Install the rear air baffle

Follow the instructions in this section to install the rear air baffle.

About this task

Attention

Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.
If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top covers, or remove the server from the rack. See Remove the server from rails.
If you intend to install memory modules in the server, you must first remove the air baffle from the server.
For proper cooling and airflow, reinstall the front and rear air baffles before you turn on the server. Operating the server with the air baffle removed might damage server components.

Procedure

Align the rear air baffle tabs with the rear air baffle slots on both sides of the chassis; then, lower the rear air baffle into the server.
Note
Close the retaining clip on each end of the memory module connector before installing the front air baffle for proper cooling.
