Installing the microprocessor 2 air baffle
To install the microprocessor 2 air baffle, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 38.
2. Make sure that the server and peripheral devices are turned off (see “Turning
off the server” on page 22) and that all power cords and external cables are
disconnected.
3. Remove the cover (see “Removing the cover” on page 44).
4. Align the tab on the left side of the microprocessor 2 air baffle with the slot in
the right side of the power-supply cage.
5. Lower the microprocessor 2 air baffle into the server. Make sure that the pin on
the end of the air baffle is inserted into the hole on the system board (see the
illustration).
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.
