Hirschmann RS2-5TX/FX, RS2-5TX Description And Operating Instructions

Description and operating instructions
Industrial ETHERNET Rail Switch

The Rail Switches RS2-5TX and RS2-5TX/FX

have been especially designed for use in

industrial environments.

They support

ETHERNET 10 MBit/s and Fast ETHERNET
100 MBit/s.

The Rail Switch modules support switched
ETHERNET networks in accordance with
IEEE standard 802.3 using copper and fiber
optic technology. The switch modules are
plugged onto the standard

DIN rail. Because
of their compact design the modules can be
mounted in a terminal box.

The RS2-5TX modules have five
10/100 MBit/s twisted pair ports
(

10/100BASE-TX, RJ45 connectors).

It is possible to connect up to five DTEs

(data terminal equipment)

or other TP/TX
network segments to these ports using
twisted pair cabling.

The RS2-5TX/FX modules have four
10/100 MBit/s twisted pair ports
(10/100BASE-TX, RJ45 connectors) and one
100 MBit/s fiber optic port (100BASE-FX,
MTRJ connector).
It is possible to connect up to four DTEs or
other TP/TX network segments to the TP/TX
ports using twisted pair cabling. One further
DTE or an optical network component can
be connected to the fiber port.

The TP ports support auto negotiation and
autopolarity.
The operating mode of the FX port is full
duplex.

Note

We would point out that the content of
these operating instructions is not part of,
nor is it intended to amend an earlier or exi­sting agreement, permit or legal relation­ship. All obligations on Hirschmann arise
from the respective purchasing agreement
which also contains the full warranty condi­tions which have sole applicability. These
contractual warranty conditions are neither
extended nor restricted by comments in
these operating instructions.

We would furthermore point out that for
reasons of simplicity, these operating
instructions cannot describe every
conceivable problem associated with the
use of this equipment. Should you require
further information or should particular
problems occur which are not treated in
sufficient detail in the operating instruc­tions, you can request the necessary infor­mation from your local Hirschmann sales
partner or directly from the Hirschmann
office (address: refer to chapter entitled
„Notes on CE identification“).

Safety Instructions

This manual contains instructions which
must be observed to ensure your own per­sonal safety and to avoid
damage to devices and machinery. The
instructions are highlighted with a warning
triangle and are shown as
follows according to the degree of endan­germent:

z

Danger!

means that death, serious injury or
considerable damage to property
will result if the appropriate safety
measures are not taken.

z

Warning!

means that death, serious injury or
considerable damage to property
can result if the appropriate safety
measures are not taken.

z

Caution!

means that light injury or damage to
property can result if the appropria­te safety measures are not taken.

Note: is an important piece of information
about the product, how to use the product,
or the relevant section of the documentati­on to which particular attention is to be
drawn.

Certified usage

Please observe the following:

z

Warning

The device may only be employed
for the purposes described in the
catalog and technical description,
and only in conjunction with external
devices and components recommen­ded or approved by Hirschmann.
The product can only be operated
correctly and safely if it is transpor­ted, stored, installed and assembled
properly and correctly. Furthermore,
it must be operated and serviced
carefully.

Safety Guidelines
Power Supply

䡺 Switch the basic devices on only when
the case is closed.

z

Warning!

The devices may only be connected
to the supply voltage shown on the
type plate.

The devices are designed for opera­tion with a safety extra-low volta­ge.Thus, they may only be connec­ted to the supply voltage connec­tions and to the signal contact with
SELV circuits with the voltage
restrictions in accordance with
IEC/EN 60950-1.

䡺 For the case where the module is opera­ted with external power supply: Use only a
safety extra-low voltage in accordance with
IEC/EN 60950-1 to power the system.

䡺 First of all you connect the protecting
line, before you establish the further
connections. When you remove connec­tions, you disconnect the protecting line
last.

䡺 Relevant for North America:
The subject unit is to be suppplied by a
Class 2 power source complying with the
requirements of the National Electrical
Code, table 11(b). If power is redundant
supplied (two individual power sources) the
power sources together should comply with
the requirements of the National Electrical
Code, table 11 (b).

䡺 Relevant for North America:
Power, input and output (I/O) wiring must
be in accordance with Class I, Division 2
wiring methods [Article 501-4(b) of the
National Electrical Code, NFPA 70] and in
accordance with the authority having juris­diction.

Peripheral equipment must be suitable for
the location it is used in.

Use 60/75°C or 75°C copper(CU)wire only.

Safety Guidelines
Shielding Ground

Note: The shielding ground of the connec-

table twisted pairs lines is connected to the
front panel as a conductor.

䡺 Beware of possible short circuits when
connecting a cable section with conductive
shielding braiding.

Safety Guidelines Housing

z

Warning!

Only technicians authorized by Hir­schmann are permitted to open the
housing.

Note: The device is grounded via the sepa­rated ground screw. It is located on the left
under the front panel.

䡺 Make sure that the electrical installation
meets local or nationally applicable safety
regulations.

z

Warning!

The ventilation slits must not be
covered so as to ensure free air cir­culation.

The distance to the ventilation slots
of the housing has to be a minimum
of 10 cm.

Never insert pointed objects (thin
screwdrivers, wires, etc.) into the
inside of the subrack! This especial­ly applies to the area behind the
socket connectors. Failure to obser­ve this point may result in injuries
caused by electric shocks.

Note: If installed the device must be opera­ted exclusively in switch cabinets with fire
protection characteristics according to
IEC/EN 60950-1.

Note: The housing has to be mounted in
upright position.

Safety Guidelines Environment

z

Warning!

The device may only be operated in
the listed ambient temperature
range at the listed relative air humi­dity (non-condensing).

䡺 The installation location is to be selec­ted so as to ensure compliance with the cli­matic limits listed in the Technical Data.

䡺 To be used in an up to Pollution Degree
2 environment only (IEC 60664-1).
