Resetting to Factory Settings
On the front on the left, next to the LEDs, a countersunk reset button can be found, using this
the switch can be reset to the factory settings.
Connect the switch to the mains voltage, if it has not already been done. Press and hold the
„Reset" key for 5 seconds and release it afterwards.
The switch restarts, this takes about 20 seconds. Afterwards the switch is reset to the factory set-
tings (IP address 192.168.2.1; user name and password „admin" respectively).
Handling
• Only use in dry indoor locations. The product must not get damp or wet! There is
risk of an electric shock!
• Never use the product immediately after it has been taken from a cold room to a
warm one. The condensation that forms might destroy your unit. There is risk of an
electric shock!
Allow the product to reach room temperature, before connecting it to the power
supply and putting it in to use. This may take several hours.
• Any maintenance or repair work may only be carried out by authorised personnel.
• Check the product for damage before each use!
If you detect any damage, DO NOT connect the product to the mains supply! This
presents a danger to life!
• A safe operation can no longer be assumed, if:
- the product shows visible signs of damage,
- the product does not function or does not function properly (e.g. a burning smell)
- the product was stored under unfavourable conditions
• When setting up the product, make sure that the cables are neither kinked nor
pinched.
• If you do not use the product for a longer period of time (e.g. during storage),
disconnect the power plug from the mains socket (all the network connections
cease to function!).
• Avoid the following unfavourable environmental conditions at the installation
location and during transportation:
- Excessive humidity or damp
- Extreme cold or heat, direct sunlight
- Dust or flammable gases, fumes or solvents
- Strong vibrations, impacts or blows
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 mains plug 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 network switch yourself!
• The twisted-pair cable (also called a patch cable) between the 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).
• 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 via the network, 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.
• If the switch is not supplied with power, all the connections will be out of operation. A network
connection is not possible.
