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. Refer to Specific Conditions of Use.
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).
"Note that this unit can be connected to two different power sources."
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.
When this unit is operated at an ambient temperature above +60°C (+140°F),
forced ventilation is required to not exceed Touch Temperature Limits according
to UL/IEC/EN 60950-1. A recommended airflow 32CFM (61m3/h) located 17cm
(7") below the unit is a minimum requirement. To reduce the risk of fire, use only
No. 26 AWG or larger telecommunication line cord.
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.

Description
Functional description
The Wolverine DDW-142 allows effec tive Ethernet networks to be created over long
distances up to 15 km (9.3 mi) at data rates up to 15.3 Mbit/s on a single twisted pair
cable. By using two pairs “bonded” this rate can be doubled up to 30.4 Mbit/s. The integral
switch allows 2 Ethernet devices to be attached and an RS-232 port allows for a legacy
piece of equipment to be incorporated into the IP network.
The operating system in DDW-142 (WeOS) can deliver unique security functionality for
this class of product as well as allowing the DDW-142 to form part of a resilient multimedia ring network using the Westermo FRNT protocol or industry standard STP/RSTP.
WeOS has been developed to provide industrial networking solutions and contains amazing serial connectivity capability – from being able to simulate an old AT modem, convert
Modbus RTU to TCP or encapsulate serial data into an IP packet.
The DDW-142 is incredibly flexible and easy to use. A basic point to point or multidrop
network can be created without the need for any kind of configuration. If however a more
complex solution requires some kind of network configuration the Web based setup is
simple to use. A CLI interface is also provided making the unit easy for networking professionals to quickly master. Once the system is configured an easy solution is also available for the maintenance engineer – USB backup and restore means that stored configurations can be automatically downloaded from a USB stick.
The DDW-142 is often used in applications on railways, roads or with utilities where failure could result in significant costs. All Westermo products are designed with high MTBF
in mind to improve operational reliability and also give long service life. Even features
like the SHDSL diagnostics and management allow indication of line degradation allowing
planned main tenance. As the unit is designed for these applications Westermo also ensure
that testing is carried out to ensure the unit can operate at extremes of temperature,
EMC and vibration and still provide robust communications.

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.

Cable factory reset on DDW-142
It is possible to set the unit to factory default settings by using a standard Ethernet RJ-45
cable.
1. Power off the unit and disconnect all cables.
2. Connect an Ethernet cable between Ethernet ports 1 and 2.
The unit needs to be connected directly by an Ethernet cable i.e., not via a hub or switch.
Use a straight cable – not a cross-over cable, when connecting the ports.
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 the
Ethernet cable. The ON LED will stop flashing.
This initiates the factory reset process*, and the unit will restart with factory default
settings. When the switch has booted up, the ON LED will show a green light, and is
now ready to use.
• 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 the Ethernet cable.
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.
