Preparing for installation
When installing and removing the power supply, wear an ESD wrist strap and make sure the wrist
strap makes good skin contact.
在安装和拆卸电源模块时请注意佩戴防静电腕带，并确保防静电腕带与皮肤良好接触。
Before installing the power supply, make sure the operating voltage of the external power supply
system is as required by the power supply, and the output voltage of the power supply is as
required by the powered device.
在安装电源模块前，请确认外置供电系统的工作电压同电源模块所标电压、电源模块输出电压同受
电设备所需电压是否相符，避免对电源模块和受电设备造成损坏。
To avoid bodily injury, do not touch any bare wire or terminal.
不要接触露出的任何导线、端子部分，以免对人体造成伤害。
Never place the power supply in a wet area and prevent fluid from flowing into the power supply.
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。
To avoid damages, do not open the power supply. When an internal circuit or component of the
power supply fails, 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。
Before installing or removing the power supply, make sure no power cord is connected to it.
安装和拆卸电源模块时，应确保电源模块上没有连接电源线。
Safety recommendations 安全注意事项
1
Installingthepower supply 电源模块的安装
Verify that the power supply is compatible with the device before installing it. For more information,
see the installation guide for the device.
安装前请检查电源模块型号与设备是否匹配，具体请参见各产品的安装指导。
To prevent damage to the power supply or the connector on the backplane of the powered device,
insert the power supply gently.
为了避免损坏电源模块或受电设备背板的连接器端子，在电源模块插入过程中动作要缓慢。
If you insert the power supply upside down, you will encounter a hard resistance because of the
special structure designs of the slot and power supply. You must pull out the power supply, orient
it correctly, and insert it again.
如果上下倒置，安装过程将受插槽和电源模块特意设计的结构限制，不能顺利进行，必须先拔出模
块，然后重新插入。
If the captive screw cannot be tightly fastened, examine the installation of the power supply.
固定螺钉时，如果发现螺钉不能拧紧，很可能是因为电源模块没有正确安装引起的，请仔细检查。

①Wear an ESD wrist strap and make sure it 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。
②Unpack the power supply and verify that the power supply model is correct.
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。
③Correctly orient the power supply. Grasping the power supply handle with one hand and supporting
the power supply bottom with the other, insert the power supply slowly into the slot along the guide
rails. See callout 1 in the following figure.
保证电源模块上下方向正确，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，将电源
模块沿着电源插槽导轨水平插入，直到电源模块完全进入插槽，如下图①所示。
④Use a Phillips screwdriver to fasten the captive screws on the power supply to secure it in the chassis.
