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
LEDs for the Fiber Uplink
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.
