XSNet 1600 MC
10/100Base to 100Base-FX media converter
USER MANUAL
1. General description
The XSNet 1600 Series 10/100 to 100Base-FX
Media Converters allow incorporation of a copper-
based Ethernet 10/100Base-TX into a fibre-optic
100Base-FX Fast. They use store-and-forward at
full wire speed, and are compatible with other
10Base-T & 100Base-TX/FX devices. The 1600
MC connects to two multimode fibres, the 1640
MC uses two single-mode fibres and the 1650 MC
needs only one single-mode fibre.
In full-duplex mode, this converter can span
distances of up to 2 kilometres for multimode fibre
and up to 100 kilometres for long-haul single-mode
fibre between networking devices.
Auto-negotiation (N-Way support), manual half- or
full-duplex mode on the fibre port, manual half/full-
duplex mode and speed selection on the copper
port, Link Fault Signalling (LFS) and both Remote
and local loopback Test can be selected via DIP
switches. The automatic MDI detection setting
feature allows for automatic cable type
configuration when establishing a connection
between RJ45 ports.
Front panel LEDs provide instant information about
the device's network and connectivity status.
An XSNet 1600 MC series converter, housed in a
compact stand-alone box which can also be
mounted on a vertical surface, is powered with an
230 VAC/12 VDC adapter, which is included in the
package, together with rubber feet and mounting
screws.

3. Configuration
Data cable wiring: the auto-MDI function will
automatically take care of cable type configuration
when connecting the converter to a 10/100Base-TX
device.
In order to configure duplex modes and speed (with
dip switches 2, 3 and 4, see table 2 and figure 2),
dip switch 1 (auto-negotiation) must be set to OFF;
if not, the media converter will try to adapt
automatically.
Note: Setting the duplex mode is feasible while the
media converter is in operation.
Dip switch Function

4. Installation and testing
4.1. Installation
The converter can be used as a stand-alone box,
using the 4 rubber feet included in the package.
Alternatively, the two screws included may be used
to affix the unit to a vertical, flat surface, fitting the
screws’ heads in the two keyholes in the converters
bottom side.
Please observe the following precautions:
- do not expose the unit to heat, moisture or dust or
similar detrimental influences
- keep some free space around the unit for air
circulation (there are vents in the sides of the unit).
Connect suitable optical and data cabling: CAT3
for 10Base-T and CAT5 for 100BaseTX.
4.2. Loopback tests
A local loopback test can be performed to check
whether the copper side is working and connected
correctly; please use dip switch 6.
The remote loopback test serves a similar purpose
for the fibre segment, using dip switch 7.
For a local test, you will need just one workstation
or similar device to set up a copper link to one
converter; to perform the remote loopback test, you
will need the previous setup together with a second
converter having a fibre connection to the first one;
see figure 3.
Remote and local testing should not be done
simultaneously. For normal converter operation,
disable both local and remote loopback testing.
5. Operation
5.1. Normal operation
Normal operation will be apparent from the LED
patterns described in table 1, with loopback off. If
auto-negotiation is not active, please make certain
that the duplex mode and speed settings match
those of non-adapting devices connected.
5.2. Link fault signalling
The LFS LED will immediately light to indicate
when a cable has been severed or when some other
service disruption has occurred.

Four converters can be used to build a primary and
a secondary link, connected to a switch that
supports Spanning Tree or Fast Spanning Tree
protocols. By default, data will travel via the
primary link. Once a fault has been detected by the
converter, transmission will automatically switch to
the secondary link, yielding non-stop network
connectivity.
Note: The LFS feature works for both the fibre and
copper segments. Therefore, in case of disruption in
either segment, the LFS LED will indicate that the
entire connection is down.

7. Safety, EMC, ESD
General
The safety information contained in this section, and on
other pages of this manual, must be observed whenever this
unit is operated, serviced, or repaired. Failure to comply with
any precaution, warning, or instruction noted in the manual
is in violation of the standards of design, manufacture, and
intended use of the unit.
Installation, adjustment, maintenance and repair of this
equipment are to be performed by trained personnel aware of
the hazards involved. For correct and safe use of the
equipment and in order to keep the equipment in a safe
condition, it is essential that both operating and servicing
personnel follow standard safety procedures in addition to the
safety precautions and warnings specified in this manual, and
that this unit be installed in locations accessible to trained
service personnel only.
Optelecom-NKF assumes no liability for the customer’s
failure to comply with any of these safety requirements.
UL/IEC/EN 60950-1: General safety requirements
The equipment described in this manual has been
designed and tested according to the UL/IEC/EN 60950-1
safety requirements.
If there is any doubt regarding the safety of the equipment, do
not put it into operation. This might be the case when the
equipment shows physical damage or is stressed beyond
tolerable limits (e.g. during storage and transportation).
Before opening the equipment, disconnect it from all power
sources. The equipment must be powered by a SELV*) power
supply.
When this unit is operated in extremely elevated temperature
conditions, it is possible for internal and external metal
surfaces to become extremely hot.
Optical safety
This optical equipment contains Class 1M lasers or LEDs
and has been designed and tested to meet IEC 60825-
1:1993+A1+A2 and IEC 60825-2:2004 safety class 1M
requirements.
Optical equipment presents potential hazards to testing and
servicing personnel owing to high levels of optical radiation.
When using magnifying optical instruments, avoid looking
directly into the output of an operating transmitter or into the
end of a fibre connected to an operating transmitter, or there
will be a risk of permanent eye damage.Precautions should
be taken to prevent exposure to optical radiation when the
unit is removed from its enclosure or when the fiber is
disconnected from the unit. The optical radiation is invisible
to the eye.
Use of controls or adjustments or procedures other than
those specified herein may result in hazardous radiation
exposure.
The installer is responsible for ensuring that the label
depicted below (background: yellow; border and text: black)
is present in the restricted locations where this equipment is
installed.
The locations of all optical connections are listed in the
Indications and Connectors section of this manual.
Optical outputs and wavelengths are listed in the Technical
Specifications section of this manual.
Hazard Level 1M

4
EMC
The equipment has been tested and found to meet the CE-
regulations relating to EMC, and complies with the limits
for a Class B device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection
against interference to radio communications in any
installation. The equipment generates, uses and can radiate
radio frequency energy; improper use or special
circumstances may cause interference to other equipment or a
performance decrease due to interference radiated by other
equipment. In such cases, the user will have to take
appropriate measures to reduce such interactions between this
and other equipment.
Any interruption of the shielding inside or outside the
equipment could cause the equipment to be more prone to fail
EMC requirements.
Non-video signal lines must use appropriate shielded CAT5
cabling (S-FTP), or at least an equivalent.
If system components, such as cabling (e.g. coaxial cable,
data/audio/cc wiring) and/or the units, are used outdoors,
ensure that all electrically connected components are
carefully earthed and protected against surges (high voltage
transients caused by switching or lightning).
ESD
Electrostatic discharge (ESD) can damage or destroy
electronic components. Proper precautions should be
taken against ESD when opening the equipment.
*) SELV: conforming to IEC 60950-1, <60VDC output, output
voltage galvanically isolated from mains. All power supplies or
power supply cabinets available from Optelecom-NKF comply
with these SELV requirements.
