Installing Expansion-Card Risers
CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
1. If applicable, reinstall the expansion card(s) into the expansion card riser.
2. Align the expansion-card riser with the connector and the riser guide pin on the system board.
3. Lower the expansion-card riser into place until the expansion-card riser is fully seated in the connector.
4. Close the system.
5. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
6. Install any device drivers required for the card as described in the documentation for the card.
GPU Card Installation Guidelines
NOTE: Internal GPU cards are supported on the PowerEdge R720 and not on the PowerEdge R720xd.
NOTE: Due to the high power consumption of GPUs, the ambient system inlet temperature is restricted to 30 °C to
ensure adequate system cooling when one or more GPU cards are installed in PowerEdge R720. Note that this is
less than the standard environmental specification of 35 °C.
• The PowerEdge R720 must be installed with two processors.
• The processor must be of 115 W or less.
• The processor must use a GPU kit low-profile heat sink.
• Ensure the GPU enablement kit is available.
GPU enablement kit includes:
