Mounting the switch to a rack 安装交换机到机柜
Introduction to installation accessories 安装附件介绍
Before installation, wear an ESD-preventive wrist strap, and make sure that the wrist strap
has a good skin contact and is well grounded. 在以下安装交换机的过程中，操作者需佩
戴防静电腕带，请确保防静电腕带已经正确接地并与皮肤良好接触。
When the depth of a switch is greater than 300 mm (11.81 in), the front mounting
brackets only secure the switch rather than bear its weight. 当交换机的深度大于300mm
时，前挂耳只对交换机起固定作用，不能用来承重。
The installation tools are not provided with the
switch. Prepare them by yourself.交换机不随机
提供安装工具，请用户根据实际安装需求自己
准备安装工具。

Connecting the power cable 连接电源线
Before connecting the power cable, connect the grounding cable and make sure that
the switch is correctly grounded. 在连接电源线前，需先连接保护地线，保证交换机正
确接地。
Connect the power cable to the switch first and then to the power supply system to
avoid bodily injury. 连接电源线时，请先完成电源线与交换机侧的连接，再进行电源线
与供电系统的连接，以免造成人身伤害。

You can use the external –48 VDC equipment-room power supply (with supplied –48
VDC power cable) or the RPS power supply recommended by H3C (optional RPS power
supply and power cable) for –36 VDC to –72 VDC input. You can use only the RPS
power supply recommended by H3C for RPS DC input. -36～-72V DC接口可以使用机
房-48V直流电（标配-48V直流电源线），也可以使用H3C推荐的外置RPS电源供电；
RPS DC接口必须使用H3C推荐的外置RPS电源供电（RPS电源及RPS电源线需选购）。
Installing the interface card 安装接口模块扩展卡
Do not touch the electronic components on an interface card to avoid damaging the
interface card. 请勿直接接触接口模块扩展卡上的元器件，避免造成损坏。
After removing an interface card, install a blank panel to the empty slot to prevent dust
from entering the switch. 若接口模块扩展卡拆卸完成后无须安装新的接口卡，请及时安
装假面板，以防止灰尘进入。
