Viper-112A

The Viper-112A is a managed 12-port switch optimised for the needs of the railway rolling stock market.

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.

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.

The products are designed to last at least 20 years, at which point there is usually a mid-life upgrade. The technical lifetime used is often 300 000-500 000 hours. For this type of product the term service life is used, meaning in this context the time that the same product or similar product is available on the market. Westermo has made MTBF (mean time between failure) calculation that shows 34 years between failure. The calculation is based on hours used, temperature of environment, component lifetime etc. 500 000 hours corresponds to well over 20 years, therefore Westermo feel comfortable using 20 years as a service life for the product.
