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 and Safety inspection checklist to ensure that you work safely.

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

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

Procedure

  1. Make preparations for this task.
    1. Install all half-length PCIe adapters. See Install a HL PCIe adapter.
  2. Align the air duct with the studs on the fan cage at the same side as the installed A2/L4 GPU(s).
    Attention

    • The studs on the fan cage are positioned differently to align the corresponding A2/L4 GPU air duct(s).

  3. Insert the air duct onto the fan cage until it snaps into position.
