1.2 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.

You will recognize the PoE-capable ports from the printed PoE logo.
The voltage is supplied through the wire pairs transmitting the signal
(phantom voltage). The individual ports are not electrically insulated from
each other.
The following conditions are met in accordance with IEEE 802.3af:
Endpoint PSE
Alternative A
The OCTOPUS ...PoE... and OS32... devices meet the requirements of
EN 50155:
Railway applications – electronic systems in railway vehicles.
1.3 Power supply
The supply voltage and the signal contact are connected by means of a 5-pin
M12 connector.
You find the prescribed tightening torque in General technical data section
on page 34.
The supply voltage can be connected redundantly. Both inputs are
uncoupled. There is no distributed load. With redundant supply, the power
supply unit with the higher output voltage supplies the device on its own. The
supply voltage is electrically isolated from the housing.
With non-redundant supply of the mains voltage, the device reports a power
failure. You can avoid this message by changing the configuration in the
management, or, with power supply units of the same type, by feeding the
supply voltage in through both inputs.
For more detail see
“Wiring the connectors for supply voltage and signal contact” on page 26.

1.4 PoE voltage (optional)
The PoE voltage for the OCTOPUS ...PoE... and OS32... devices is
connected via a 5-pin M12 connector (“A”-coded, e.g. ELWIKA 5012 PG7
from Hirschmann, supplied).
You find the prescribed tightening torque in General technical data section
on page 34.
The OCTOPUS ... PoE... and OS32... devices are supplied with PoE voltage
(48 V DC safety low voltage) via an external power supply unit. The PoE
voltage is fed into the 5-pin M12 connector of the OCTOPUS ... PoE... or
OS32... The PoE voltage to the twisted-pair cables is supplied via the wire
pairs transmitting the signal (phantom voltage).
For more detail see
“Connecting the PoE voltage (optional)” on page 27.
1.5 Ethernet ports
You can connect end devices and other segments to the device ports using
twisted pair cables or optical fibers (F/O).
You find information on pin assignments for making patch cables here:
“Pin assignments” on page 18.
1.5.1 10/100 Mbit/s twisted pair port

1.6 Display elements
After the supply voltage is set up, the software starts and initializes itself.
Afterwards, the device performs a self-test. During this process, various
LEDs light up. The process takes around 60 seconds.
Figure 1: Display elements
1 - Port status LEDs (here: for ports 1 to 4)
2 - Device status LEDs
1.6.1 Device state
These LEDs provide information about conditions which affect the operation
of the whole device.
If the manual adjustment is active on the “FAULT” signal contact, then the
detected error display is independent of the setting of the signal contact.
LED Display Color Activity Meaning
P1 Supply voltage 1 Green Lights up Supply voltage is on
None Supply voltage is too low
P2 Supply voltage 2 Green Lights up Supply voltage is on
None Supply voltage is too low
FAULT Signal contact Red None The signal contact is closed - it is not
reporting any detected errors.
Lights up The signal contact is open - it is reporting
a detected error.
RM Ring Manager — None The RM function is deactivated.
Green Lights up The RM function is active.
The redundant port is disabled.
flashing The device detects an incorrect
configuration of the HIPER-Ring (e.g. the
ring is not connected to the ring port).
Yellow Lights up The RM function is active.
The redundant port is enabled.

1.6.2 Port Status
These LEDs display port-related information. During the boot phase, they
indicate the status of the boot process.
Note: You can query the port status for activated Power over Ethernet via the
software management.
1.7 Management interfaces
1.7.1 V.24 interface (external management)
At the V.24 connection, a serial interface is provided for the local connection
of an external management station (VT100 terminal or PC with
corresponding terminal emulation). This enables you to set up a connection
to the Command Line Interface (CLI) and to the system monitor.
The socket housing is electrically connected to the housing of the device.
For devices with PoE the V.24 interface uses the housing potential, and for
devices without PoE it uses the supply voltage potential.
