Removing the cover

Use this information to remove the cover.

Read the safety information in Safety and Installation guidelines.

If you are replacing a server component or an optional device in the server, you need to turn off the server and peripheral devices, and disconnect the power cords and all external cables.

Before you install optional hardware, make sure that the server is working correctly. Start the server, and make sure that the operating system starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly.

To remove the server cover, complete the following steps.

  1. Read the safety information that begins in the begin of this documentation.
  2. Turn off the server and peripheral devices and disconnect the power cords and all external cables, if necessary.
  3. If the server has been installed in a rack, loosen the two thumbscrews on the front of the server and remove the server out of the rack enclosure; then, place it on a flat, static-protective surface.
    When you disconnect the power source from the server, you lose the ability to view the LEDs because the LEDs are not lit when the power source is removed. Before you disconnect the power source, make a note of which LEDs are lit, including the LEDs that are lit on the front panel, on the rear panel, and LEDs inside the server on the system board, then, see this documentation for information about how to solve the problem.
  4. Press down firmly on the blue tab on the top of the cover (on the right side near the front of the server) and slide the cover toward the rear of the server until the cover has disengaged from the chassis.

  5. Lift the cover off the server and set it aside.
    For proper cooling and airflow, replace the server cover before you turn on the server.
