If you are unable to get the nVidia Tesla card to function after installation or replacement, you may need to review this article.  This is most likely to occur on systems that are able to run multiple Tesla cards, such as the Precision T7500 and the T7400.  This may also affect you, if you are working with a single Tesla card and are having difficulty getting the card to function.

The Tesla cards have two power connectors: One six pin connector on the side of the card, and one eight pin connector at the end of the card.

There are three power configurations that are valid for a Tesla card to work properly.  This is indicated by a green LED on the card when powered up.

•          A single 8 pin power connection attached to the 8 pin connector.

•          Both connectors populated with a 6 pin connector and an 8 pin connector.

•          Both connectors populated with 6 pin connectors.

Any other configuration will produce a red LED on the card, and the card will not function.

In a system configured to run dual Tesla cards, one card will be using a single 8 pin connector, while the other will use the two 6 pin connectors to power both cards. 

If you are unable to complete the steps above or are still having issues with the power, you may need to contact technical support.  You can contact technical support via the link below.
