During a power outage, how do the three servers in the basement react?

Over the weekend, some branches fell on a neighbor’s power service line. They still had power, but the branches had to be removed. That removal occurred this morning. I saw the trucks at about 6:45 AM as I walked past. I suspected I might lose power, and I did. This post records the shutdown and power on times/sequences. I might find this useful should I need to reevaluate the power-outage procedures. My thought: Perhaps just shutdown the big servers, but keep the gateway, wireless access points, and switches running. The goal being: shutdown the heavy stuff, keep the light stuff going, perhaps for an hour or so. The actual time, I don’t know because I’ve never tried. I could judge that based on power consumption by those units… the information is all there in the PDU graphs… In this post: FreeBSD 15.0 nut-2.8.5_1 gw01 /var/log/messages shows: Jul 6 11:09:53 gw01 upsmon[3974]: UPS heartbeat on line power Jul 6 11:09:58 gw01 upsmon[3974]: UPS ups04 on battery Jul 6 11:14:53 gw01…
