Preface
Biological Compatibility
The question as to whether electromagnetic fields (for example in connection with
high-frequency mobile radio) can be detrimental to human health is taken seriously
by Siemens. The protection of the population, customers and employees is of major importance and must come before commercial interest.
The products are subject to and comply with the currently valid limit values recommended on the basis of numerous scientific studies. These limit values are well below the field strengths that must be exceeded before their effects are considered
relevant to health.
The products are assessed by authorized official bodies. If these limit values are
adhered to, risk of damage to health can be excluded according to the opinion of
independent scientific committees and the current state of knowledge.
Today's wireless LAN systems are significantly below these required limit values.
Wireless LAN systems have a maximum power output of 0.1 W, while the output
power of a commercial mobile phone is up to 2 W.
Notes on Working with Wireless LAN Products
When working with wireless LAN products, you may find the following notes helpful:
● Restrict exposure to high-frequency electromagnetic fields to a minimum time
and amount
● Obtain regular information on the latest state of the technology, available in literature from Siemens A&D
● Show particular consideration to people with sensitive health including children
and adolescents
● Show particular consideration to persons with heart pacemakers and hearing
aids
Maintain a minimum clearance of 0.5 m between antennas and people whenever
possible. This does not imply that clearances less than this distance will lead to
impairment of health.

Basic Information on Wireless LAN
Communication
1.1
Network Structure
Ad Hoc Networks
In the ad hoc mode, nodes communicate directly with the server (connections 1
through 3 in the graphic below) without involving a SCALANCE W 788 or with each
other (connection 4). The nodes access common resources (files or even devices,
for example a printer) of the server. This is, of course, only possible when the
nodes are within the wireless range of the server or within each other's range.

Basic Information on Wireless LAN Communication
Standalone Configuration with the SCALANCE W 788
This configuration does not require a server and the SCALANCE W 788 does not
have a connection to a wired Ethernet. Within its transmission range, the
SCALANCE W 788 forwards data from one WLAN node to another.
The wireless network has a unique name. All the devices exchanging data within
this network must be configured with this name.

Basic Information on Wireless LAN Communication
Wireless Access to a Wired Ethernet Network
If one (or more) SCALANCE W 788 access points have access to wired Ethernet,
the following applications are possible:
● A single SCALANCE W 788 as gateway:
A computer equipped only with an Ethernet adapter can be integrated in the client mode in a wireless network over the SCALANCE W 788-1pro.
● Span of wireless coverage for the wireless network with several
SCALANCE W 788 access points:
The SCALANCE W 788 access points are all configured with the same unique
SSID (network name). All nodes that want to communicate over this network
must also be configured with this SSID.
If a mobile station moves from the coverage range (cell) of one
SCALANCE W 788 to the coverage range (cell) of another SCALANCE W 788,
the wireless connection is maintained (this is called roaming).

C79000-G8976-C184-01
Basic Information on Wireless LAN Communication
Multichannel Configuration
If neighboring SCALANCE W 788 access points use the same frequency channel,
the response times are longer due to the collisions that occur. If the configuration
shown in Figure 1-4 is implemented as a single-channel system, computers A and
B cannot communicate at the same time with the SCALANCE W 788-1pro access
points in their cells.
If neighboring SCALANCE W 788 access points are set up for different frequencies, this leads to a considerable improvement in performance. As a result, neighboring cells each have their own medium and the delays resulting from time-offset
transmission no longer occur.
Channel spacing should be as large as possible; a practical value would be 25
MHz (five channels). Even in a multichannel configuration, all SCALANCE W 788
access points can be configured with the same network name.

Wireless Distribution System (WDS)
WDS allows direct connections between SCALANCE W 788 access points. These
are used to create a wireless backbone or to connect an individual
SCALANCE W 788 to a network that cannot be connected directly to the cable infrastructure due to its location.
Two alternative configurations are possible. The WDS partner can be configured
both using its name and its MAC address.

Possible Applications of the SCALANCE W 788
The SCALANCE W 788 is equipped with an Ethernet interface and a wireless LAN
interface (SCALANCE W 788-2pro: two WLAN interfaces). This makes the device
suitable for the following applications:
● The SCALANCE W 788 forwards data within its transmission range from one
node to another without a connection to wired Ethernet.
● The SCALANCE W 788 is used as a gateway from a wired to a wireless network.
● The SCALANCE W 788 can be used as a bridge between two networks.
Due to its second WLAN interface, the SCALANCE W 788-2pro can also be used
to implement a redundant wireless connection between two SCALANCE W 7882pro devices.
Properties of the SCALANCE W 788
● The Internet interface supports 10 Mbps and 100 Mbps, full duplex and half duplex in both cases.
● The wireless interface is compatible with the standards IEEE 802.11a,
IEEE 802.11b and IEEE 802.11g. In the 802.1a- and 802.1g modes, the transmission rate is up to 54 Mbps.
● Operation in the 2.4 GHz and 5 GHz frequency bands.
● Support of the authentication standards WPA, WPA-PSK and
IEEE 802.1x and WEP, AES and TKIP encryption schemes.
● Suitable for inclusion of a RADIUS server for authentication.
● Device-related and application-related monitoring of the wireless connection.
Ports
The SCALANCE W 788 has the following ports:
● A Harting RJ-45 hybrid socket on the front panel of the housing for connection
of an Ethernet cable and for the power supply (hybrid connector for power over
Ethernet).
● An M12 socket for the power supply.
● Two R-SMA sockets (four R-SMA sockets on the SCALANCE W 788-2pro) for
the attachment of antennas on the sides of the device.
Note
In the version for USA/Canada, two fixed antennas are fitted. On the
SCALANCE W 788-2pro, the antennas of the second wireless card can be
detached. The second wireless card can only be operated at 2.4 GHz

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, it continues with exactly the same configuration as the old device. The only exception to this can be
the IP configuration if it is set over DHCP and the DHCP server has not been reconfigured accordingly.
Replacing the C Plug
Follow the steps below to replace a C Plug in a SCALANCE W 788:
1.
Remove the old SCALANCE W 788 from its mounting and open the sealing
screw on the rear with a coin or broad screwdriver.
2.
Remove the C Plug.
3.
Open the sealing screw of the new device in the same way and insert the C
Plug of the old device.
4.
Replace the sealing screws of both devices.
If a new C Plug is inserted in a SCALANCE W 788-1pro, the configuration stored
locally on the SCALANCE W 788-1pro is saved to the C Plug. If an incorrect C
Plug (for example from another device or a damaged plug) is inserted, the
SCALANCE W 788 signals an error with the red LED. The user then has the

Connectors for the Power Supply and for Ethernet
The SCALANCE W 788 is attached to Ethernet via a hybrid socket on the front of
the housing (position A in Figure 3.1). This port also has contacts for the operating
voltage.
Note
If you do not use the hybrid socket, this must be covered with a protective cap,
otherwise IP65 protection is lost. A suitable protective cap is available as an accessory.
As an alternative or in addition to this, you can also use the M12 socket for the
power supply (position B in Figure 3.1).
You can fit additional antennas to the sides of the SCALANCE W 788-2pro (position C in Figure 3.1).
Note
The distance between a pair of antennas for the first and second WLAN interface
should be at least 0.5 m.
Note
In the version for USA/Canada, two fixed antennas are fitted. On the
SCALANCE W 788-2pro, the antennas of the second wireless card can be detached. The second wireless card can only be operated at 2.4 GHz

Introduction
Initial Assignment of an IP Address
An initial IP address for the SCALANCE W 788 cannot be assigned using Web
Based Management or the Command Line Interface because these configuration
tools require that an IP address already exists.
The initial IP address can be obtained over DHCP or assigned using the Primary
Setup Tool. The Primary Setup Tool is capable of assigning such an address to
unconfigured devices without an IP address. The only condition is that the devices
can be reached over Ethernet.
Operating Systems Supported
The Primary Setup Tool can be installed and used with the following operating systems:
● Windows XP Professional
● Windows 2000 Professional SP2
DLC Protocol

Introduction
Principle of Web Based Management
The SCALANCE W 788 has an integrated HTTP server for Web Based Management. If the SCALANCE W 788 is accessed by an Internet browser, it returns
HTML pages to the client computer depending on user input.
Users enter the configuration data in the HTML pages sent by the
SCALANCE W 788. The SCALANCE W 788 evaluates this information and generates response pages dynamically.
The great advantage of this method is that apart from a Web browser, no special
software is required on the client.
Requirements for Web Based Management
Once you have assigned an IP address with the Primary Setup Tool, you can continue to configure the device with Web Based Management.
To use Web Based Management, you should ideally have a wired network connection between the SCALANCE W 788 and the client computer. In principle, it is possible to use Web Based Management over a wireless network, however the
SCALANCE W 788 can be set so that access over a wireless network is disabled.
We recommend that you use the Microsoft Internet Explorer Version 5.5 or higher
or Netscape Navigator Version 6.1 or higher.
All the pages of Web Based Management require JavaScript. Make sure that your
browser settings allow this.
Web Based Management is HTTP-based, so you must also enable access to port
80 if you have a firewall installed.

IP Settings
Description
One of the basic steps in configuration of an Ethernet device is setting the IP address. The IP address identifies a device in the network uniquely. On this page,
you enter the information for IP configuration of the SCALANCE W 788.
Specified IP Address / DHCP Server Option Buttons
There are two methods of assigning IP addresses to devices: The IP address can
be set as a fixed permanent address or can be obtained dynamically from a DHCP
server. Select "Specified IP Address" if you do not use a DHCP server.
IP Address Input Box
The IP address of the SCALANCE W 788. Here, you enter an address that is
unique within the network.

Configuration Using the Wizards of Web Based Management
Subnet Mask Input Box
The subnet mask specifies the range of addresses within which communication
can take place.
The four numbers of an IP address separated by periods are interpreted as a bit
pattern. If a one is set at a bit position within the subnet mask, this means that only
devices with an IP address the matches the IP address of the SCALANCE W 788
at this bit position can communicate with the SCALANCE W 788.
Example
Let us assume that the IP address of the SCALANCE W 788 is set to
192.168.147.189 and the subnet mask is set to 255.255.255.0. The bit pattern for
255 is 1111 1111. This means that the bit pattern of the first number of the IP address of a communication partner must match the bit pattern of the SCALANCE W
788 exactly at this point. The same applies to the second and third parts of the IP
address. The IP address of a communication partner must therefore start with
192.168.147. The bit pattern for 0 is 0000 0000. This means that the bit pattern of
the last part of the IP address of the partner device does not need to match the address of the SCALANCE W 788 at any point; in other words, it can be any number.

Predefined Security Levels
Authentication and encryption are tried and tested methods for increasing security
in networks. Web Based Management provides five predefined security levels that
specify suitable methods. The following table indicates what the various security
levels involve.

Authentication
Authentication basically means that some form of identification is required. In the
case of network communications, authentication methods include those listed below:
● Shared Key
A key must be specified for authentication.
● Authentication according to IEEE 802.1x
The authentication information is located on an external authentication server.
● WPA-PSK (Wi-Fi Protected Access - Preshared Key)
This method is based on a dynamic exchange of keys with the authentication
information being provided by the keywords used.
● WPA (Radius)
Implementation of the WPA method for use of an external radius server.
Encryption
The following schemes are used for data encryption:
● WEP (Wired Equivalent Privacy)
Symmetrical stream cipher (same key for encryption and decryption) with 40 or
104 bit long keys. Modification of the key must be done manually.
● AES (Advanced Encryption Standard)
Symmetrical block encryption scheme with 128, 192 or 256 bit long keys.
● TKIP (Temporal Key Integrity Protocol)
Symmetrical scheme in which new keys are generated cyclically.

6.1.1
Introduction
Contents of This Chapter
Web Based Management provides you with configuration options way beyond
those described in the previous chapter. This chapter explains the possible settings for the SCALANCE W 788. For a detailed description of the individual elements of a page, refer to the online help.
As an alternative, you can also configure the device using the Command Line Interface (CLI). This allows remote configuration over Telnet.
This chapter describes both configuration methods together because the menu
structure of Web Based Management is the same as the structure of the CLI commands.
Required Experience
To be able to use the information in this chapter effectively, you should have a
thorough knowledge of network technology and WLANs.

Display of the Operating State
The SCALANCE W 788 has one or more LEDs that provide information on the operating state of the device (see Chapter 2). Depending on its location, direct access to the SCALANCE W 788 may not always be possible. Web Based Management therefore displays simulated LEDs.
Activating the Simulation
There is an HTML-based simulation of the LED status. Click on the Status Information link to activate the simulation:

console window opens in which you can enter CLI commands directly. The IP address is adopted by Web Based Management and you already entered the logon
data to start WBM.
Shortcuts for Commands
As an alternative, instead of entering full CLI commands, you can simply enter the
first letter or the first few letters and then press the Tab key. The Command Line
Interface then displays a command starting with the letter or letters you typed in. If
the command displayed is not the command you require, press the Tab key again
to display the next command.
Directory Structure
Before you can enter a command in the Command Line Interface, you must first
open the required menu or submenu. This section lists the commands of each
menu in a separate table. The menu itself is shown above the table on a gray
background. The table lists only the commands themselves.

Symbols for Representing CLI Commands
CLI commands generally have one or more parameters that are represented in the
syntax description as follows:
● Mandatory parameters are shown in pointed brackets.
Example:

If you omit a mandatory parameter, most commands output the set value.
● Alternative input values are separated by the pipe character ( | ). In this case,
you specify one of the listed values as the parameter.
Example:

you enter either E or D.
● If a numeric value is required as a mandatory parameter, you can also specify a
range of values:
Example:
<0 ... 255>
You must enter a value between 0 and 255.
