Installing the mounting brackets and short slide rails 挂耳与短滑道配合安装
2
If the rack depth is in the range of 401 to 692 mm (15.79 to 27.24 in), purchase long chassis rails and
short slide rails yourself for installation. You need to install the long chassis rails as follows based on
the rack depth:
Not reaching out of the chassis for a rack with the depth in the range of 401 to 498 mm
(15.79 to 19.61 in).
Not reaching out or reaching out of the chassis for a rack with a depth in the range of 499 To
565 mm (19.66 to 22.24 in).
Reaching out of the chassis for a rack with the depth in the range of 566 to 692 mm
(22.28 to 27.24 in).
如果机柜前后方孔条间距在401～692mm范围内，请使用选配的短滑道长导轨配合安装。因短滑道配
套的长导轨有正装（导轨不会超出设备）和反装（导轨会超出设备）之分，用户可以根据机柜方孔条
之间的距离灵活选择安装方式。
当机柜前后方孔条间距在401～498mm范围内，请使用长导轨正装方式安装。
当机柜前后方孔条间距在499～565mm范围内，长导轨正装和反装都可以。
当机柜前后方孔条间距在566～692mm范围内，请使用长导轨反装方式安装。
For device stability, make sure the slide rails slide a minimum length of 90 mm (3.54) into the chassis
rails when rack-mounting the switch.
为保证设备安装后的稳定性，当滑道与滑道导轨安装完成后，请确保滑道的头部进入滑道导轨的最小
深度为90mm。
Mounting brackets installed near the port side 挂耳安装在靠近端口侧
Install the chassis rails at a or b. The chassis rails can be installed reaching out of the chassis or
not reaching out of the chassis. 挂耳安装在靠近端口侧时，滑道导轨可安装在a或b任意一处，可采
用正装方式，也可采用反装方式。

Mounting brackets installed near the power module side 挂耳安装在靠近电源侧
Install the chassis rails at c or d. The chassis rails can be installed reaching out of the chassis or not
reaching out of the chassis.
挂耳安装在靠近电源侧时，滑道导轨可安装在c或d任意一处，可采用正装方式，也可采用反装方式。
Connect the grounding cable to a grounding point before installing the switch in the rack.
为了防止机箱安装到机柜后无法安装接地线，请先将接地线安装到交换机侧面的接地点上。
The switch provides a grounding sign at the primary grounding point but not at the auxiliary
grounding point.
交换机主接地点标有接地标识，备用接地点上无接地标识。
The grounding screws provided with the switch are applicable to both the primary and auxiliary
grounding points.
交换机随机附带的接地螺钉同时适用于主接地点和备用接地点。
Installing the switch in a 19-inch rack 安装交换机到19英寸机柜
The installation procedure is the same for using long and short chassis rails. The following procedure
uses the short chassis rails as an example.
采用长滑道短导轨安装交换机到机柜与采用短滑道长导轨安装交换机到机柜的方式相同，本文以采用
长滑道短导轨安装交换机到机柜为例。
Install cage nuts and slide rails 安装浮动螺母与滑道

Before installing cage nuts, mark their installation positions on rack posts.
安装浮动螺母前，建议用户先使用记号笔在机柜方孔条上标注浮动螺母安装位置。
