我在 Ubuntu 16.04 服务器上安装了 Nut,以便与我的 Eaton 5SC-750 进行连接,如下所示本指南。但是,当我从墙上拔下 UPS 时,服务器立即关闭,并且控制台上不显示任何消息。
我觉得这是发出了强制关机命令,而不是执行指南提供的脚本。为什么?我该如何修复它?
我希望它能用电池运行 2 分钟,然后再关机。我计划将第二台服务器(作为 Nut 中的从属服务器)连接到此 UPS。
以下是切换至电池关机的系统日志条目:

这个问题已经存在三年多了,但对于遇到同样问题的人来说:您是否检查过您的 UPS 是否有一个或多个输出没有电池备份?就我而言,我设法为 NUT 服务器选择了具有浪涌保护的单个插座,当模拟断电时,它当然会立即关闭,而从属电源保持开启状态。找出原因并更换插头后,一切都正常了。
