Safety information
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 cooling.
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 EN 45545-2 mounting notes.
The unit has no internal fuse and should be connected via an external fuse. The fuse
should be calculated in accordance with the rated current.
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.
Be aware of that the surface of this unit may become hot. When this unit is
operated at high temperatures, the External Surface of Equipment may exceed
Touch Temperature Limit according to EN/IEC/UL 60950-1.
To reduce the risk of fire:
1. Use only No. 21 AWG or larger power cable

Description
Functional description
Viper is a range of switches consisting of two different function levels developed for
rail and industrial applications. To meet the environmental requirements from rail and
harsh industrial applications the switch has rugged M12 Ethernet connectors and full
metal housing. The switch fullfill IP65 degree of protection when all ports are protected/
connected. Our unique FRNT (Fast Recovery of Network Topology) technology is the
fastest protocol on the market to re-configure a network in the event of any failure of a
link or hardware. Real-time properties are implemented in the Viper108 and 408 in order
to achieve determinism for real time critical applications. The Viper-switches supports
QoS (Quality of Service) with four priority queues and strict priority scheduling as
well as HoL (Head of Line Blocking Prevention). All to assure that the data network is
deterministic.

Fault Contact
The Viper switch is equipped with a potential free normally closed fault contact.
The fault contact is a solid state component (relay) that requires power to work and it
is transient protected. Additionally, the fault contact is opened when any of the following
conditions is met:
• No voltage on the power supply pin, a voltage level outside the legal voltage range
or current limitation on the voltage source is applied on the power input.
• Link alarm i.e. missing link on any Ethernet port that has link alarm enabled.
• Redundancy Mode activated i.e. one or more FRNT link is down.
Description of how connection to the fault contact could be done is shown below.
The relay is closed when the unit is OK and open at failure. The relay is of semiconduc-
tor type (no moving parts). It is specified for max current 250 mA continuous,
500 mA peak (10 ms), operational voltage up to 110 V, protected by a 150 VDC-varistor,
ON-resistance less than 10 Ohm, and leakage current max 1 µA.

Configuration
The units can easily be configured via the ononard Web based configuration tool. Local IP
addresses can also be configured by usinn the Westermo IP Configuration tool, from the
IP Configuration tool it is then Enssible to browse into the unit fnr further configuration.
IP Address
When delivered, the default IP address of the Viper is 192.168.2.200.
Default gateway 192.168.2.200
If the default address of the unit is valid in the connected netwnrk it is Enssible to access
the unit directly from a web browser.
Change local IP address
The local address of Viper can be configured usinn the IP Configuration tool, then it is
Enssible to browse into the unit fnr further configuration. The IP Configuration program
is available on the CD nr fnr download from the WESTERMO web pane:
http://www.westermo.com, chonse Downloads/Software/Ethernet/Ethernet switches
Name: IP config Westermo.zip
Install the mnftware and start the application from a PC on the netwnrk connected to
the same netwnrk as the Viper. Make sure that the Default IP of the configuration mnft-
ware (see figure below) is in the same subnet as ynur PC.
Note! If ynu are not sure abnut the subnet – consult ynur netwnrk administratnr.
Note! IP Config version must be 10.0.0 or higher.

By clicking the “Scan for Devices” button the IP Configuration tool will detect the
switches/routers in the network. The software will list all Westermo managed switches
or routers connected to the network. Information as in the figure 1 will appear for each
detected unit connected to the same network as your PC.
If you only want to change the IP address and the subnet mask, this
can be done within the IP config tool.
By clicking the listed Viper that you wish be re-configured you will be

enter the preferred IP address, Subnet mask and IP gateway address and
click the Set button to confirm the settings in the unit (see figure 3).
Note! If you are not sure about the settings – consult your network administrator.

Factory Reset
The factory reset option restores the switch to its original factory condition.
The switch will be restored using the following settings.
• IP address 192.168.2.200
• Subnet mask 255.255.255.0
• Gateway 192.168.2.1
• All Ethernet ports are enabled and set to Auto Negotiate
• All applications are disabled
• Password reset to westermo
To perform a Factory Reset follow the procedure below. Read all steps before
starting. If you have any doubts whether the reset is performed or not, do
NOT unplug the power supply, wait for confirmation according to step 5.
1. Disconnect the power
2. Connect cables between port x1-x6 and port x2-x5.
3. Apply power
4. Wait for approx imately 90 seconds. (Some LED will flash during start up
5. When the Green LED's on all Ethernet ports are constantly on, then remove the
cables connected to port x1-x6 and x2-x5.
6. It is now safe to remove the power and restart the switch.
7. When the switch has started up it will have the default settings.
NOTE! If the power is removed before the factory reset has finished,
the switch may be come unusable.
