6.1 Retrofitting instructions
An Slimline DVD RW drive can be installed optionally. This may only be operated under
consideration of the following instructions.
Danger of data errors when burning data carriers (DVD RW)
Burning is permissible only in an undisturbed environment, i.e. shock and vibration stress
must be avoided.
Because of heavy fluctuation in the quality of CD-Rs, data may be corrupted in a burning
session, even if no error message is initially displayed.
The written data can only be verified by comparing these with the source. To be on the safe
side, data should be verified after every burning session.
Note
During operation, the HDDs installed in the removable drive bay must not be exposed to
vibratory loads and may only be exposed to limited shock loads (see Technical
specifications).
Temperature range 5 °C to 45 °C
The maximum permissible power loss of the expansion cards amounts to 55 W. An ODD

Distribution to the slots without exceeding the total power:
● 25 W for Slot 1 maximum
● 25 W each for Slot 2, 3 maximum
● 15 W for Slot 4 maximum
