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, unplug the wall plug trans-
former from the mains socket (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, 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 connection
and wiring. Do NOT connect the gigabit switch yourself!
• The twisted-pair cable (also called a patch cable) between the gigabit switch and the device
to be connected should have a max. length of 100m. Use only so-called CAT5e cables that
are fully wired (all 8 contacts of the RJ45 connector are connected 1:1).
• With the connection of several network switches you can use conventional 1:1 connected
network cables as the gigabit switch provided has an auto uplink function. Thus, the expen-
sive crosslink cables are not necessary.
• The maximum theoretical data transfer rate of 10, 100 or 1000MBit/s is usually not achieved
in practice (e.g. 1000MBit = approx. 125MByte/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 gigabit switch is not supplied with power, all the connections will be out of operation. A
network connection is not possible.
• You can control the network connection by means of the LED of each network port of the
gigabit switch.
The respective LED lights up in the Steady mode when there is a smooth network connection
or it fl ashes during data transmission.
If the LED goes off, please check the following:
- Is the power-LED on the gigabit switched on? If no, check the power supply of the gigabit
switch.
- Is the connected network device (e.g. computer) switched on?
- Is the network cabling faultless? For test purposes, use another network cable or check
whether the RJ45 connect pins are inserted properly in the corresponding socket. If net-
work sockets are used, check their cabling.
Is there a loop connection? A loop connection is created accidentally e.g. connecting two
network ports of the gigabit switch to one another via cable or another network switch.
Disconnect this loop connection by removing one of the two network cables from the gigabit
switch.
• In comparison to other network switches, the gigabit switch saves energy because it auto-
matically switches off unused ports or changes their mode to stand-by mode.
Furthermore, depending on the cable length and the design of the network cable connected,
the gigabit switch is able to reduce the energy required for the data transfers, which thus
helps to save more energy.
Disposal
Electrical and electronic products do not belong in the household waste!
Please dispose of the product, when it is no longer of use, according to the current
statutory requirements.
