(Trained service technician only) Use this information to install the enclosure midplane.

About this task

disconnect all power
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.


  1. Connect the two fan cables to the enclosure and route the cables through cable clips.

  2. Install the midplane.
    1. ❶ Carefully align the enclosure midplane with the guide pins in the enclosure; then, slide the midplane into the enclosure.
      Do not grasp the connectors on the enclosure midplane when you install it in the enclosure. Touching the connectors might damage the connector pins.
    2. ❷ Fasten two screws on the top of the midplane.
    3. ❸ Connect the fan cables to the midplane.

After you finish

Reassemble the enclosure and program the vital product data (VPD) that is stored on the card. Complete the following steps:

Three trained technicians are required to complete the enclosure installation/removal task.
  • Two technicians must hold the front and rear handles at both sides of the enclosure.

  • One technician must protect the cables from damage.

  1. Carefully put the enclosure into the rack and slide the enclosure until rear handles are near front rack rails; then, remove rear handles at both sides.
