Use either the MiniUSB or the MicroUSB port. Never use both ports at the same
time.
• The network switch‘s RJ45 connections must be connected to the appropriate RJ45 ports
on the network cards (or another network switch) using suitable network cables (we recom-
mend cables that meet the standard CAT5e).
The network switch supplied has automatic uplink recognition for each port, which
allows for particularly simple wiring to other switches. A cross-link cable is no longer
required; you can use a conventional 1:1 connected network cable.
Maintenance and cleaning
• The product does not require any maintenance and should never be disassembled for any
reason.
• Disconnect the product from the power supply before cleaning (all network connections will
cease to function).
• Dust can easily be removed using a clean, soft brush and a vacuum cleaner.
• Do not use aggressive cleaning agents as these can cause discolouration.
• Do not press too strongly on the surface when cleaning, to prevent scratch marks.
Tips & notes
• If you have your own network or system administrator for your network (as will probably be
the case in a larger company), please let this person assume the responsibility for connec-
tion and wiring. Do not connect the network switch yourself!
• The twisted-pair cable (also called a patch cable) between the network switch and the
device to be connected should have a max. length of 100 m. Use as a minimum so-called
CAT5e cables, which are fully wired (all 8 contacts of the RJ45 connector are connected
1:1).
• The maximum theoretical data transfer rate of 10 or 100 MBit/s is usually not achieved in
practice (e.g. 100MBit = approx. 12.5MByte/s). During data transmission, not only data, but
also protocol information etc is transmitted, data packages must be repeated or different
computers may want to transmit data at the same time. Furthermore, the data for example
may need to be read off the hard disk of one computer and written onto the hard disk of
another computer.
• If the network switch is not supplied with power, all the connections will be out of operation.
A network connection is not possible.
• The Link/Act LED belonging to each RJ45 port is lit during an active network connection
and ashes during data transfer. The power LED is lit when the network switch is supplied
with power.

Safety Instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information on
proper handling in this manual, we assume no liability for any resulting per-
sonal injury or damage to property. Such cases will invalidate the warranty/
guarantee.
• The product is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This may become dan-
gerous playing material for children.
• Protect the product from extreme temperatures, direct sunlight, strong jolts, high
humidity, moisture, ammable gases, steam and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed
if the product:
• is visibly damaged,
• is no longer working properly,
• has been stored for extended periods in poor ambient conditions or
• has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
• Consult an expert when in doubt about the operation, safety or connection of the
product.
• Maintenance, modications and repairs must only be completed by a technician
or an authorised repair centre.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
Getting started, connection
• Connect the switch to a USB port on your computer or to a USB hub using the USB power
cable enclosed.
The USB port must be able of supplying a current of 500 mA. Therefore, you will
need, for example, a USB port on a computer or a USB hub with a separate power
supply.
The USB port on a keyboard, or a USB hub without a power adapter, does not sup-
ply sufcient current; the switch cannot be used in these cases!
• As an alternative to the enclosed USB power cable, an external wall plug transformer may
also be used (not included, can be ordered separately). This must supply an output voltage of
5 V/DC and a current of at least 500 mA.
• The switch has a MiniUSB and a MicroUSB port. Therefore, you can use a wall plug trans-
former with one of the two suitable connectors.
