Step 1.  Make sure the expansion tray air baffle is installed on the system board. If not, install it. 

Attention:

Air baffle is required for airflow that creates proper cooling. Make sure to install proper 

air baffles for system configuration before the power is turned on.

Figure 110. Installing the expansion tray air baffle

Step 2.  Align the processor and memory expansion tray with the two pairs of guides on the sides, and 

lower it into the chassis.
