  • Read Installation guidelines to ensure that you work safely.

  • Power off the server and disconnect all power cords for this task.

  • 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.


  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.
