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.
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. Note that this product can be connected to
two different power sources. 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.
NOTE – MECHANICAL FORCE ON VENTILATION MEMBRANE
Do not cover or bring mechanical force to the ventilation membrane on the back
of the product.

Product Description
3.1. Product Description
The Viper-12A series consists of managed 12 port routing switches optimized
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-12A series 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 the 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 the 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 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-12A series is very well suited for deployment in any
other application with severe operating conditions and tough environments, for
instance in the mining industry.
3.2. Available Models
