About this task

To avoid potential danger, make sure to read and follow the safety information.

  • 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

Procedure

  1. Make preparations for this task.
    1. Make sure that the power input board module is already installed in place (see Install a power input board (PIB) module).
  2. Connect the cables between the internal power supply unit and power input board (see Cable routing for the power module board and power input board module).
    Attention

    For a smooth installation, connect the cables between the power module board and power input board module BEFORE installing the power module board.

  3. Install the internal power supply unit and the cable wall.
    1. Align the internal power supply unit with the guide pins, lower and insert the internal power supply unit into place, and slightly press the touch point until it is securely seated; then, tighten the two screws by the sidewall of the node.
    2. Lower the cable wall into place on the internal power supply unit; then, tighten the two screws.
      Important
      • Make sure to place the pull tape of the power module board beneath the cable wall away from the DIMM slots. Otherwise, it may interfere with the memory modules and cause system failure.
      • Make sure that the busbars are seated in the holes of the power module board as shown in the illustration.
