutits Ethernet adapter and motherboard almost certainly support WOL. I don't know of a UPS that isn't designed to power itself up, supply power to connected equipment and start recharging its battery once power is restored after an outage. I'm going to need to put a UPS in a remote location - I have remote reboot modules, and am aware some UPS's have relays that control the loads or banks of outlets, but here is the scenario I'm thinking ahead on Answer to question 1: yes.
