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 (PB) 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.
