GPU air baffle filler/Add-on air baffle Scenario
Figure 85. GPU air baffle filler
When the GPU air baffle is used, but a riser card is not 
installed with a GPU adapter, install this filler on the GPU 
air baffle.
Figure 86. Add-on GPU air baffle
If a single-wide FHFL GPU adapter is to be installed on 
slot 1, 4, or 7, but the adjacent slot (2, 5, or 8) is left empty 
or installed with a half-length adapter, install this add-on 
air baffle on the GPU air baffle first.
Note: If the adjacent slot (2, 5, or 8) is installed with a 
low-profile Ethernet adapter that use an active optical 
cable (AOC), the power of the AOC cable must be limited 
to 2.5 W or lower.

About this task
Attention: 
•  Read 
“Installation Guidelines” on page 47 and “Safety inspection checklist” on page 48 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” on page 62.
•  Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static- 
sensitive components in their static-protective packages until installation, and handling these devices with 
an electrostatic-discharge wrist strap or other grounding system.
•  Depending on the specific type, your GPU adapter might look different from the illustration in this topic.
Procedure
Step 1.  Make preparation for the task. 
a.  If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the 
top cover, or remove the server from the rack. See 
“Remove the server from rack” on page 63.
b.  Remove the top cover. See 
“Remove the top cover” on page 277.
Step 2.  Remove the riser assembly that has the GPU adapter installed. 
GPU adapter on riser 1 or 2 assembly
Note: The following uses riser 1 assembly as an example for illustration. The replacement 
procedure is the same for riser 2 assembly.
