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 all power
supply. Ensure compliance to national installation regulations. This unit relies on
convection heating. Make sure that it is installed so that the ambient temperature
is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit. Also check chapter CEN/TS 45545-2 mounting notes.
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from all power supply.
WARNING
Do not open connected unit. Hazardous voltage may occur within this unit when
connected to power supply.
Before powering-up, a protective earthing conductor must be connected to the
protective earthing terminal and have a cross-sectional area of at least 1.5 mm².
Note that this unit can be connected to two different power sources.
When this unit is operated at an ambient temperature above +60°C (+140°F), the
External Surface of Equipment may exceed Touch Temperature Limit according to
EN/IEC/UL 60950-1. To reduce the risk of fire, use only No. 26 AWG or larger
telecommunication line cord.

Description
Designed for harsh industrial environments
The Viper-12-PoE series is a series of managed rugged Ethernet switches with Power
over Ethernet, designed for applications with severe operating conditions and extreme
environments.
With an ultra robust design, sealed to IP67 and vibration resistant to and exceeding
on-board rail standards these units are ideal for situations where mechanical stress,
moisture, condensation, dirt or continuous vibrations could adversely affect the function
of standard Ethernet switches. Fully approved for onboard rolling stock, these units can
be deployed in e.g. trains, trams, busses, mining trucks, army vehicles and drilling rigs.
Features for complete network management
Our unique FRNT technology is the fastest and most robust protocol on the market
to re-configure a large network in the event of any link or hardware failure. The Viper12-PoE series also supports STP/RSTP in case of need for standard protocol. IGMPv2/
v3 with stop filter and the unique Westermo protocol ’Fast Reconnect’ allows a video
stream to reconfigure very fast. Advanced functionality for VLANs with support for up
to 64 virtual networks, combined with real-time properties is implemented in the switch
in order to achieve determinism for real time critical applications.
Made easy and secure configuration
You can safely access your switch from anywhere in the network, or directly to the
product via a console port. The HTTPS secured web configuration interface has been
designed ’Made Easy’, setting up a redundant ring or a VLAN is just a few clicks away. For
more advanced configuration, you will find an SSH encrypted industry standard CLI which
allows extremely detailed settings. For safe handling and MIB readout the switch is also
equipped with SNMPv3.
Product models
There are four different models of the Viper-12-PoE series:
3641-0580 Viper-112-P8 managed switch with Layer 2 SW functions.
3641-0590 Viper-212-P8 managed switch with Layer 3 SW functions.
3641-0570 Viper-112-T3G-P8 managed switch with Layer 2 SW functions and three GigE ports.
3641-0595 Viper-212-T3G-P8 managed switch with Layer 3 SW functions and three GigE ports.

(use Westermo cable 1211-2215 to the console port).
2. Connect cable to your computer serial port.
3. Use a terminal emulator and connect with correct speed and format (115200, 8N1)
to the assigned port.
For more information about the CLI, see the WeOS management guide.
Connection to USB port
The USB port can be used to copy configuration and log files to/from the switch.
The following steps needs to be taken
1. Connect the USB plug (use Westermo USB plug 3641-0190) to the USB port.
2. Access the switch CLI (via console cable or SSH)
3. Use the CLI ''copy'' command to copy files between the USB plug and the switch.
For more information about the CLI, see the WeOS management guide.

Connection of cables
Recommended tightening torque for the M12 connectors: 0.6 Nm.
Note that unused connectors must be covered by a protective cap (delivered with the
unit), tightened to the specified torque, in order to fulfill the specified ingress protection
code.
Removal
Disconnect all cables and unscrew the unit from the wall.
Time For Replacement < 15 minutes
Cooling
This unit uses convection cooling. Avoid obstructing the airflow around the unit. Spacing
is recommended for the use of unit in full operating temperature range and service life.
CEN/TS 45545-2 mounting notes
Two Viper units can be mounted together and as a single interior non-listed group in the
sense of CEN/TS 45545-2 definitions. For multiple units the spacing requirements for
interior non-listed groups must be met.

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.
Note! Version of IP Config tool must be 10.4.0 or higher.
• 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

Factory reset
It is possible to set the unit to factory default settings by using two standard Ethernet
M12 cables.
1. Power off the switch and disconnect all Ethernet cables.
2. Connect one Ethernet cable between Ethernet ports X1 and X6, and the other
between Ethernet ports X2 and X5. The ports need 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
cables. The ON LED will stop flashing.
This initiates the factory reset process*, 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 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.
