Installing the microprocessor air baffle Microprocessor air baffle Finger holes To install the microprocessor air baffle, complete the following steps: 1. Read the safety information that begins on page vii and "Installation guidelines" on page 28. 2. Make sure that the server and peripheral devices are turned off (see "Turning off the server" on page 13) and that all power cords and external cables are disconnected. Attention: In a dc power environment, only trained service personnel other than IBM service technicians are authorized to connect or disconnect power to the dc power supply. See the documentation that comes with each dc power supply. 3. Remove the cover (see "Removing the cover" on page 31). 4. Place your fingers into the two openings on the top of the air baffle. 5. Align the tab on the left side of the air baffle with the slot in the left side of the chassis. 6. Lower the air baffle into the server. Attention: For proper cooling and airflow, replace the air baffle before you turn on the server. Operating the server with an air baffle removed might damage server components. Chapter 2.
