GPU Card Installation Guidelines

Observe the following guidelines while installing a GPU card:

•Ensure that the GPU cable is available.

•Ensure that all GPU cards are of the same type or model.

•Your system supports only Q4000 single-width GPU cards and Q6000 double-width GPU card.

•The two-processor configuration supports one double-width or two single-width cards on slots 3 and 5.

•For systems with a single GPU card, connect the GPU card power cable to the GPU power connector CN11 on the power distribution board.

•For systems with two GPU cards, connect the first GPU card power cable to the GPU power connector CN11 on the power distribution board and the second GPU card power cable to the GPU_POWER connector on the power interposer board.

•Systems with a double-width GPU card can support only one 5.25 inch removable media storage device.

•GPU cards must be installed on a system with redundant 1100 W AC power supplies.
