You may not need all the components in the kit for GPU installation. For information on riser configurations, see the expansion
card installation guidelines section.
Before you begin, follow the safefy guidelines and before working inside the system instructions.
1. Use the existing heat sink, cooling fans and air shroud.
NOTE: For more information about supported cooling fans matrix, see the thermal restriction section in Dell EMC
PowerEdge R750xa Technical Specifications on the product documentation page.
2. If required, install NVLink sponges and install NVLink bridges.
NOTE:
● Slot priority with NVLInk bridges: slot 33, slot 34, slot 31, and slot 32.
● Slot priority without NVLInk bridges: slot 31, slot 33, slot 34, and slot 32.
NOTE: GPUs that require NVLink sponges and bridges are NVIDIA A100 and NVIDIA RTX-A40.
3. If installing GPU other than T4 into front GPU riser module then, replace the GPU bracket.
4. If installing T4 GPU into front GPU riser module then, install the GPU riser module card holders.
5. Install the GPU into front GPU riser module or install the GPU into expansion card riser.
NOTE: Mixing of different GPUs are not allowed.
NOTE: See expansion card installation guidelines to know about risers and slots that support GPU.
NOTE: For information on riser slot location on the system board, see the System board jumpers and connectors topic.
6. If applicable, connect the power cables to the GPU. To know the connectors for GPU on the system board, see the System
board jumpers and connectors topic.
NOTE: Refer to the GPU power cable matrix to know about the requirement of cable for the GPU.
