Safety Information
Before installation:
Read this manual completely and gather all information available on the product. Make sure it is fully understood. Check that your application does not exceed the safe operating specifications for the product.
SAFETY DURING INSTALLATION
The product must be installed and operated by qualified service personnel and
installed into an apparatus cabinet or similar, where access is restricted to
service personnel only.
Refer to chapter Compliance Information to see the required level of qualified
service personnel according to safety standards. 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.
HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur when connected to a power supply.
PROTECTIVE FUSE
The power supply wiring must be sufficiently fused. The fuse must be IEC 60127 certified and rated for T1.6 A and 250 V. 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.
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 chapter Interface Specifications.
CABLE TEMPERATURE RATING FOR FIELD TERMINAL WIRES
There may be a requirement on the minimum temperature rating of the cable to be connected to the field wiring terminals, see chapter Interface Specifications.
ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damage to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).
HOT SURFACE
Be aware that the surface of this product may become hot. When it is operated at high temperatures, the external surface may exceed Touch Temperature Limit according to the product’s relevant electrical safety standard.
Care Recommendations
Follow the care recommendations below to maintain full operation of the product and to fulfill the warranty obligations:
- Do not drop, knock or shake the product. Rough handling above the specification may cause damage to internal circuit boards.
- Use a dry or slightly water-damp cloth to clean the product. Do not use harsh chemicals, cleaning solvents or strong detergents.
- Do not paint the product. Paint can clog the product and prevent proper operation.
If the product is used in a manner not according to specification, the protection provided by the equipment may be impaired. If the product is not working properly, contact the place of purchase, the nearest Westermo distributor office or Westermo technical support.
Product Disposal
This symbol means that the product shall not be treated as unsorted municipal waste when disposing of it. It needs to be handed over to an applicable collection point for recycling electrical and electronic equipment. By ensuring the product is disposed of correctly, you will help to reduce hazardous substances and prevent potential negative consequences to both the environment and human health, which could be caused by inappropriate disposal.

Product Description
The Viper-8 series is a managed backbone routing switch optimized for the needs of the railway rolling stock market. Gbps ports cope with high bandwidth backbone, consist ring and end devices. The product 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 optimized 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 ISO/IEC 17025 and ILAC MRA certified labs, accredited to a wide range of standards, show that the Viper series fulfills EN 50155 and other requirements. 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. The powerful layer 3 routing capability ensures communication between the backbone and consist networks and offers full support for IEC 61375, including TTDP network inauguration and TRDP real-time data protocol. The backup device accessory matches the Viper in robustness and offers easy configuration update and backup.

Installation
Wall Mounting
The product can be wall-mounted vertically or horizontally. There are four pieces of 7 mm bores for this. Use four M5, M6 or 1/4″ screws with 12 mm washers on a flat and stable surface.
Protective Earth Connection
For correct function, the earth connection needs to be properly connected to a designated PE rail. See the figure below. Torx: T25 and torque: 3.2 Nm.
Connection of Cables
Recommended tightening torque for the M12 connectors is 0.6 Nm. All M12 connections are screw connections. When connecting the power cable, ensure that the pins are connected correctly before tightening the power cable to the unit.
Cooling
This product relies on convection cooling. Make sure that it is installed so that the ambient temperature is within the specified temperature range. Avoid obstruction of the airflow around the product.
Replacement of Product
Disconnect all cables and unscrew the product from the wall. Mount the replacement product and reconnect all cables, observing the instructions in Connection of Cables [15]. For easy replication of the configuration of the original product, it is recommended to have the Westermo USB plug permanently connected to the USB port and move it over to the replacement product before it is powered up. MTTR (Mean Time To Repair), i.e. time for replacement of product is: < 8 minutes.
EN 45545-2 Mounting Notes
