2.2. 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.
WARNING - 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.
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.
WARNING - HAZARDOUS VOLTAGE
Do not open an energised product. Hazardous voltage may occur when
connected to a power supply.
WARNING - 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.
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.
Viper-8 Series 5

CAUTION - 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 Interface
Specifications.
CAUTION - 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).
CAUTION - 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.
NOTE - MECHANICAL FORCE ON VENTILATION
MEMBRANE
Do not cover or bring mechanical force to the ventilation membrane on
the back of the product.
2.3. Care Recommendations

3. Product Description
3.1. Product Description
The Viper-8 series is a managed backbone routing switch optimised 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 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 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 realtime data protocol. The backup device accessory matches the
Viper in robustness and offers easy configuration update and backup.
