Before installation:
Read this manual completely and gather all information on the product. Make sure that you understand it fully. Check that your application does not exceed the safe operating specifications for this product.
WARNING – SAFETY DURING INSTALLATION
The product must be installed by qualified service personnel and built in to an apparatus cabinet or similar, where access is restricted to service personnel only.
During installation, ensure a protective earthing conductor is first connected to the protective earthing terminal (only valid for metallic housings). Westermo recommends a cross-sectional area of at least 4 mm2.
If the product does not have a protective earthing terminal, then the DIN-rail must be connected to protective earth. Upon removal of the product, ensure that the protective earthing conductor, or the connection to earth via the DIN-rail, is disconnected last.
WARNING – HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur when connected to a power supply.
WARNING – PROTECTIVE FUSE
It must be possible to disconnect manually from the power supply. Ensure compliance to national installation regulations. Replacing the internal fuse must only be performed by Westermo qualified personell.
WARNING – REDUCE THE RISK OF FIRE
To reduce the risk of fire, use only telecommunication line cords with a cable diameter of AWG 26 or larger. Regarding power cable dimensions, see Interface Specifications.
CAUTION – ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damages to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).
CAUTION – HOT SURFACE
Be aware of that the surface of this product may become hot. When it is operated at high temperatures, the external surface may exceed Touch Temperature Limit according to the product’s relevant electrical safety standard.

Description
DDW-225 is a part of the Wolverine family of Ethernet extenders. It uses the WeOS operating system that provides the DDW-225 with all the advanced switching and routing functionality supported by the DDW-225. These functions include VLAN support, Layer 2/3 switching, Static Routing, Firewall functions, IGMP Snooping, VPN support. A further enhancement the DDW-225 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-225 is its ability to be used to create redundant ring networks over the SHDSL links, using both the Westermo FRNT protocol, but also RSTP.
- Up to 15.3 Mbit/s over old cables
- Redundant ring on the SHDSL interface
- Advanced Diagnostics
- VLAN support and IGMP Snooping
- VPN support

Mounting
Mounting, 35 mm DIN-rail
The unit can be mounted on a 35 mm DIN-rail, which is horisontally 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.
Earth connection
For correct function the ground connection on the unit needs to be properly connected to a solid ground.
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 web browser
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.

Factory default on DDW-225
It is possible to set the unit to factory default settings by using two standard Ethernet RJ-45 cables.
- Power off the switch and disconnect all Ethernet cables and DSL cables.
- 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.
- Power on the unit.
- 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.
