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 fulfills 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. Viper408 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 are 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.
A description of how the 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.

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.
If you are not sure about the subnet – consult your network administrator. 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 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 to be re-configured you will be asked if you would like to access it via the 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).
If you are not sure about the settings – consult your network administrator.
Click the Close button to get back to the main view. You will then be asked if you would like to quit. Click the OK button, figure 4, and you will be back to the main view of the IP Configuration program(see figure 1).
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).
Log in via Web
You will be prompted with a Login screen where
the default settings for Username and Password are:
Username: admin

Mounting
There are four 6 mm boreholes intended for mounting the unit. The unit can be mounted vertical or horizontal. The unit is wall mounted.
Removal
Disconnect all cables and unscrew the unit from the wall.
Cooling
This unit uses convection cooling. Avoid obstructing the airflow around the unit. Spacing is recommended for the use of the unit in the full operating temperature range and service life.
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 about whether the reset is performed or not, do NOT unplug the power supply, wait for confirmation according to step 5.
- Disconnect the power
- Connect cables between port x1-x6 and port x2-x5.
- Apply power
- Wait for approximately 90 seconds. (Some LEDs will flash during start-up
- When the Green LED’s on all Ethernet ports are constantly on, then remove the cables connected to ports x1-x6 and x2-x5.
- It is now safe to remove the power and restart the switch.
- When the switch has started up it will have the default settings.
If the power is removed before the factory reset has finished, the switch may become unusable.
Dimensions
Measurements are stated in millimeters.
