8 Description Designed for harsh industrial environments The Viper-12A series is a series of managed 12 port switches optimised for the needs of the railway rolling stock market. Gbps ports cope with high bandwidth devices such as access points and NVRs (Network Video Recorders). The Viper is designed to withstand the tough environment on-board trains, exposing the switch to constant vibration, extreme temperatures, humidity and a demanding electrical environment. A GORE-TEX membrane prevents internal condensation. Threading integrated in chassis provides for additional vibration resistance. High-level isolation between all interfaces enables direct connectivity to vehicle auxiliary power and protects against overvoltage and flashover. IP67 protection prevents ingress of water and dust. An overall optimised design results in an extremely compact package in combination with very high MTBF for easy integration and low lifecycle cost. Thorough type testing at independent labs certify the compliance to a wide range of standards, not least EN 50155, where the highest class is achieved in all aspects. The state-of-the-art Westermo production facility ensures the quality of each individual unit, e.g. through temperature cycling burn-in testing. The WeOS operating system offers an extensive suite of IP networking features for resilient and flexible networks, e.g. the FRNT ring protocol with very fast failover on 100 Mbps as well as Gbps ports. The powerful layer 3 routing capability is very useful for separating networks in complex applications. The backup device accessory matches the Viper in robustness and offers easy configuration update and backup. Meeting the requirements of the railcar market, the Viper is very well suited for deployment in any other application with severe operating conditions and tough environments, for instance in the mining industry. Product models All switches are managed. Viper x12a is used when referring to both models 112A and 212A.

16 Getting started This product runs Westermo Operating System (WeOS) which provides several management tools that can be used for configuration of the unit. WeConfig WeConfig is a Network configuration management tool (NCM) made for commissioning and maintenance of components in a network. 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: (and DHCP client) Netmask: 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 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 ); 'Space' is not a valid password character

17 Reference documents Type Description Document number Management Guide Westermo OS Management Guide Cable 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 X5 and X10 and the other between Ethernet ports X6 and X9. 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. Check 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 one of the Ethernet cables. The ON LED will stop flashing. This initiates the factory reset process, and the unit will restart with factory default settings. 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 any of the Ethernet cables. The switch will conduct a normal boot with the existing settings
