服务器中的电源供应器出现故障。服务器管理口出现power supply failure可能是由于长时间使用、环境温度高、电源负载过高等原因导致电源故障，就会导致服务器无法正常运行。出现这种情况需要尽快更换电源供应器以恢复服务器的功效。 当检测到主板有电压跌落，或异常掉电时，也可能会产生power supply failure告警，此时服务器自动关机，导致操作系统业务中断。

直流电源的意思

dc power supply直流电源例句:1.It combines servers, storage, networking, ups and dc power distribution in one unit. 每个设备单元包含服务器，数据存储，网络ups以及直流供电系统。 2.It will hold six batteries for power storage and will use a 120v dc power distributionsystem, compared to apollo"s three-battery storage and 28v dc system. 与阿波罗的3个电池储备和28伏的直流系统相比，猎户飞船将有6个电池的电力储存，使用120伏的直流电源分配系统。

这个是 开关电源的意思

华硕主板的电涌保护功能，这个自己没太好办法检测，只能硬件替换。或者将其关闭。提示中写的“ASUS Anti-surge ”没有，就是这个东西在搞鬼，把它关掉就OK了。具体操作方法：在开机时按F1或者在提示时按F1进入BIOS设置，选择POWER选项，把Anti surge Support改成Disable，再按F10保存退出就OK了

power supply is not present.这句话的意思是，一般需要用到电源适配器供电的产品，但在销售的包装中没有配电源适配器，需要购买者自己配备合适的电源适配器。

EPS英文全称为EmergencyPowerSupply（紧急电力供给），是当今重要建筑物中，为了应急照明、事故照明、消防设施而采用的一种应急电源。它主要由输入单元、输出单元、充电模块、电池组、逆变器、监控器、输出切换装置等部分组成，该系统能够在应急状态下提供紧急供电。广泛适用于市电中断时各类一级和特别重要负荷的交流应急供电，如各类重要计算机系统的供电；各类建筑的工作供电和消防供电；医院安全供电；交通系统高速公路、隧道、地铁、轻轨、民用机场的供电；电力系统的供电；各类不能断电的生产、实验设备的供电。

电脑主板上PWR是PowerSupply（电源）的缩写，电脑主板上BTN是Power Button的缩写，Power Button的中文意思是电源按钮，其作用为接机箱上的电源的。电源开关为两个插脚，可能的标注有Power SW，PW，PWR，PWRBTN，POWER，ON/OFF等，在不连接机箱的情况下短接两个插脚也可以起到开机键的作用，就是很多人使用导电的物体同时触碰两个触角，就能形成短接，非常简单。如果power button被触发，这个信号会引起SMI或者SCI来表示系统请求进入到睡眠状态。如果系统已经处于睡眠状态，这将导致唤醒事件信号。如果PWRBTN键超过4秒，这将导致一个无条件的过渡（电源按钮替代）到S5状态。即使系统是在S1-S4的状态，覆盖也会发生。这个信号有一个内部上拉的输入电阻和内部有一个16毫秒的反弹。扩展资料：电脑主板其他接口含义重启开关也是两个插脚，可能的标注包括RESET SW，RESET，RES，RST等，在不连接机箱的情况下短接两个插脚也可以起到重启键的作用。电源指示灯的标注多为PLED或PWR_LED；硬盘指示灯的标注多为HDLED或HD。F_USB指的是前置USB接口，F即front的缩写。同样，F_AUDIO指的是前置音频接口，和机箱的设计相同，F_USB 3.0的蓝色19针插座是前置USB 3.0接口。此外还有SPEAKER或SPK，指的是主板的工作报警器，IR/CIR表示红外接口，J_PRINT为打印机接口，J_COM为COM接口。参考资料来源：中关村在线—这些装机跳线的小技巧一般人我不告诉他

新配的电脑开机提示Power supply surges detected during the previous power on ASUS Anti-surge的解决步骤如下：1、开机后开始出现问题画面，根据提示按F1进入bios。2、将主板bios的设置语言改成“简体中文”。3、根据画面提示，进入高级模式选项。4、然后移动到监控选项，在下面可以看到电涌保护功能是打开的。选择关闭，保存设置。再重启，即可解决问题。

power supply 英文开关电源的意思，和品牌没有任何关系，我们生产的开关电源，外箱都有这个标志

这两根线其实就是同一根线啦，同学PWR BTN是Power Button的缩写PWR SW是Power Switch的缩写都是指同一样东西，两个接一起就万事大吉了

电力供应electrical power 电力，电能supply 名词，供应，供给的意思

没接上用电器 可能是线路哪里断路

要开。首先把C站设备的POWERSUPPLYUNIT的电源开启，过10秒后，同时把IME设备、打印机的电源打开，IME设备的同步、入网、调谐的指示灯会相继亮起，不开启powersupplyunit电源什么都做不了。powersupplyunit翻译供电机组，供电设备，电源部件。“电源设备(PowerSupplyUnit)”是稳压器的电源。服务器、台式机和笔记本电脑的电源通常是12V，移动设备的电源是3.3V。

the power supply电力供给，电站

1.电源2.输入信号3.接地（通用型）4.监控输出

译作：未检测到515号电源的冷却风。1、常见于某些设备的中控报警中，就本例而言，指515号电源的冷却风风压检测元件没有正常发出高（或低）电平信号，从而被系统程序判定为故障。2、如果该电源的冷却风供应正常，更换同型号的风压检测元件即可。3、Power Supply 即：供应电源，通常简写为“电源”，前面的数字为其工作（或设计）编号。

dc power supply直流电源例句:1.It combines servers, storage, networking, ups and dc power distribution in one unit. 每个设备单元包含服务器，数据存储，网络ups以及直流供电系统。2.It will hold six batteries for power storage and will use a 120v dc power distributionsystem, compared to apollo"s three-battery storage and 28v dc system. 与阿波罗的3个电池储备和28伏的直流系统相比，猎户飞船将有6个电池的电力储存，使用120伏的直流电源分配系统。

开关电源是一大类，通常我们说的开关电源是指交流变直流的电源，但其实也包括直流变直流，直流变交流（逆变）都应该是属于开关电源。简单的说，开关电源是通过控制开关器件（例如MOS管，IBGT管）的通断时间（占空比）来达到控制输出电压或者输出电流的目的。例如一个AC／DC开关电源就要经过AC－整流—滤波—高频开关－高频交流－高频整流－滤波－输出稳定的直流这样一个过程，其中采用闭环控制来达到输出稳定。而电子式开关只是一个开关而已，控制电路的通断，就像代替普通的手动开关一样。给电子开关一个开通信号，线路接通，断开控制信号或者给一个关断信号，电子开关截止。电子开关与普通开关不同处在于它是无触点式的。所以避免诸如手动开关按钮及接触器之灯的在开通和分断时的火花损耗和机械噪音等。而且控制功率小控制方便。在开关电源中的起开关作用的诸如MOS管和IGBT之类的都属于电子开关，可控硅也属于电子开关。而我们通常所提的电子开关是指市场上的固态继电器等，它也是用可控硅的原理制作的。

①、电路中的导线的漏电导致的漏电保护开关的处理措施。这时我们首先要看一下漏电保护开关上面的复位按钮是否弹出。如果弹出，就确定是漏电。然后在确保整个回路中没有负载。也就是说，我们的电器是正常的，那么这时就需要检查电路。其实检查电路就是使用摇表来摇测导线的绝缘电阻值。像家用电线的绝缘电阻值，一般不能够小于0.5MΩ。这样逐一进行检测，以此来判断导线的绝缘值情况，从而找到漏电的部位。②、回路下口所负载的电器存在漏电所导致的漏电保开关跳闸的处理措施。其实这个时候我们只可以换一台电器来进行检测。做法就是我们把原来这台电器先不用，使用其他电器来进行实验。如果这时不在跳闸，那么就可能就判断我们的电器有问题。这时个人给出的处理建议就是，找对应的电器的维修人员来给我们检查。因为这时需要拆开电器来检测电器内部的绝缘电阻情况。其实像这种情况，出现在一些老房子中的几率非常的高。③、过载导致的漏电保护开关跳闸的处理措施。由于过载就是我们家中用的电器太多了，或者是某台电器的功率过大，那么这时首先我们要把家里功率特别大的电器关掉，然后去观察一下是否还跳闸。如果此时不再跳闸，就说明我们这台电器在我们家中不能够正常使用。像目前比较常见的即热式电热水器，其实在很多家庭中都是不能使用的，它的功率已经远远超过了我们室内的用电总负荷。个人的观点就是像单台电器的功率如果超过6kw，都不建议大家在家庭中使用，否则一般都会出现过载的情况。④、短路导致的漏电保护开关跳闸的处理措施。其实短路在跳闸的时候，声音非常明显，是嘭的一声儿，不像漏电时的跳闸，啪的一声。另外，短路跳闸以后，如果合闸，是合不上的，会立即出现跳闸的情况。检查短路的方法非常简单，我们就使用万用表的通断档来测量导线。如果导线与导线之间发出蜂鸣声，也就说明这两个导线之间是连通的，那么就说明我们的电源在某个位置是处于了短路的状态。以此来对我们家中的电路和电器进行检查就可以了。
