Figure 15. Air baffle installation

Step 1.  Align the air baffle pins with the pin holes on both sides of the chassis; then, lower the air baffle into 

the compute node. Press the air baffle down until it is securely seated. 

Note: 

Close the retaining clip on each end of the DIMM connector before installing the air baffle.

After you install the air baffle, complete the following steps: 

1.  Install the compute node cover (see “Install the compute node cover” on page 43 ).

2.  Install the compute node into the chassis (see “Install the compute node in the chassis” on page 25 ).

3.  Power on the compute node.
