LED status 指示灯状态 Description 含义

Steady green 绿色常亮 The power module is operating correctly.电源模块工作正常

Flashing green

绿色闪烁

The power module has power input but is not installed in the device.

当前电源模块有电流输入（电源模块输入正常，但未安装到设备上，此时电

源模块的指示灯会绿色闪烁）

Steady red 红色常亮 The power module has failed or entered protection state.

电源模块出现故障或进入保护状态

Flashing red/green

alternatively

红色/绿色交替闪烁

The power module has generated an alarm for power problems (such as

output overcurrent, output overload, and overtemperature), but has not

entered protection state.电源模块告警（电源模块出现了如下情况，但还没

有进入保护状态：输出过流、输出功率过载、过温等）

Flashing red 红色闪烁

•The power module does not have power input. If two power modules

are installed and only one power module has power input, the status

LED of the power module that does not have power input flashes red.

当前电源模块没有电流输入（设备安装有两块电源模块，如果其中一块

电源有电流输入、另一块电源无电流输入，此时无电流输入的电源模

块的指示灯会红色闪烁）

•The power module is in input undervoltage protection state.

输入欠压保护

Off 灭The power module does not have power input.电源模块没有电流输入

①Turn off the circuit breaker for the power feed to the power module.断开电源输入端断路器。

②Wear an ESD wrist strap, and make sure the strap makes good skin contact and is reliably grounded.

佩戴防静电腕带，请确保防静电腕带与皮肤良好接触，并确认防静电腕带已经良好接地。

③Loosen the removable cable tie, and remove the power cord connector from the power module.

松开固定电源线的可拆卸式扎带，取下电源线。

Turn off the circuit breaker

断开电源输入端断路器 Remove the power cord

拆除电源线 Remove the power module

拆卸电源模块

To avoid bodily injury or device damage, follow the steps in the following figure to remove the power

module. 电源模块的拆卸过程应严格按照下图顺序进行，否则可能会对设备造成损坏或对人身造成伤害。

Removing the power module拆卸电源模块

②Connect the other end of the power cord to an AC or DC power source, and then turn on the circuit

breaker. 将电源线的另一端插到外置交流或直流供电系统的插座上，并连通电源输入端的断路器。

③Examine the LED on the power module. If the LED is steady green, the power cord is connected

correctly. If the LED is off or red, examine the installation and troubleshoot the problems until the LED

becomes steady green.查看电源模块的状态指示灯，如果指示灯的状态为绿色常亮，说明电源线连接成

功。如果指示灯不亮或为红色，请仔细检查安装情况，排除各种故障后，再次尝试，直到电源模块状态指

示灯正常为止。

PSR450-12D power module PSR450-12D电源模块

For a PSR450-12D power module, use a flat-head screwdriver to loosen the screws on the protection

cover over the power receptacle and then remove the cover. Connect the female connector of the

power cord to the power receptacle on the power module, and then fasten the screws on the

connector.

连接PSR450-12D电源模块的电源线时，先用一字螺丝刀逆时针旋松直流电源连接器保护盖两侧的固定

螺钉，并取下连接器的保护盖，再将电源线插头插入到电源模块的直流输入插口上，用一字螺丝刀顺时

针方向拧紧直流电源线插头两侧自带的螺钉，使电源线插头固定在电源模块直流输入插口上。

To prevent the power cord from falling off, use a removable cable tie to secure the power cord to the

power module handle. For the securing method, see "PSR450-12A/PSR450-12A1 power module."

为防止电源线脱落，请使用可拆卸式扎带将电源线固定到电源模块的拉手处，固定方法同PSR450-

12A/PSR450-12A1电源模块。

④Hold the handle of the power module with one hand, press the latch on the power module to the right

with your thumb, and pull the power module part way out of the slot. Supporting the power module

bottom with one hand, slowly pull the power module out of the slot along the guide rails with the other.

一只手握住电源模块上的拉手，用拇指向拉手侧掰动锁闩，同时向外垂直拉动电源模块，将模块拉出来

一部分后，用另一只手托住电源模块底部，将电源模块缓慢拉出。

⑤Put the removed power module on an antistatic mat or in its initial package.

将拆卸下来的电源模块放置到防静电垫子上或电源模块的包装袋中。

If you are not to install a power module in the slot,

install a filler panel in the slot to prevent dust from

entering the chassis. 如果该电源插槽中不再安装

电源模块，请将电源模块插槽的假面板安装到该插

槽上，以免灰尘进入机箱。

For a PSR450-12D power module, use a flat-head screwdriver

to loosen the screws on the connector, and then remove the

power cord connector from the power module.PSR450-12D电

源模块需要先使用一字螺丝刀逆时针拧下直流电源线插头两侧

自带的螺钉，然后将插头向外拔出。

For a PSR450-12AHD power module, release the jaw of the cable clamp and open the cable clamp, and

then remove the power cord connector from the power module. PSR450-12AHD电源模块需要先解开防脱

线扣上的卡扣，然后松开电源线缆上的防脱线扣，最后向外拔出电源线插头。
