LCOS Unmanaged Switch ▪ Product Overview19TRANSPORTATION4.2 Overview of product features4.2.1 LCOS Unmanaged Ethernet SwitchesThe 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.4.2.2 Product Features of LCOS Unmanaged Ethernet Switches▪ AC/DC 24V supply voltage ▪ Variable supply voltage supply - Power bus or - 3-pole plug-in terminal Push-In ▪ Can be used as a stand-alone module or in the "Lütze Communication System".▪ Compact design and universal application ▪ QoS - Quality of Services ▪ Extended temperature range▪ CE - Declaration of Conformity▪ UL - Approval ▪ FCC - Approval

LCOS Unmanaged Switch ▪ Commissioning - Hardware41TRANSPORTATION10 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.
LCOS Unmanaged Switch ▪ Commissioning - Hardware42TRANSPORTATION10.2 Safety notes HousingRisk 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.
LCOS Unmanaged Switch ▪ Operation43TRANSPORTATION11 OperationThe 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 functionalities11.2.1 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 ▪ Operation44TRANSPORTATION11.2.3 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 interface11.3.1 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 features11.4.1 Undervoltage cutoff The switch switches off when the voltage falls below a certain level to prevent malfunctions.11.5 Display elementsSee chapter „7.2 LED status displays“ on page 26.
