The part about the switchgear vendor deciding to do something a certain way that the customer didn't want because it can cause a rare failure reminded me of something that happened to me. Way back I bought a 1500VA UPS that was not an APC but still a known brand to protect my home server. The decision was based on cost as it was significantly less money. One night I was near the server when the power went out. So I sat there waiting to see the auto shutdown. Soon enough the UPS told the server to shutdown and it was well on it's way to power off. Just before it shut off the power came back. And the UPS stopped beeping and went back to normal operation... while the server completed shutdown. And know I have a server that's off and if I wasn't around I would have not known what happened. When I got the UPS I just did one test to make sure the server shut off and the UPS shut itself off without draining its batteries. This meant that I plugged it back in AFTER the UPS powered off. I never considered that the manufacturer of the UPS would botch the power restored after telling the server to shut down sequence. I contacted the manufacturer about this. I told them that after telling the server to shut down there was only a brief window where a power restored signal would maybe abort shutdown. Once the UPS monitoring program is terminated during shutdown there's no turning back. Nothing came of that. So now I buy only APC gear. They do the proper thing that if the AC power comes back after a shutdown command is issued the UPS will continue the shutdown sequence. And when the UPS shuts off it sees the power back on and restarts itself and the server comes back online. Other manufacturers may do it correctly and the one I dealt with might have clued in and fixed it but I'm not willing to gamble anymore.
