 如果想了解设备的使用功率的详细情况，可以查看功率信息。当系统扩容时，可以先确认电源功率是否足够。
<Huawei>display power system7、查看单板电压
 当设备单板的电压异常时，用户可以执行以下命令查看单板电压的状态信息。
<Huawei>display voltage { all | slot slot-id }8、查看温度信息
 设备温度过高或过低可能会导致硬件的损坏。如果想了解设备的当前温度值，可以执行以下命令查看温度信息。
<Huawei>display temperature { all | slot slot-id }9、查看风扇状态
 风扇的正常运转是保证设备正常工作的前提。设备散热不正常会引起设备温度升高，并可能损坏硬件。
<Huawei>display fan ?

 <cr> 
<Huawei>display fan-para { all | slot slot-id } # 查看风扇额定功率和调速策略10、查看CPU占用率
 CPU占用率是衡量设备性能的重要指标之一。在网络运行中，CPU占用率过高常常会导致业务异常，例如BGP震荡、VRRP频繁切换甚至设备无法登录。
 执行以下命令，可以实时查看CPU占用率的统计信息和配置信息，以保证设备能够运行在稳定状态。
 通过查看CPU占用率的配置信息，可以查看当前CPU占用率的监控告警过载阈值和监控告警恢复阈值。当CPU占用率上升到监控告警过载阈值时，系统触发监控过载告警。当CPU占用率下降到监控告警恢复阈值时，系统触发监控恢复告警。

<Huawei> 11、查看内存占用率
 内存占用率是衡量设备性能的重要指标之一。在网络运行中，内存占用率过高常常会导致业务异常。实时查看内存占用率信息，以确认设备是否运行稳定。
 通过查看内存占用率门限值，可以查看监控告警触发条件。当内存占用率上升到门限值时，系统触发告警。当内存占用率低于门限值时，系统告警消除。
