Safety precautions 安全注意事项
1
Installing the card 接口模块扩展卡的安装
Remove the filler panel (if any) from the target slot before installing the card. Keep the
removed screw and filler panel secure for future use. 如果交换机的接口模块扩展卡插
槽上装有假面板,请先将假面板拆除再进行接口模块扩展卡的安装,并请妥善保存拆卸
下的假面板以及固定该假面板的紧固螺钉以备将来使用。
2
Removing the card 接口模块扩展卡的拆卸
To avoid cable damage, remove the cables from the card before removing the card.
在拆卸接口模块扩展卡之前,推荐您先将接口模块扩展卡上的线缆拔出,以免在拆卸
过程中对线缆造成损坏。
If you are not to install a new card after removing the original one, install a filler panel
in the slot to prevent dust and ensure good ventilation in the device. 若接口模块扩
展卡拆卸完成后无须安装新的接口模块扩展卡,请您及时安装假面板,以保证设备的
良好通风散热并防止灰尘进入设备。
Place the removed card on an anti-static mat or in an anti-static bag. 请将拆卸下来的
接口模块扩展卡及时放置到防静电垫子上或防静电袋中。

①Unpack the card. Insert the card slowly into the
slot along the guide rails. 从包装袋中取出接
口模块扩展卡,并将接口模块扩展卡沿着插槽导
轨水平缓慢地推进接口模块扩展卡插槽。
②Rotate inward the ejector lever until the card is in
close contact with the switch. 将扳手用力向内
扣合,确保接口模块扩展卡和交换机紧密接触。
③Use a Phillips screwdriver to tighten the captive
screw on the card. 使用十字螺丝刀顺时针方向旋
转,拧紧接口模块扩展卡上的松不脱螺钉。
Before you install or remove the card, wear an ESD wrist strap and make sure the
strap makes good skin contact and is reliably grounded. 在安装和拆卸过程中,操作
者需自行准备并佩戴防静电腕带,请确保防静电腕带已经正确接地并与皮肤良好接触。
To avoid device damage, do not use excessive force when you install or remove the
card. 在安装和拆卸过程中,请不要用力过猛,以免对设备器件造成损坏。
