– Pin configuration
of the RJ45 socket,
RS2-4R:
– 1 line pair: pin 3 and pin 6
– 1 line pair: pin 1 and pin 2
– remaining pins: not used.

100 Mbit/s connection
100 MBit/s F/O ports (DSC sockets) allow
terminal equipment or independent
network segments complying with the
standard IEEE 802.3 100BASE-FX to be
connected.
State on delivery: full duplex.
Note:
Make sure, that you conncet LH ports
only to LH ports, SM ports only to SM ports
and MM ports only to MM ports.
V.24 interface (external management)
A serial interface for local connection of
– an external management station (VT100
terminal or a PC with corresponding ter-
minal emulation) is available via the RJ11
socket (V.24 interface). A link can thus be
established with the User Interface UI.
– an AutoConfiguration Adapter ACA 11 is
available via the RJ11 socket (V.24 interfa-
ce).
VT100 terminal settings:
– Speed:
9,600 Baud
– Data:
8 bit
– Stopbit:
1 bit
– Handshake: off
– Parity:
none
The V.24 interface baud rate can be configu-
red to 9,600 or 19,200 baud. The factory
default is 9,600 baud.
The socket casing is galvanically connected
to the front panel of the device.
Note:
In chapter 6 „Technical data“ you
find the order number for the terminal
access cable which is to be ordered
separately.

1.8 CONTROLS
2-pin DIP switch
Using the 2-pin DIP switch on the RS2-4R
front panel
– on RS2-4R the HIPER-Ring function can be
enabled or disabled with the switch
RING
.
State of delivery: position 0 (Off), i.e. nor-
mal function.
– with the
RM
switch the RM functionality
(Redundancy Manager) can be switched
on or off when HIPER-Ring function is
activated. State of delivery: switch in posi-
tion 0 (Off), i.e. RM function not active.

1.9 INTERFACES
10/100 MBit/s connection
(Twisted Pair)
10/100 Mbit Ports (8-pin R45 sockets) allow
terminal equipment or independent net-
work segments complying with the stan-
dards IEEE 802.3 100BASE-TX / 10BASE-T
to be connected. These ports support auto-
negotiation, autocrossing and the auto-
polarity function.
Factory settings: autonegotiation active (not
valid for HIPER-Ring ports).
The socket casings are electrically connec-
ted to the front panel of the RS2-4R.The pin
configuration complies with MDI-X.

– AutoConfiguration Adapter ACA:
The ACA is a device for saving the confi-
guration data of a MICE, RS2-4R, RS2-
16M, RS2../.. oder MACH 3000 switch. If
one switch should fail, the ACA facilitates
a conceivable simple assumption of the
configuration data by an alternative
switch of the same type.
In case of a reset the switch compares the
contents of the ACA with its own configu-
ration data. If the configuration data do
not correspond, the switch takes over the
configuration data of the ACA.
6pin terminal block
The supply voltage and the indicator
contact are connected via a 6pin terminal
block with screw rast mechanism.

Warning!
The RS2-4R equipments are desi-
gned for operation with a safety
extra-low voltage.Thus, they may
only be connected to the supply vol-
tage connections and to the signal
contact with PELV circuits or
alternatively SELV circuits with the
voltage restrictions in accordance
with IEC/EN 60950.
– Voltage supply
: Redundant voltage sup-
plies are supported. Both inputs are
decoupled. There is no load distribution.
With redundant supply, the power pack
supplies the RS2-4R only with the higher
output voltage. The supply voltage is elec-
trically isolated from the housing.
– Indicator contact:
The indicator contact is used to supervise
the functions of the RS2-4R and thus faci-
litates remote diagnosis.
Contact interrupt indicates the following

contact (relay contact, closed circuit):
