Emergency eject
The following procedure is used to remove the data medium when the eject button
is locked by software or no power is being supplied to the drive. Motor-driven
opening is not possible in this case.
1. Make sure that there is no power supply to the drive (switch off the PC).
2. Insert a max.1.3 mm thick and at least 55 mm long object (for example an
elongated paper clip) into the emergency removal hole at the front of the drive.
Careful pressure opens the drive tray and pushes the data medium out of the drive.
Pull the CD tray manually further out of the housing and remove the CD.
At least 55 mm (2.1654”) long

3.6.2 Floppy Disk or LS120 Drive (Depending on Hardware
Configuration)
With the floppy disk drive, you can save programs and data to floppy disk and load
them from disks onto the computing unit.
As an alternative to a floppy disk drive, the computing unit can be equipped with an
LS 120 drive for custom solutions.
Floppy disk types
You can use the following floppy disks with the floppy disk drive:
Double Sided High Density, 3.5 in, 1,44 MB (135TPI).
With an LS 120, you can save larger amounts of data on data media than with a
1.44 MB floppy disk drive. The LS 120 has the following properties:
– LS 120 is compatible with the 1.44 MB floppy disk drive – in other words, it
also supports 1.44 MB floppy disks.
– The maximum aggregate is 120 MB with an LS 120 data medium.
– LS 120 is connected via an ATAPI (IDE) interface.
