System board installation movie

To remove the system board

  1. Disconnect the IDE cable for the disk drive, and the optical drive.
  2. Release the Ziff connector, and carefully remove the fragile diskette cable.
  3. Grasp the two small blue handles, and lift the board from the front while rotating the ports out of the cut-outs in the back of the chassis.
  4. Place the board assembly on the ESD mat.
    NOTE: When you order a system board with embedded security, use the part number in the hardware maintenance manual (HMM).
