Chapter 3 Maintaining the Server
Installing or Replacing Server Components
Replacing a GPU Card
Note The NVIDIA K80 GPU card requires a special conversion kit to be installed to this server. Use the
procedure in
Installing an NVIDIA K80 GPU Card and Conversion Kit, page 3-56 rather than the
procedure below.
Step 1 Shut down and power off the server as described in Shutting Down and Powering Off the Server,
page 3-9 .
Step 2
Slide the server out the front of the rack far enough so that you can remove the top cover. You might have
to detach cables from the rear panel to provide clearance.
Caution If you cannot safely view and access the component, remove the server from the rack.
Step 3 Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-10 .
Step 4
Remove the PCIe risers and any existing GPU card:
a. Lift straight up on both ends of the riser to disengage its circuit board from the socket on the
motherboard. Set the riser on an antistatic mat.
b.
On the bottom of the riser, loosen the single thumbscrew that holds the securing plate. See
Figure 3-26 .
c. Swing open the securing plate and remove it from the riser to provide access.
d.
Swing open the card-tab retainer that secures the back-panel tab of the card (see Figure 3-26 ).
e. Pull evenly on both ends of the GPU card to disengage it from the socket on the PCIe riser (or
remove a blanking panel) and then set the card aside.
Note See GPU Card Configuration Rules, page 3-52 before you install the GPU cards to the risers. Slot
population restrictions apply.
Step 5 Install your first GPU card into PCIe slot 2 or slot 5. See Figure 3-25 for the riser and slot locations.
Note GPU cards are not supported in PCIe riser 1 version 1B (UCSC-PCI-1B-240M4) or 1C
(UCSC-PCI-1C-240M4). Use riser 1 version 1A (slot 2) or riser 2 (slot 5) for GPU cards.
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 ).
c. Return the securing plate to the riser. Insert the two hinge-tabs into the two slots on the riser, and
then swing the securing plate closed.
d.
Tighten the single thumbscrew that holds the securing plate.
e. Close the card-tab retainer (see Figure 3-26 ).
f.
Position the PCIe riser over its socket on the motherboard and over its alignment features in the
chassis (see
Figure 3-24 ).
