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.
