Step 14
Remove the PCIe riser from the server.
Note If you have only a single K80 GPU, it must be installed in PCIe riser 1A.
a. Grasp the top of the riser and lift straight up on both ends to disengage its circuit board from the
socket on the motherboard.
b. Set the riser on an antistatic surface.
c. On the bottom of the riser, loosen the single thumbscrew that holds the securing plate (see
Figure 3-26).
d. Swing open the securing plate and remove it from the riser to provide access.
e. Swing open the card-tab retainer (see Figure 3-26).
Step 15 Install your first K80 GPU card into PCIe riser 1A, slot 2. See Figure 3-25 for the riser and slot locations.
Note Observe the populations rules in GPU Card Configuration Rules, page 3-52. Use riser 1 version 1A
(UCSC-PCI-1A-240M4), slot 2 or riser 2 (slot 5) for GPU cards. GPU cards are not supported in PCIe
riser 1 version 1B (UCSC-PCI-1B-240M4) or 1C (UCSC-PCI-1C-240M4).
a. Align the GPU card with the socket on the riser, and then gently push the card’s edge connector into
the socket. Press evenly on both corners of the card to avoid damaging the connector.
b. Connect the GPU card power cable into the GPU card and into the GPU POWER connector on the
PCIe riser (see Figure 3-26).
Note The white connector on the cable connects to the GPU POWER connector on the riser; the black
connector on the cable connects to the GPU card.
c. Close the card-tab retainer (see Figure 3-26).
