A dedicated PCIe riser card is required for installing a GPU card. If the PCIe riser card to be installed is not dedicated for GPU cards, contact Huawei to deliver a dedicated card.

Procedure

Power off the server.
For details, see Power-Off Procedure.
Remove the cables from the PSUs.
For details, see Removing PSU Cables.
Remove the server.
For details, see Removing the Server.
Place the server on the ESD workstation.
Remove the chassis cover.
For details, see Removing the Chassis Cover.
Determine the slot and position of the PCIe card.
For details, see PCIe Slots.
Remove the PCIe riser module.
For details, see Removing a PCIe Riser Module.
Remove the PCIe card filler panel.

Perform this operation only when a filler panel is installed.

Figure 8-160 Removing a filler panel from I/O module 2 (example)
Take the spare part out of its ESD bag.
Install the PCIe card.
- Install the PCIe card on the PCIe riser module in I/O module 1 or 2.
  1. Insert the PCIe card into a PCIe slot. See (1) in Figure 8-161.
  2. Close the latch. See (2) in Figure 8-161.
  Figure 8-161 Installing a PCIe card in I/O module 2 (example)
- Install the PCIe card on the PCIe riser module in I/O module 3.
  1. Insert the PCIe card into the PCIe slot. See (1) in Figure 8-162.
  2. Close the latch. See (2) in Figure 8-162.

Connect the power cable to the PCIe card.

Certain models of PCIe CPU video cards must be connected with dedicated power cables. Connect the power cable to the GPU video card correctly. The silkscreen of the two power connectors on the mainboard for connecting GPU cables is J2 and J5.
- No power cable is used.
- Using a 6-pin power cable
  Connect the 6-pin connector on the GPU to an 8-pin connector on the riser card.
- Using an 8-pin power cable
  Connect the 8-pin connector on the GPU to an 8-pin connector on the riser card.
- Using an 8-pin (one-to-two) power cable
  Connect the 8-pin connector on the GPU to two 8-pin connectors on the riser card.

Power on the server.
For details, see Power-On Procedure.
Install the PCIe card driver.

If the PCIe GPU video card is replaced with a card of a new model, install the driver for the GPU card. For details, see NVIDIA GPU Card Driver Installation Guide.
Log in to the iBMC WebUI, and check whether the new component is normal.
