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.

via 10BASE-T/100BASE-TX. With PoE, these terminal devices are powered
by the twisted-pair cable.
Depending on the device variant, the OCTOPUS ...PoE... and OS32
provides six to eight 10BASE-T/100BASE-TX ports (M12 sockets) for
connecting network segments or PoE terminal devices (PD, Powered
Device) for all IEEE802.3af classes up to a maximum power output of
15.4 W.

The current is supplied on wire pairs transmitting the signal; 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 (A coding, e.g.
ELWIKA 5012 PG7 from Hirschmann, included in the delivery).
Redundant power supplies can be used. Both inputs are uncoupled. There is
no distributed load. With redundant supply, the power supply unit supplies
the device only with the higher output voltage. 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 via both inputs.
You will find more information on page 23.
1.4 PoE supply voltage (optional)
The PoE supply voltage for the OCTOPUS ...PoE... and OS32... devices is
connected via a 5-pin M12 connector (A coding, e.g. ELWIKA 5012 PG7 from
Hirschmann, supplied).
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).
You will find more information on page 25.

1.5.5 “FAULT” signal contact
The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:
The failure of at least one supply voltage.
The device is not operational.
The failure of the connection on at least one port.
The report of the link status can be masked by the Management for each
port. In the delivery state, is deactivated.
Failure of the ring redundancy reserve.
Errors detected during the self-diagnostic test.
Incorrect configuration of the HIPER-Ring or ring coupling.
The following condition is also reported in RM mode:
Ring redundancy reserve is available. On delivery, there is no ring
redundancy monitoring.
You can also use the Management to set the signal contact manually and
thus control external devices.
1.5.6 ACA interface (ACA21-M12)
The ACA socket has an interface for the local connection of an
AutoConfiguration Adapter ACA 21-M12. It is used for saving/loading the
configuration and diagnostic functions, and for loading the software.
The ACA interface is a shielded 5-pin M12 socket with A coding.
Note: The AutoConfiguration adapter available for certain Hirschmann
devices ACA11-M12 is not designed to be used with OCTOPUS
8M/16M/24M/OS32 devices.

1.5.7 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.
Figure 1: Terminal cable for connecting an external Management Station
You will find a description of the V.24 interface in the “Basic Configuration
User Manual” on the CD-ROM.
Note: You will find the order number for the terminal cable, which is supplied
separately, in the Technical Data chapter (see page 42).

1.6 Display elements
After the operating 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 2: Display elements
1 - Port status LEDs (here: for ports 1 to 4)
2 - Device status LEDs
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 The supply voltage is on.
None The supply voltage is too low.
P2 Supply voltage 2 Green Lights up The supply voltage is on.
None The supply voltage is too low.
FAULT Signal contact Red None Signal contact is closed, it is not reporting
a detected error.
Lights up The signal contact is open, it is reporting
an error.
RM Ring Manager — None The RM function is deactivated.
Green Lights up The RM function is active.
The redundant port is disabled.
flashing Incorrect configuration of the HIPER-Ring
(e.g. the ring is not connected to the ring
port).
