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.
Upon removal of the product, ensure that the protective earthing
conductor is disconnected last.

when connected to a power supply.
WARNING - PROTECTIVE FUSE
The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply.
Ensure compliance to national installation regulations.
This product has no internal fuse and should be connected via an
external fuse for protection.
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.

66641-2201
CAUTION - HOT SURFACE

Description
Functional description
Viper-408 is a switch 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 reconfigure
a network in the event of any failure of a link or hardware. Real-time properties are
implemented in order to achieve determinism for real time critical applications. Viper-
408 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 semiconductor
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.

IP configuration
Configuration
The units can easily be configured via the onboard Web based configuration tool. Local IP
addresses can also be configured by using the Westermo IP Configuration tool, from the
IP Configuration tool it is then possible to browse into the unit for 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 network it is possible to access
the unit directly from a web browser.
Change local IP address
The local address of Viper can be configured using the IP Configuration tool, then it is
possible to browse into the unit for further configuration. The IP Configuration program
is available on the CD or for download from the Westermo web page: http://www.
westermo.com, choose Downloads/Software/Ethernet/Ethernet switches Name: IP config
Westermo.zip
Install the software and start the application from a PC on the network connected to
the same network as the Viper. Make sure that the Default IP of the configuration
software (see figure below) is in the same subnet as your PC.
Figure 1
NOTE
If you are not sure about the subnet – consult your network
administrator. IP Config version must me 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
asked if you would like to access via web figure 2. Click the abort button,
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).

Click the Scan for switches button again and the settings you configured will appear in the list.
Now you can access the Viper via the browser for further configuration by clicking the unit with
an IP address that fits your subnet. Figure 2 will appear and when you click the OK button and a
web browser will be opened and redirected to the Viper unit log in page (see figure 5).

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.
