Next generation switches improve on board rail communication network reliability
1 February, 2012
To meet the growing demand
for reliable on board railway communications networks, Westermo has introduced
a new generation of industrial Ethernet switches that provide highly robust
networks and long term field operation. Specifically designed for on board
applications around the ‘Westermo IP train concept’, the Westermo Viper series
offers a complete EN50155 Ethernet switch and routing solution that delivers an
ultra-reliable network backbone for the creation of intelligent trains.
The ‘Westermo IP Train
concept’ encompasses the Westermo Viper 212, a managed layer 3 routing switch,
The Viper 112 which offers managed layer 2 switching functionality and an
unmanaged solution, the Viper 012. These different levels allow users to select
the most appropriate level of functionality for their network whilst still
having hardware that meets the toughest environmental challenges.
With an ultra-robust design,
sealed to IP65, integrated M12 connectors and vibration resistant to military
standards, these units are ideal for situations where mechanical stress, moisture,
condensation; dirt or continuous vibrations could adversely affect the function
of standard Ethernet switches.
The WeOS operating system of
the Viper and RedFox switches is able to balance data traffic on the network to
maintain maximum throughout and stability. The introduction of increased
traffic from new cameras or video stream will therefore not affect the
stability of the entire network. In the event of any link or hardware failure
Westermo’s unique FRNT technology is able to re-configure a large network in
20ms.
For easy configuration, the Ethernet switches
can be safely accessed from anywhere in the network, or directly via a console
port on the Viper switch or an Ethernet or USB port on the RedFox switch. The
configuration can be backed up and restored in seconds using a using a special
M12 USB memory stick. An easy to use, secure web configuration interface
simplifies the setting up of a redundant ring network.
