!

Before installation:

Read this manual completely and gather all information on the unit. Make sure that
you understand it fully. Check that your application does not exceed the safe oper­ating specifications for this unit.

This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is

restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be

possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.

This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).

Before mounting, using or removing this unit:

Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.

Care recommendations

Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.

This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause

damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-

proof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical

part may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo dis-

tributor office or Westermo Tech support.
A readily accessible disconnect device shall be incorporated external to the equipment.
This unit may have hot surfaces when used in high ambient temperature.

WARNING:

When this unit is operated at an ambient temperature above +60°C, the External Surface
of Equipment may exceed Touch Temperature Limit according to EN/IEC/UL 60950-1.

Maintenance

No maintenance is required, as long as the unit is used as intended within the specified
conditions.

than mines susceptible to firedamp.

Equipment category 3.
A category is the classification according to the required level of protection.
This unit ensures the requisite level of protection during normal operation and
is intended for use in areas in which explosive atmosphere caused by gases,
vapours, mists, or dust mixtures are unlikely to occure or, if they do occure, are
likely to do so only infrequently and for a short periode only.

Indicates protection concerning explosive atmospheres caused by gases,
vapours or mists (G).

The type of protection used.

Description

DDW-226 is an Ethernet extender with integrated switch and support for legacy serial
connections. It uses the Westermo WeOS operating system that provides the DDW­226 with all the advanced switching and routing functionality supported by the DDW-

226. These functions include VLAN support, Layer 2/3 switching, Static Routing, Firewall
functions, IGMP Snooping, VPN support.

A further enhancement the DDW-226 provides is a set of advanced diagnostic functions
that allow the SHDSL line to be dynamically monitored allowing alarms to be config­ured to pre-warn of any performance issues. This monitoring data can be accessed in a
number of ways; it can be read at any time through the Web Interface, Command Line
Interface or via SNMP.

A key function of the DDW-226 is its ability to be used to create redundant ring net­works over the SHDSL links, using both the Westermo FRNT protocol, but also RSTP.

Mounting

Mounting, 35 mm DIN-rail

The unit can be mounted on a 35 mm DIN-rail, which is
horizontally mounted inside an apparatus cabinet, or similar.
Snap on mounting, see figure.

Note! For proper vibration and chock performance
Westermo recommends standard top-hat DIN-rail TH 35-15
according to EN 60715.

Removal

Press down the support at the back of the unit using
a screwdriver. See figure.

Wall mounting

This unit can also be wall-mounted, see figure.

CLICK!

Earth connection

For correct function the ground connection on the unit
needs to be properly connected to a solid ground.
See figure.

Cooling

This unit uses convection cool­ing. To avoid obstructing the
airflow around the unit, use the
following spacing rules. Minimum
spacing 25 mm (1.0 inch) above
/below and 10 mm (0.4 inches)
left /right the unit.
Spacing is recommended for the
use of unit in full operating tem­perature range and service life.

Getting Started

This product runs Westermo Operating System (WeOS) which provides several
management tools that can be used for configuration of the unit.

• IPConfig tool

This is a custom Westermo tool used for discovery of attached Westermo units.

• Web

Configuration of the unit using the web browser.

• CLI
Configuration of the unit via the Command Line Interface.

If the computer is located in the same subnet as the switch you can easily use a web
browser to configure the unit. Within the web you can configure most of the available
functions.

For advanced network settings and more diagnostic information, please use the CLI.
Detailed documentation is available in the chapter ”The Command Line Management
Tool” in the WeOS management guide.

Factory default IP address: 192.168.2.200
Netmask: 255.255.255.0
Gateway: Disabled

Note! If you are not sure about the subnet – consult your network administrator.

Configuration

Configure the unit via Webbrowser

The unit can easily be configured via a Web browser.
Open the link http://192.168.2.200 in your web browser, and you will be prompted with
a Login screen, where the default settings for Username and Password are:

Username: admin
Password: westermo

Once you have logged in, you can use the extensive integrated help function describing
all configuration options. Two common task when configuring a new switch is to assign
appropriate IP settings, and to change the password of the admin account.
The password can be up to 64 characters long, and should consist of printable ASCII
characters (ASCII 33-126); 'Space' is not a valid password character.

Note! Version of IP Config tool must be 10.3.0 or higher.

RJ-45 cables.

1. Power off the switch and disconnect all Ethernet cables and DSL cables.

2. Connect one Ethernet cable between Ethernet port 1 and Ethernet port 4, and
another Ethernet cable between Ethernet port 2 and Ethernet port 3.
The ports need to be connected directly by Ethernet cables, i.e., not via a hub or
switch. Use straight cables – not cross-over cables – when connecting the port pairs.

3. Power on the unit.

4. Wait for the unit to start up. Control that the ON LED is flashing red.
The ON LED flashing indicates that the unit is now ready to be reset to factory
default. You now have the choice to go ahead with the factory reset, or to skip
factory reset and boot as normal.

• Go ahead with factory reset:

Acknowledge that you wish to conduct the factory reset by unplugging one of the
Ethernet cables. The ON LED will stop flashing.
This initiates the factory reset process*, and after approximately 1 minute the unit
will restart with factory default settings. When the switch has booted up, the ON
LED will typically show a green light (a red light is shown if only one of the DC
power feeds is connected).

• Skip the factory reset:

To skip the factory reset process, just wait for approximately 30 seconds
(after the ON LED starts flashing RED) without unplugging any of the Ethernet
cables. The switch will conduct a normal boot with the existing settings.

* Note Do not power off the unit while the factory reset process is in progress.
