To remove the DIMM air baffle, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 28.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see “Turning off the server” on page 13).
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. Remove the riser-card assembly (see “Removing the riser-card assembly” on
page 32).
5. Place your fingers into the handle and opening on the top of the air baffle.
6. Press the handle toward the opening and lift the air baffle out of 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.
