Installing and removing the FRUs 模块的安装与拆卸
Before installing the fan tray, make sure the airflow direction marked on the fan tray meets the
ventilation requirement of the installation site.
安装风扇模块前，请根据风扇 模块的风向指示，确认气流方向和安装环境的通风要求一致。
The switch comes with the two fan tray slots empty. You must install two fan trays of the same
model on the switch. Do not power on the switch when no or only one fan tray is installed.
交换机出厂时两个风扇插槽均为空，为保证设备的正常散热，用户必须安装两个相同型号的风扇模
块，否则禁止交换机上电运行。
If both fan trays fail when the switch is operating, finish replacing the fan trays within 2 minutes.
交换机运行过程中，如果两个风扇模块均出现故障，则必须在2分钟内完成故障风扇模块的更换。
Connect the other end of the grounding cable to the grounding point on the rack.
接地线另一端连接到机柜接地点。
The switch provides front-to-back (port side to power module side) or back-to-front (power module
side to port side) airflow depending on the 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”两种通风走向，满足不
同环境下的散热要求。
Install the grounding cable before installing the switch to the rack.
为了防止机箱安装到机柜后无法安装接地线，因此请先将接地线安装到交换机的侧面接地点上。
Before installing cage nuts, mark their installation positions on the rack posts.
安装浮动螺母前，建议用户先使用记号笔在机柜立柱上标注浮动螺母安装位置。
