Tips for Using USB Devices
When using USB devices at the USB ports 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, please note
that, in accordance with the USB specification, the
total current consumption may not exceed a value of
500 mA. Otherwise unspecified malfunctions with
the USB devices or even damage to the FRITZ!Box
may occur.
•
AVM expressly advises against performing firmware
updates for USB devices connected to the computer
via the USB remote connection on the FRITZ!Box.
•
Before removing a USB storage device, select the
“Remove safely” option in the FRITZ!Box user inter-
face to prevent losses of data.
•
To avoid damage to the FRITZ!Box, only operate USB
storage devices that require more than one USB port
for operation (for instance hard drives with a Y cable)
if they have their own power supply or a USB hub
with its own power supply.
•
The FRITZ!Box can not defend the USB memory from
external influences. Thus such phenomena as volt-
age spikes during storms may occur, and writing to
older USB memory devices may corrupt the data
structure due to a high number of defective struc-
tures. In such cases a complete loss of data may oc-
cur.
Therefore we recommend always backing up the USB
memory content just in case data are lost on the USB
storage device.
