Follow these guidelines when you install or remove a fan tray:
在安装
/
拆卸风扇模块时，请注意如下事项：
Make sure the airflow direction of the fan tray is as required by the installation site.
请确认风扇模块气流方向和安装环境的通风要求一致。
The switch comes with the fan tray slots empty. Before powering on the switch, install a fan tray in
each fan tray slot and make sure the installed fan trays are the same model.
交换机出厂时风扇插槽均为空，为保证设备的正常散热，用户必须满配相同型号的风扇模块，
否则禁止交换机上电运行。
If more than one fan tray fails during switch operation, do not remove these fan trays
simultaneously. Replace one fan tray at a time and the replacement of each fan tray cannot take
more than three minutes.
在交换机运行过程中，如果有多个风扇模块出现故障，在更换风扇模块过程中禁止同时拔出多个风
扇模块，应按照拔出一个立即更换一个的方式进行，且单个风扇模块的更换时间不能超过
3
分钟。

交换机的风向设计
Make sure the air inlet and outlet vents are not blocked and the installation site has a good ventilation
system.
请确保交换机的进、出风孔不被遮挡，并将交换机安装在具有良好通风散热系统的环境中。
You can provide airflow for the switch from the port side to the power module side or from the power
module side to the port side by installing different fan trays.
通过配置不同的风扇模块，可提供“端口侧到电源侧”和“电源侧到端口侧”两种气流方向，满足不
同环境下的散热要求。
The LSPM1FANSA blow air from the power module side to the port side.
The LSPM1FANSB draw air from the port side to the power module side.
LSPM1FANSA
为吹风风扇，风向为电源侧进风，端口侧出风；
LSPM1FANSB
为抽风风扇，风向为端口侧进风，电源侧出风。

Available power modules vary by device model, but the installation and removal procedures are the
same. The following uses the PSR250-12A as an example. To remove a power module, first remove
the power cord.
各款交换机支持的电源模块不同，但安装与拆卸方式相似，此处以安装
PSR250-12A
电源模块为例示意。
For power modules available for the switch, see
H3C S6860 Switch Series Installation Guide
.
各款交换机支持的电源模块型号，请参见《
H3C S6860
系列以太网交换机 安装指导》。
Make sure the airflow direction of the power module is as required by the installation site.
Do not install power modules with different airflow directions on the same switch.
请确认电源模块气流方向和安装环境的通风要求一致。不同气流方向的电源模块不要混插在同一台交换
机上。

拆卸电源
To remove a DC power cord, you must first use a
screwdriver to loosen the captive screws on the power
cord connector.For a PSR450-12D power module, use
a flat-head screwdriver to loosen the captive screws
on the connector, and then remove the power cord
connector from the power module.
需要注意的是，在拆除
PSR450-12D
电源模块时，要先
拆除直流电源插头。
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。
