1 - Floppy disk indicator
The indicator lights up when the floppy disk drive of the system unit is accessed. You may only
remove the floppy disk when the indicator is unlit.

The indicator lights up when the CD-ROM drive of the system unit is accessed. You may only
remove the CD when the indicator is dark.
3 - Hard disk indicator
The indicator lights up when the hard disk drive of the system unit is accessed.
4 - Power-on indicator
−
green:
The system unit is on.
−
orange:
The system unit is ready-to-operate.
In this mode the PC consumes very little power and can be switched on at the ON/OFF
switch.
−
flashing green/orange:
The indicator only flashes on systems which support the ACPI function (Advanced
Configuration and Power Management Interface).
The system unit is in the energy-saving mode (standby). After being switched on with the
ON/OFF switch, the PC returns to the state it was in before the energy-saving mode. In
the energy-saving mode the system unit may not be disconnected from the power supply,
as this may otherwise result in data loss.
