Install an A2/L4 GPU air duct

Follow the instructions in this section to install an A2/L4 GPU air duct.

About this task

S002
disconnect all power
CAUTION
The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
Attention

  • Read Installation guidelines to ensure that you work safely.

  • Power off the server and disconnect all power cords for this task.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

  • When one or more A2/L4 GPUs are installed between PCIe slots 1 and 4 or between PCIe slots 5 and 8, one or two A2/L4 GPU air ducts are required to be installed on the fan cage at the same side as the installed A2/L4 GPU for proper cooling and airflow.

  • See Technical rules for GPU for detailed information about the technical rules for GPU installation.

Procedure

  1. Align the A2/L4 GPU air duct with the studs on the fan cage corresponding to the installed A2/L4 GPU.
    Attention

    • An A2/L4 GPU air duct is required to be installed in the same air zone as an installed A2/L4 GPU.

    • The studs on the fan cage are positioned differently for different A2/L4 GPU air ducts.

  2. Insert the A2/L4 GPU air duct onto the fan cage until it snaps into position.
