When using USB devices at the USB port of the FRITZ!Box,
please keep in mind the following;
If more than one USB device without its own power
supply is connected to the FRITZ!Box, note that, in ac-
cordance with the USB specification, the total current
consumption may not exceed a value of 500 mA. Oth-
erwise unspecified malfunctions with the USB devices
or even damage to the FRITZ!Box may occur.
AVM expressly advises against installing firmware up-
dates for USB devices connected to the computer via
the USB remote connection on the FRITZ!Box.
When using a USB storage device at the USB port of the
FRITZ!Box, please keep in mind the following:
Before removing the USB storage device, select the
"Remove Safely" button in the FRITZ!Box user inter-
face to prevent losses of data.
To avoid damage to the FRITZ!Box or the USB storage
device, operate USB storage devices that require more
than one USB port for operation (for instance hard
drives with a Y cable) only if they have their own power
supply or a USB hub with its own power supply.
AVM has no influence over external interference to the
USB storage devices on the FRITZ!Box. Thus such phe-
nomena as voltage spikes during storms may occur,
and writing to older USB memory devices may corrupt
the data structure due to a high number of defective
structures. In such cases a complete loss of data may
occur.
Therefore AVM recommends always making a security
copy of the USB memory content so that your data are
not irretrievably lost.
