General
The DIN-rail mounting switch-con-
struction kit has been developed
to fulfill the high data rate require-
ments of network engineering and
to allow for an expansion of the
network.
Consisting of master- and slave-
device – from now on known as
switching system – theese active
network components are plugga-
ble together and provided for a
networking of up to 10 terminal
devices (8 devices with 10/
100 Mbit/s and 2 devices with
10/100/1000 Mbit/s). For this
connection no front ports are
used.
They are designed as DIN-rail
components for the moun-
ting in an electrical distribution
respectively on the DIN-rail of a
distribution box and is excellently
suited for the assembly of smaller
or middle network installations
12
in private home and small-scale
(SOHO, s. figure 5).
The switch system does not
require any operating elements for
the user or installer.
The switching system provides
the following features:
·
arbitrarily cascadable by
using front ports
·
4096 MAC-adresses sto-
rable
·
autosensing
·
autonegotiation
·
autopartitioning
·
store-and-forward-princi-
ple
·
MDI/MDIx
Function
Data are transmitted to the port
of the switching system on which
the PC with the corresponding
destination address is connected.
This unloads the network and
makes it faster. If the destination
address is unknown, the data will
be transmitted to all ports just like
a hub would do.
Eight of the ten ports work
independently at a rate of 10/
100 Mbit/s and 2 ports at 10/
100/1000 Mbit/s in half- or full
duplex operation (automatic shif-
ting depending on the connected
devices). One port of each com-
ponent is suitable for Gigabit-
Ethernet and usable as an uplink
port for the cascading of further
switches or to realize a faster
data application.
The data rate depends on the
connected terminal device and is
automatically recognized (auto-
sensing) and switched over by
