3.   Installing the power supply 

安装电源模块

 

 

 

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 need to 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。

 

 

Before installing the power supply on a switch, make sure it matches the 
switch model. For more information, see the installation guide for the 
switch. 

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。

 

 

Keep the filler panel, packaging box, and packaging bags for the power 
supply secure for future use. 

请妥善保管假面板及电源模块的包装盒、包

装袋等物品,以备将来需要时使用。

 

 

(1)  Unpack the power supply and verify that the input mode of the power supply is 

as required. 

从电源模块包装盒中取出电源模块,确认电源模块的输入方式与

所需一致。
