To remove the air baffle, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 40.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see “Turning off the server” on page 28).
3. Remove the cover (see “Removing the cover” on page 54).
4. Remove PCI riser-card assembly 1, if needed (see “Removing a PCI riser-card
assembly” on page 55).
5. Place your fingers under the front and back of the top of the air baffle; then, lift
the air baffle out of the server.
Attention: For proper cooling and airflow, replace all air baffles before you
turn on the server. Operating the server with any air baffle removed might
damage server components.
