4.2 Overview of product features
4.2.1 LCOS Unmanaged Ethernet Switches
The LCOS-SW-4P or LCOS-SW-8P Unmanaged Ethernet Switch is a switch for
use in industrial environments. It supports ETHERNET 10 MBit/s and Fast
ETHERNET 100 MBit/s.
The switch modules enable the construction of switched Ethernet networks
according to the IEEE 802.3 or 802.3u standard with twisted-pair cables.
The switch modules can be mounted directly on the top-hat rail via a function
carrier and are powered either via the LCOS power bus or the 3-pole connection
terminal. With their compact design, the modules can be mounted in a terminal
box.
The LCOS-SW-4P devices have four 10/100 Mbps twisted pair ports (10/
100BASE-TX, RJ45 connectors) and the LCOS-SW-8P devices have eight 10/
100 Mbps twisted pair ports (10/100BASE-TX, RJ45 connectors).
Twisted pair devices or other TP/TX segments can be connected to the ports. The
TP ports support auto negotiation, auto polarity and auto MDI/MDI-X. In addition,
the devices evaluate the Ethernet frame-based priority data (Qos) in order to
forward time-critical signals more quickly.
The power consumption is significantly reduced by an automatic switch-off of the
unused ports, but even at full load the power consumption of the 8 port version
remains below 2W. The extended operating temperature range allows operation
from - 25 °C to + 70°C ambient temperature.

41
TRANSPORTATION
10 Commissioning - Hardware
10.1 Safety notes Power supply
The supply voltage is galvanically isolated from the housing. The devices can be
supplied either via the energy bus X10 or the connection terminal X9. The power
bus and the connection terminal are internally connected. Polarity is irrelevant.
Commissioning of the hardware may only be carried out by qualified per-
sonnel in compliance with the safety regulations.
Only switch on a device when the housing is closed.
Electric shocks and short-circuits due to incorrect voltage application.
Before commissioning, disconnect the entire system from the power supply and
check the connections after applying power.
The devices may only be connected to the supply voltage printed on the
identification plate.
The devices are designed for operation with safety extra-low voltage.
Accordingly, only SELV/PELV voltage circuits may be connected to the
supply voltage connections.
The earth connection of the device serves exclusively as functional earth
(FE) according to EN 61131-2.
Make sure that peripherals are suitable for the application environment.
The connecting cables must be designed for the ambient temperature.
If the switches are supplied with AC, surge voltages of up to 2000 V can
be expected between the active conductors and earth.
However, since the isolation voltage between functional earth (FE) and active
conductors is only 1000 V, external overvoltage protection is required between
the functional earth and at least one active conductor.
This overvoltage protection must limit the voltage to 1000 V.
Varistors of type 7N431K can be used for this purpose, for example.

10.2 Safety notes Housing
Risk of electric shock!
The housing may only be opened by technicians authorised by Lütze.
The upper and lower ventilation slots must not be covered so that the air
can circulate freely.
The distance to the ventilation slots of the housing must be
at least 30 mm.
Never insert pointed objects (narrow screwdrivers, wires or similar) into
the inside of the product! There is a risk of electric shock.
The housing must be installed in a vertical position.

TRANSPORTATION
11 Operation
The device is delivered ready for operation.
11.1 Functional description
The ports of the LCOS Switch represent a terminal device connection for the
connected LAN segment. You can connect individual devices or entire network
segments.
11.2 Frame-Switching functionalities
11.2.1 Store and Forward
All data received by a switch is stored and checked for validity. Invalid and faulty
data packets are discarded. Valid data packets are forwarded. Data packets with
a length of up to 1552 bytes are supported. The packet buffer size is 448k bits.
11.2.2 Multi-address capability
A switch learns all source addresses per port. Only packages with
▪ unknown addresses
▪ these addresses or
▪ a multi-/broadcast address
in the destination address field are sent to this port.
Up to 1000 addresses can be stored simultaneously. This is necessary if more
than one terminal is connected to one or more ports. This allows several
independent subnets to be connected to one switch.
Operation must be carried out by at least trained personnel.
Do not touch the housing during operation or shortly after switching off.
Hot surfaces can cause injuries.
Proper and safe operation of the product requires careful operation and
maintenance.
With the connection of the supply voltage you put the switch into
operation.
LCOS Unmanaged Switch ▪ Operation
44
TRANSPORTATION
11.2.3 Tagging (IEEE 802.1Q)
For the VLAN and prioritisation functions, the IEEE 802.1 Q standard provides
that the VLAN tag is integrated into a MAC data frame. The VLAN tag consists of
4 bytes (2 bytes Tag Protocol Identifier TPID, 2 bytes Tag Control Information
TCI). It is inserted between the source address field and the type field. Data
packets with VLAN tag are transmitted unchanged by the switch.
11.3 Specific functions of the Ethernet interface
11.3.1 Polarity reversal (Auto-Polarity)
If the pair of receiving lines is incorrectly connected (RD+ and RD- reversed), the
polarity is automatically reversed.
11.3.2 Auto MDI-MDIX
The switch detects the transmit and receive line pair. The switch automatically
switches the port output and port input to the corresponding line pairs. Therefore,
it does not matter whether you use a cross-over or uncrossed cable to connect a
device.
11.4 Other functions and features
11.4.1 Undervoltage cutoff
The switch switches off when the voltage falls below a certain level to prevent
malfunctions.

Four (LCOS-SW-4P) or eight (LCOS-SW-8P) ports allow the connection of end
devices or independent network segments according to the IEEE 802.3
100BASE-TX / 10BASE-T standards.
Pin assignment of the RJ45 socket: See chapter „9.4 Pin assignment“ on
page 37.
The unit is to be connected only to internal Ethernet networks without
exiting a facility and being subjected to TNVs.
To avoid electric shock, this device may only be connected to Ethernet
networks within a building that are not connected to TNV circuits. Do not use a
telephone line voltage (TNV)! (This note is particularly relevant for North
America and Canada.)
The input/output connections comply with the Safety Extra Low Voltage (SELV)
guidelines for extra-low voltage devices. With TNV circuits, higher voltages
must be expected, e.g. due to lightning strikes. Therefore, they must not be
connected to SELV circuits.
