on page 29.
2. Make sure that the server and peripheral devices are turned off (see “Turning
off the server” on page 12) and that all power cords and external cables are
disconnected.
Attention: In a dc power environment, only trained service personnel other
than Lenovo 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 finger holes on the top of the air baffle.

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.
