– the failure of at least one of the two
supply voltages.
– a permanent fault in the RS2-4R (inter-
nal voltage supply, supply voltage 1 or 2
< 18 V, ...).
– the faulty link status of at least one port.
The indication of the link state on the
RS2-4R can be masked on a port-by-port
basis using the management software.
State of delivery: there is no link test.
– self test error
The RS2-4R in RM mode can indicate the
following states:
– Ring monitoring is not possible, e. g.
during software initializing.
Note: In the case of the voltage supply
being routed without redundancy, the RS2-
4R indicates the failure of a supply voltage.
You can prevent this message by feeding in
the supply voltage through both inputs.

2. Configuration
2.1 LINE STRUCTURE
The RS2-4R enables backbones in line struc-
tures to be built up. Cascading is effected
using the HIPER-Ring ports (see Fig. 5).
2.2 REDUNDANT RING STRUCTURE
With the RM function (redundancy mana-
ger) of the RS2-4R, RS2-16M, RS2-../..,
MICE, MACH 3000 you can close the two
ends of a line structured backbone to form a
redundant ring.
The RS2-4R is integrated into the ring via
the HIPER-Ring ports (ports 3 and 4). Within
a redundant ring any mixture of RS1, RS2-
4R, RS2-16M, RS2-../.., MICE and MACH
3000 is possible. If one section fails the
recovery time is less than 0.5 seconds for a
ring containing up to 50 switches being cas-
caded and the ring structure is changed
back into a line structure.
Note: The „redundant ring" function requi-
res the following settings for the ports 3
and 4: 100 Mbit/s, full duplex and autonego-
tiation off.
3. Assembly, startup procedure
and dismantling
3.1 UNPACKING, CHECKING
Check whether the package was deliver-
ed complete (see scope of delivery).
Check the individual parts for transport
damage.
Warning!
z
Use only undamaged parts!

3.2 ASSEMBLY
The equipment is delivered in a ready-to-
operate condition. The following procedure
is appropriate for assembly:
Check whether the switch pre-setting
suits your requirements (see chap. 1.7).
Pull the terminal block off the RS2-4R
and wire up the supply voltage and indica-
tor lines.
Fit the RS2-4R on a 35 mm standard bar
to DIN EN 50 022.
Attach the upper snap-on slide bar of
the RS2-4R to the standard bar and press it
down until it locks in position.
Fit the signal lines and if required the
control line.
Always connect the main line and the
redundant line to port 1 (state on delivery)
for the redundant coupling of ring
structures.
