not possible to rule out deviations comple-
tely, so we are unable to guarantee comple-
te agreement. However, the details in the
technical publication are checked regularly.
Any corrections which prove necessary are
contained in subsequent editions. We are

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 exi-
sting agreement, permit or legal relation-
ship. All obligations on Siemens arise from
the respective purchasing agreement which
also contains the full warranty conditions
which have sole applicability. These con-
tractual 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 instruc-
tions, you can request the necessary infor-
mation from your local Siemens office.
General
Electricity is used to operate this equip-
ment. Comply in every detail with the safety
requirements specified in the operating
instructions regarding the voltages to
apply!
Warning!
v
If warning notes are ignored, it is
therefore possible for severe injuries
and/or material damage to occur.
Only appropriately qualified staff
should work on or near this equip-
ment. Such staff must be thoroughly
acquainted with all the warnings
and maintenance measures contai-
ned in these operating instructions.
The proper and safe operation of
this equipment assumes proper
transport, appropriate storage and
assembly and careful operation and
maintenance.

Staff qualification
requirements
Qualified staff within the meaning of these
operating instructions or the warning notes
are persons familiar with setting up, assem-
bling, starting up and operating this product
and who have appropriate qualifications to
cover their activities, such as:
– training or instruction/entitlement to
switch circuits and equipment/systems on
and off, earth them and identify them in
accordance with current safety standards;
– training or instruction in accordance with
current safety standards in looking after
and using appropriate safety equipment;
– first aid training.
Safety guidelines
Warning!
v
The ORM units are designed for
operation with safety extra-low vol-
tage. Accordingly, only safety extra-
low voltages (SELV) to
IEC950/EN60950/VDE0805 may be
connected to the supply voltage
connections.
1. Functional description
The Industrial Ethernet™ ORM has 2 F/O
ports (100 Mbit/s). A free end of an OSM
line is connected to each port.
1.1 INTERFACES
F/O ports
Two optical ports to 100BASE-FX (BFOC/2,5
(ST) sockets) enable to configure a redun-
dant 100 Mbit/s backbone.
According to IEEE 802.3 standard 100BASE-
FX an ORM monitors the attached F/O lines
for open circuit conditions.
5-pin terminal block
The supply voltage and the indicator
contact are connected via a 5-pin terminal
block with screw locking mechanism.
Warning!
v
Industrial Ethernet™ ORMs are desi-
gned for operation with SELV. Only
safety extra-low voltages to
IEC950/EN60950/VDE0805 may
therefore be connected to the
supply voltage connections and to
the indicator contact.
– Voltage supply: The voltage supply can
be connected to be redundant. Both
inputs are decoupled. There is no load
distribution. With redundant supply, the
power pack supplies the ORM alone with
the higher output voltage. The supply vol-
tage is electrically isolated from the
housing.
– indicator contact: Contact interrupt
indicates the following by means of a
potential-free indicator contact (relay
contact, closed circuit):
– the failure of at least one of the two
supply voltages.
– a permanent fault in the ORM (internal
5 V DC voltage, supply voltage 1 or 2 not
in the permissible range).
– the faulty link status of at least one F/O
port.
– at least one port has auto partitioned.
– selft test error
Note: In case of the voltage supply being
routed without redundancy, the ORM indi-
cates the failure of a supply voltage. You
can prevent this message by feeding in the
supply voltage through both inputs.

1.2 DISPLAY ELEMENTS
Equipment status
These LEDs provide information about sta-
tuses which affect the function of the entire
ORMs.
L1 – Line 1 (green LED)
– lit: – supply voltage 1 present
– lit not: – supply voltage 1 is less than 18 V,
– hardware fault in ORM
L2 – Line 2 (green LED)
– lit: – supply voltage 2 present
– lit not: – supply voltage 2 is less than 18 V,
– hardware fault in ORM
CPU – System (Green/red LED)
– lit not: – Initializing, hardware self
test
– lit red: – Self test error
– flashes red (1 Hz):
– Loading software
– lit red with interruption:
– Writing to Flash EPROM
– lit yellow: – The User Interface (V.24)
is occupied
– flashes yellow (0,5 Hz):
– The system is initialized
and runs fault-free.
