Moving The Computer

Take the following precautions before moving the Type 2179 or Type 6643 computer.

1.Remove all media from the drives.

2.Power-off the computer and all attached devices. The hard disk drive automatically parks the read/write heads to prevent damage to the hard disk.

3.Unplug the power cords from the electrical outlets.

4.Disconnect the communication, modem, and/or network cables from their outlets first, then from the computer.

5.Disconnect all attached device cables from the computer.

6.If you are moving the computer a short distance, you can carry the keyboard on the computer base.
