shock hazard
Hazardous voltage, current, and energy levels might be present. Only a qualified service technician is authorized to remove the covers where the label is attached.
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

Operating the server with the top cover removed might damage server components. For proper cooling and airflow, install the top cover before you turn on the server.

A new top cover comes without a service label attached. If you need a service label, order it together with the new top cover and attach the service label to the new top cover first.


  1. Check your server and ensure that:
    • All cables, adapters, and other components are installed and seated correctly and that you have not left loose tools or parts inside the server.

    • All internal cables are connected and routed correctly. See Internal cable routing.

  2. Install the top cover to your server.
    Handle the top cover carefully. Dropping the top cover with the cover latch open might damage the cover latch.

    2. Press down the cover latch and ensure that the cover latch is completely closed.
    3. Use a screwdriver to turn the cover lock to the locked position.
