MICROSENS
5 Port Mini Switch
General
The MICROSENS mini switch offers the connection of four end devices via twisted pair
cable. An additional fiber uplink port (100Base-FX) is for the connection to the central
distribution.
The mini switch has a very compact design. Especially in the end device area the use of
this mini switch is very cost effective, this makes him very useful for small workgroups.
The RJ-45 ports are selecting the speed of the connected device (10/100
autonegotiation) automatically. Due to its auto crossing function the switch recognizes
the pin out of the TX port, which allows to use always standard patch cables.
The fiber optic uplink port for the connection to the central distribution is working
with 100 Mbps and can be used in half or full duplex mode, depending on the
requirements. Using single mode fiber it is possible to cover distances up to 100 km.
This desktop version can be mounted onto walls with the optional available wall mount
bracket. Further models are designed for the installation into cable trunks and sub
floor systems.

Features
The switch has a non blocking architecture and is working with the store and forward
procedure. For data storage the switch has an integrated memory of 1 Mbit.
The MAC address handling is done by the integrated address management. The switch
can store up to 1024 MAC addresses. A Mac address is stored after receiving a valid
data packet. Five to ten minutes after receiving the last packet the related address is
deleted (aging).
Connections
Due to the integrated auto crossing feature a separation of 1:1 and crossed patch
cables is no longer necessary. The switch detects the pin out automatically and
configures itself according. The offers to connect end devices and to cascade switches
with the same patch cable.
Transmission Speed
The twisted pair ports are configuring them selves to the maximum possible speed. The
LEDs are showing the selected speed.

LEDs for the Twisted Pair Ports
If the Act/Speed LEDs are lightning green, a Fast Ethernet (100 Mbps) connection is
established. For an Ethernet (10 Mbps) connection theses LEDs are yellow. The fiber
uplink is a pure 100Base-FX port. The link detection is indicated by a green LED.
The transmission in full duplex mode is indicated by the related LED. If the connection
is established in half duplex mode the related LED is flashing. The transmission mode of
the fiber uplink port is configured with the DIP switches. It has to be considered that
distances over 412 m can be reached only in full duplex mode. To activate the full
duplex mode the DIP switch must be in the top position.

Power Supply
The power supply is done by an external power supply. This power supply is included at
delivery. Because of warranty reasons only the MICROSENS power supplies have to be
used. Attention, in order to avoid damages the voltage shown on the switch and the
power supply must be the same!

Mounting
The MICROSENS mini switch is designed as a desktop unit. With the delivered wall
mounting bracket it is very easy to mount this desktop switch onto the wall.
For a better visibility the LED’s are showing to the top. The cable connections are
showing to the bottom side to ensure a kink free connection.
With the optional available DIN rail holder it is possible to mount the switch on 35 mm
hat rails.
Safety Notes
DANGER! Optical components can emit invisible laser radiation.
ATTENTION: Infrared light as it is used for data transmission on optical fibres is not
visible to the human eye, but nevertheless may cause severe damage.
In order to prevent any eye damage:
Never look into the output of optical fibres or components - risk of severe eye
damage!
Apply protective caps to all unused optical ports.
Do not start system operation prior to completing all wiring.
Active laser components employed in this system comply with laser safety class 1.
