The example of a coupling between two ring networks using two SCALANCE X101-1 media
converters is only indirectly possible via nodes capable of redundancy (e.g. SCALANCE X-400).
This applies to all SCALANCE X-100 media converters.

Figure 3-4 Example of a standby coupling of two redundant rings

You can connect two media converters of the same type in series, i.e. connect them to each
other via the FO port. Both media converters must be operated in Transparent Link Mode for the
cascade. You enable Transparent Link Mode using the SET button. For more information, refer
to "SET button (Page 27)".
In Transparent Link Mode, both media converters communicate via a specific protocol. With
this protocol, the media converters initially exchange the link information present at the
electrical RJ45 ports between one another. The transmission leads to a certain delay in the
behavior for establishing the link at the electrical ports. This can cause a timeout at the

Network topologies
Ethernet interface for devices that are electrically connected and the link is not established.
This behavior cannot be influenced and occurs particularly when plants are switched on.
Use the new SCALANCE XCM102 media converters with corresponding SFPs for such
applications.
Note the following restrictions:
• A maximum of two media converters can be connected in series.
• Mixed cascading of SCALANCE X-100 media converters and OMC media converters is not
possible.
• Mixed operation of SCALANCE X101-1/X101-1LD with SCALANCE XCM102 is not possible.
• Cascading is only permitted via the connection of the FO ports.
• Cascading must be set on both media converters using the SET button (transparent link LED
lights up). Otherwise, there may be functional disruptions.
• The setting remains after cycling power.
• When shipped, the standalone mode is enabled; in other words no cascading.

Description of the device 4
4.1 Purpose
What is possible?
The media converters of the SCALANCE X-100 allow the cost-effective installation of Industrial
Ethernet linear (bus) and star structures with transitions from one media to another.
The passive use of two identical SCALANCE X-100 media converters in series (cascaded)
within a redundant ring is possible. In this case, the media converters behave "like a section
of cable". A simple, passive coupling of two rings is also possible. See also "Coupling of
network segments (Page 13)".
Note
If devices are supplied over long 24 V power supply lines or networks, measures are necessary
to prevent interference by strong electromagnetic pulses on the supply lines. These can result,
for example, due to lightning or switching of large inductive loads.
One of the tests used to attest the immunity of these devices to electromagnetic interference is
the "surge immunity test" according to EN 61000-4-5. This test requires overvoltage protection
for the power supply lines. A suitable device is, for example, the Dehn Blitzductor BVT AVD 24 V
type no. 918 422 or a comparable protective element.

Note
Permitted cable lengths
TP cords or TP-XP cords with a maximum length of 10 m can be connected to the TP port with
the RJ-45 jack.
With the IE FC cables and IE FC RJ-45 plugs 180, an overall cable length of a maximum of 100 m
is permitted between two devices depending on the cable type.
Autonegotiation
With the autonegotiation mechanism, repeaters and end devices can automatically determine
the transmission speed and the transmission mode of the partner port. This makes it possible to
configure different devices automatically.

4.5 FO port (fiber optic)
Two components connected to a link segment can exchange information about the data
transfer and can adapt their settings to each other. The mode with the highest possible speed
is set.
Note
Devices not supporting autonegotiation must be set permanently to 100 Mbps half duplex or
10 Mbps half duplex.
Auto polarity exchange

If the pair of receiving cables is connected incorrectly (RD+ and RD- interchanged), the polarity
is adapted automatically.
MDI / MDI-X autocrossover function

With the MPI/MDI-X autocrossover function, the send and receive contacts of an Ethernet port
are assigned automatically. The assignment depends on the cable with which the
communications partner is connected. This means that it does not matter whether the port is
connected using a patch cable or crossover cable. This prevents malfunctions resulting from
mismatching send and receive lines. This makes installation much easier for the user.
The SCALANCE X-100 media converters all support the MDI / MDI-X autocrossover function.
NOTICE
Failure of the data traffic due to contamination of optical plug-in connections
Optical sockets and plugs are sensitive to contamination of the end face. Contamination can
lead to the failure of the optical transmission network. Take the following precautions to avoid
functional impairments:
• Clean the end face of field-assembled connectors carefully before connecting. No residues
of processing may remain on the connector.
• Only remove the dust caps of optical transceivers and pre-configured cables shortly before
connecting the cables.
• Close unused optical sockets and plugs as well as pluggable transceivers and slots with the
supplied protective caps.

NOTICE
No link building with active plug-in transceivers
If you connect a SCALANCE X101-1 or SCALANCE X101-1LD media converter to the port of a
partner device in which an active plug-in transceiver is plugged in, the media converter does
not establish a link.
The SCALANCE X101-1 and SCALANCE X101-1LD media converters are not compatible with
the following plug-in transceivers:
• SFP991-1A (6GK5991-1AD00-8GA0)
