当节点 2 已接管配对节点 1 进行硬件维护时，可以看到以下错误和节点 2 的系统关闭：

Mon Jun 05 19:09:58 -0400 [node2: env_mgr: monitor.chassisPowerSupply.degraded:notice]: Chassis power supply 1 is degraded: PSU1 InPower is Warning High (1000 W) Mon Jun 05 19:09:59 -0400 [node2: power_low_monitor: monitor.chassisPower.degraded:alert]: Chassis power is degraded: Power Supply Status Critical: PSU1 FRU.

Mon Jun 05 19:11:28 -0400 [node2: env_mgr: monitor.chassisPowerSupply.degraded:notice]: Chassis power supply 1 is degraded: PSU1 InPower is Critical High (1020 W)

在此期间，在节点 2 的 BMC 事件日志中可以看到以下内容：
