Dell EMC PowerEdge R740xd Installation and Service Manual

GPU or ACLR card installation guidelines

Ensure that both the processors are installed.
The processor must use a GPU kit low-profile heat sink module.
To ensure adequate cooling when one or more GPUs are installed, the ambient inlet temperature is restricted to 30°C for CPU 150 W/8 C, 165 W/12 C, 200 W, 205 W. For more information, see the www.dell.com/poweredgemanuals section.
Ensure that the GPU enablement kit is available.
The GPU enablement kit includes:
- GPU air shroud
- Mylar
- Riser 3A or 3B
- GPU cable for riser 3A or 3B
- GPU cable for riser 2A or 2E or 2D or 2F
- Riser 2A or 2E or 2D or 2F
- Riser 1A or 1D
- GPU cable for riser 1A or 1D
- Two 1U processor and heat sink modules and two CPU clips
- Six high performance cooling fans
All GPUs must be of the same type and model.
You can install up to three double-wide or six single-wide GPUs.
The filler bracket on the GPU air shroud must be removed before installing the GPU.
Ensure that high-performance fans, and GPU air shroud are installed.

NOTE: When using systems with GPU, ensure that you install PSUs with 1100 W or higher, and set the PSU configuration to non-redundant mode.

NOTE:Generally, any GPU that is greater than 75 W requires a power cable. GPUs with 75 W or less does not require a power cable.
