②Remove the filler panel, if any, from the target power module slot. Keep the removed filler panel secure
for future use.
若准备安装电源模块的电源槽位上有电源假面板，则在安装电源模块前请先拆卸电源假面板。请善保管
电源模块插槽的假面板，以备将来需要时使用。
③Unpack the power module and verify that the power module model is as required. Keep the packaging
box and bag secure for future use.
从电源模块包装盒中取出电源模块，确认电源模块的型号与所需一致。请善保管电源模块的包装盒、包

④Correctly orient the power module. Holding the power module handle with one hand and supporting the
power module bottom with the other, slide the power power module along the guide rails into the slot
until you hear a click.
保证电源模块上下方向正确（电源模块及插槽为防反插结构设计，如果安装方向错误，电源模块将不能
完全插入到插槽中），用一只手握住电源模块上的拉手，另一只手托住电源模块底部，将其后端对准电
源插槽，将电源模块沿电源插槽水平插入插槽。当电源模块完全插入到插槽时，会听到电源模块上的锁
闩卡住插槽的声音。
Installing the power module 安装电源模块
To avoid bodily injury or device damage, follow the steps in the following figure to install the power

Safety guidelines 安全注意事项
To prevent device damage and bodily injury, follow these restrictions and guidelines when you install
or remove the power module:
为避免对电源模块和设备造成损坏及对人身的伤害，请遵从以下的注意事项：
Before you install a power module, make sure its airflow direction is as required.
在安装电源模块以前，请确认电源模块气流方向和安装环境的通风要求一致。
Do not install power modules that provide different directions of airflow on the same device.
不同风向的电源模块不要混插在同一台设备上。
Always wear an ESD wrist strap and make sure it makes good skin contact.
在安装和拆卸电源模块时，请佩戴防静电腕带，并确保防静电腕带与皮肤良好接触。
Before installing the power module, make sure the voltage of the power supply system is as
required by the power module, and the output voltage of the power module is as required by the
device.

设备所需电压一致。
Do not touch any bare cables or terminals of the power module.
请不要接触电源模块中露出的任何导线、端子部分。
Do not place the power module in a wet area, and prevent liquid from flowing into the power
module.
请不要将电源模块放置在潮湿的地方，也不要让液体进入电源模块内部。
To avoid power module damage, do not open the power module. When the internal circuits or
components of the power module fail, contact H3C Support.
为了防止电源模块受损，请不要随意打开电源模块外壳，当电源模块内部线路或元器件出现故障时，
请移交维修人员进行检修。

③Connect the other end of the power cord to the power supply system, and turn on the circuit breaker of
the power supply system.
将电源线的另一端插到外置交流供电系统或者外置高压直流供电系统的插座上，并连通电源输入端的断
路器。
④Examine the LED on the power module. If the LED is steady green, the power cord is successfully
connected. If the LED is off or red, examine the installation conditions, troubleshoot the problems, and
try again 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。
