4.5 Removing and Installing Drives
The basic configuration of the computing unit includes a 3.5” floppy disk drive and
a 3.5” hard disk. An LS 120 drive is possible for custom solutions.
4.5.1 Removing and Installing the Hard Disk
The hard disk is used to store large quantities of data. It is installed on a
vibration-damped mounting that is easy to replace.
Caution
Danger of data being lost and the drive damaged
Drives are very sensitive to unacceptable vibrations. During operation, vibrations can
result in a loss of data or damage to the drive or a data medium.
If you wish to ship the device, wait until the drive has come to rest after you turn off
the device. (Approximately 20 s.)
1. Undo the 4 screws on the back of the system housing.
2. Swing open the drive cage.
3. Detach the drive cage from its mounting and place the drive cage face down on
the system housing.
4. Make a note of the cable assignment and detach the cables.
5. Proceed in the reverse order to install the new drive. The new drive must be of
the same type as the one removed.
