2.2 Product properties
Possible applications of the SCALANCE W786
The SCALANCE W786 is equipped with an Ethernet port and up to three wireless LAN ports.
This makes the device suitable for the following applications:
● The SCALANCE W786 forwards data within its transmission range from one node to
another without a connection to wired Ethernet being necessary.
● The SCALANCE W786 can be used as a gateway from a wired to a wireless network.
● The SCALANCE W786 can be used as a wireless bridge between two networks.
● The SCALANCE W786 can be used as a bridge between two cells operating at different
frequencies.
With a SCALANCE W786 with more than one WLAN port, you can also implement a
redundant wireless connection to a SCALANCE W78x with at least two WLAN ports.
Properties of the SCALANCE W786
● The Ethernet interface supports 10 Mbps and 100 Mbps, both in full and half duplex as
well as autocrossing and autopolarity.
● Operating the wireless interface in the frequency bands 2.4 GHz and 5 GHz.
● The wireless interface is compatible with the standards IEEE 802.11a, IEEE 802.11h,
IEEE 802.11b and IEEE 802.11g. In the 802.11a, 802.11h and 802.11g mode, the gross
transmission rate is up to 54 Mbps. In turbo mode, the transmission rate is up to 108
Mbps (not permitted in all countries and modes).
● As an expansion of the 802.11a mode, it is also possible to operated according to the
IEEE 802.11h standard. In 802.11h mode, the procedures Transmit Power Control (TPC)
and Dynamic Frequency Selection (DFS) are used in the range 5.25 - 5.35 and 5.47 -
5.75 GHz. In some countries, this allows the frequency subband of 5.47 - 5.725 GHz to
be used outdoors even with a higher transmit power.
TPC is a technique of controlling the transmit power by reducing it to the strength actually
required. With dynamic frequency selection (DFS), the access point searches for primary
users (for example radar) on a randomly selected channel before starting communication.
If signals are found on the channel, this channel is disabled for 30 minutes and the
availability check is repeated on another channel.
● Support of the authentication standards WPA, WPA-PSK, WPA2, WPA2-PSK and
IEEE 802.1x and the encryption methods WEP, AES and TKIP.
● Suitable for inclusion of a RADIUS server for authentication.
● Device-related and application-related monitoring of the wireless connection.
● The interoperability of SCALANCE W786 devices with Wi-Fi devices of other vendors
was tested thoroughly.
Note
In client mode, you can use a SCALANCE W786-xPRO with the functionality of a
SCALANCE W746-1PRO.

Flashing red Ready to load firmware. The device was either stopped with the reset
button or there is incorrect firmware on the device.
Note
If the LED for the WLAN port is not green when the device starts up, although it is activated,
the port is not ready for operation (interface not initialized).
The main reason for this is usually that during commissioning of the SCALANCE W78x
products, a waiting time of up to 15 minutes can occur when the ambient temperature is
below zero. The device is ready for operation at the specified ambient temperature as soon
as the LED for the WLAN interface is lit green.

2.4 C-PLUG

16 Operating Instructions, ,
2.4 C-PLUG
Configuration information on the C-PLUG
The C-PLUG is used to transfer the configuration of the old device to the new device when a
device is replaced. When the new device starts up with the C-PLUG, it then continues
automatically with exactly the same configuration as the old device. One exception to this
can be the IP configuration if it is set over DHCP and the DHCP server has not been
reconfigured accordingly.
Reconfiguration is necessary if you use WDS or redundancy and use the MAC addresses
and not the sysNames. These functions are then based on the MAC address that inevitably
changes if a device is replaced.
Note
As soon as the device is started with a C-PLUG inserted, the SCALANCE W-700 starts up
with the configuration data on the C-PLUG.

2.6 Biological compatibility
Electromagnetic fields and health
With regard to the question of whether electromagnetic fields (for example in association
with industrial wireless LANs) can put human health at risk, we refer to a publication of
BITKOM (German Association for information Technology, Telecommunication and New
Media e. V.), dated December 2003:
"The same health guidelines apply to WLAN devices as to all other radio applications. These
regulations are based on the protection concept of ICNIRP1 or the corresponding
recommendation of the European Council.
The independent German radiation protection commission (SSK) was commissioned by the
federal German ministry of the environment to investigate the possible dangers - thermal and
non-thermal - resulting from electromagnetic fields and came to the following conclusions2:
'The German Commission on Radiological Protection concludes that according to the latest
scientific literature no new scientific research is available with respect to proven health
hazards which would throw doubt upon the scientific evaluation which serves as the basis for
the ICNIRP safety concepts and the recommendations of the EU commission.'
The SSK also concludes that below the current limit values, these is also no scientific
suspicion of health risks.
This assessment agrees with those of other national and international scientific commissions
and of the WHO (www.who.int/emf).

RSS-210 of Industry Canada
"Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference that
may cause undesired operation of the device."
"This device has been designed to operate with the antennas listed below, and having a
maximum gain of 18 dBi. Antennas not included in this list or having a gain greater than 18
dBi are strictly prohibited for use with this device. The required antenna impedance is 50
ohms."
"To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
permitted for successful communication."
"That the device for the band 5150-5250 MHz is only for indoor usage to reduce potential for
harmful interference to co-channel mobile satellite systems."
"Users should also be cautioned to take note that high power radars are allocated as primary
users (meaning they have priority) of 5250-5350 MHz and 5650-5850 MHz and these radars
could cause interference and/or damage to LE-LAN devices."
