Install a GPU adapter link bridge
Follow instructions in this section to install a GPU adapter link bridge.
About this task
Attention
- Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
- Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.
- Depending on the specific type, the GPU adapter might look slightly different from the illustrations in this section.
- Follow the additional instructions in any documentation that comes with your GPU adapter.
Depending on the configuration, select the corresponding installation procedures:
AMD 4-slot link bridge
Procedure
Note
Install the GPU adapter link bridge to connect the GPU adapters listed below:
- GPU 1, GPU 2, GPU 3, and GPU 4
- GPU 5, GPU 6, GPU 7, and GPU 8
- Align the guide pins on the GPU adapter link bridge with the guide holes on the GPU adapters; then, gently place the link bridge onto the GPU adapters.Figure 1. GPU adapter link bridge installation
- Fasten the eight screws in the sequence shown in the illustration below.Figure 2. Screw tightening sequence
NVIDIA 2-slot link bridge
Procedure
Note
Install the GPU adapter link bridge to connect the GPU pairs listed below:
- GPU 1 and GPU 2
- GPU 3 and GPU 4
- GPU 5 and GPU 6
- GPU 7 and GPU 8
- Remove the link connector cover from the GPU adapter.Figure 3. Link connector cover removal
- Align the GPU adapter link bridge to the link connectors on the GPU adapters; then, install the GPU adapter link bridge to the GPU adapters until it clicks into place.NoteDepending on the configuration, there may be one or three GPU adapter link bridges on the GPU adapter. When linking a GPU pair, all link connectors on the GPU adapters must be linked.Figure 4. GPU adapter link bridge installation
