更换冷却风扇Replacing a cooling fan

使用以下过程更换冷却风扇。Use the following procedure to replace a cooling fan or fans.

先决条件Prerequisites

  1. 查看本指南开头的 注释、注意事项和警告Review Notes, cautions, and warnings at the beginning of this guide

  2. 查看处理预防措施。Review Handling precautions.

  3. 检查Review

    • 使用战术性云设备中的缩放单位节点时所需的知识Required knowledge for working with Scale Unit nodes in a Tactical Cloud Appliance

    • 如果使用的是硬件生命周期主机,则使用第5页上的硬件生命周期主机所需的知识Required knowledge for working with the Hardware Lifecycle Host on page 5 if you are working with the Hardware Lifecycle Host

  4. 完成Complete

    • 验证缩放单位节点的访问和运行状况(如果使用缩放单位节点)Verifying Scale Unit node access and health if you are working with a Scale Unit node

    • 验证硬件生命周期主机访问和运行状况(如果使用的是硬件生命周期主机)Verifying Hardware Lifecycle Host access and health if you are working with the Hardware Lifecycle Host

  5. 完成Complete

    • 如果使用缩放单位节点,请关闭缩放单位节点Powering off Scale Unit nodes if you are working with a Scale Unit node

    • 如果使用的是硬件生命周期主机,请关闭硬件生命周期主机Powering off the Hardware Lifecycle Host if you are working with the Hardware Lifecycle Host

步骤Steps

  1. 找到机架中的物理节点。Locate the physical node in the rack.

  2. 验证节点是否关闭。Verify that the node is powered off. 电源 LED 应为橙色。The power LED should be orange.

    注意

    在断开正在处理的服务器上的电缆之前,请确保每个电缆均已正确标记。Before disconnecting the cables on the server you are working on, ensure that each cable is properly labeled. 必须将电缆重新连接到相同的端口。The cables MUST be reconnected to the same ports.

  3. 更换风扇。Replace the fan or fans.

    遵循适用于缩放单元节点或硬件生命周期主机的 DELL EMC PowerEdge R640 安装和服务手册 中的风扇更换过程。Follow the fan replacement process in the Dell EMC PowerEdge R640 Installation and Service Manual for Scale Unit nodes or Hardware Lifecycle Hosts.

  4. 在节点上通电。Power on the node.

    重新连接电源后,如果服务器不会自动重新启动,则按下电源按钮打开节点。After reconnecting the power, if the server does not automatically reboot, then press the power button to turn the node back on.
