NOTE: Ensure that you install the first GPU on riser
1.
NOTE: While installing a GPU on riser 3, place the GPU on the system with the GPU label side facing up.
Steps
1 Connect the GPU power cable to the connector on the system board.
NOTE:
While installing a GPU on riser 1, connect the GPU power cable to the connector on riser 1 and route the cable through the slot on
the GPU air shroud.
While installing a GPU on risers 2 or riser 3, connect the GPU power cable to the connector on the system board.
2 Connect the other end of the GPU power cable to the GPU.
3 Lift the expansion card latch and remove the filler bracket.
NOTE: You must install a filler bracket over an empty expansion card slot to maintain Federal Communications Commission
(FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and
airflow inside the system.
NOTE: The filler bracket is necessary to maintain proper thermal conditions.
4 Align the connector on the GPU with the connector on the riser.
5 Insert the GPU into the riser until it is fully seated.
6 Press the PCIe lock on the GPU air shroud and riser to release the PCIe card holder latch.
NOTE: Ensure that the GPU edges are seated properly in the GPU air shroud slot and PCIe card holder latch to secure the
GPU in place.
7 Close the expansion card latch.
