Description of the device variants
1.2.1
Devices without Power over Ethernet
The following device variants provide 8 to 24 10BASE-T/100BASE-TX ports
(RJ45 connections) for connecting network segments or terminal devices:
OCTOPUS 8M, OCTOPUS 8M-Train, OCTOPUS 8M-Train-BP
OCTOPUS 16M, OCTOPUS 16M-Train, OCTOPUS 16M-Train-BP
OCTOPUS 24M, OCTOPUS 24M-Train, OCTOPUS 24M-Train-BP
The following device variants also feature a bypass function on two ports for
bridging periods without power:
OCTOPUS 8M-Train-BP
OCTOPUS 16M-Train-BP
OCTOPUS 24M-Train-BP
As long as the device is switched off and during the system start, relays
connect port 4 and port 8 to each other on a crossed basis. This passive
bypass enables data communication between the devices connected to
these ports.
As soon as the device is ready to operate, it automatically deactivates the
bypass function and actively exchanges data.
The OCTOPUS devices … Train and Train-BP correspond to the
requirements as per EN 50155:
Rail applications – electronic systems in railway vehicles.
