OCTOPUS 8M/16M/24M/OS32
Release 10 05/2012 17
2 Assembly and start-up
The devices have been developed for practical application in a harsh
industrial environment.
On delivery, the device is ready for operation.
The following procedure has been proven to be successful for the assembly
of the device:
Unpacking and checking
Connecting the plug for the supply voltage and the signal contact
Installing the device and grounding
Connecting the supply voltage, starting up
Connecting the data lines
2.1 Installing the device
2.1.1 Unpacking and checking
Check that the contents of the package are complete (see page 39
“Scope of delivery”).
Check the individual parts for transport damage.
2.1.2 Installing the SFP modules (optional)
Note: Only use SFP modules that are permitted for OS32 devices (see on
page 40 “Accessories”).
You can combine these modules with each other in any way, or you can
leave SFP slots unused.
Before attaching an SFP module, first remove the protective cap over the
socket.
Push the SFP module with the lock closed into the socket until it latches
audibly in place.
(see fig. 2)
Note: The SFP mounting tool available as an accessory (see fig. 8) makes it
easier for you to insert modules.

2.1.3 Connecting the connector for
supply voltage and signal contact
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).
Note: The permitted cable diameter for connector ELWIKA 5012 PG7 is
4 mm to 6 mm. To ensure the watertightness of the OCTOPUS 8M/16M/
24M/OS32 device, only use voltage supply cables with a diameter within the
specified range.
Connecting the supply voltage
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 main voltage, the device reports a loss
of power. You can avert this message by supplying the voltage over the
two inputs or changing the configuration in the management.

Release 10 05/2012 19
Connecting the 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).
Make sure that the external power supply unit you use to provide the
PoE voltage fulfills the following basic prerequisites:
Insulation requirements according to IEEE 802.3af (insulation
resistance 48 V, output to “rest of the world” 2,250 V DC for 1 min.).
Output power < 150 W
Current limitation < 5 A
Power supply unit and PoE media module form a “limited power
source” according to IEC 60950-1.
The external PoE power supply unit must be able to provide the
power for the connected PDs.
10 ms failure bridging (incl. Powered Devices) in accordance with
EN 61131-2
CE marking in accordance with 2004/108/EG
Meets requirements of EN 50155 – electronic systems in railway
vehicles
Connect the PoE voltage to the 5-pin M12 connector included in the
scope of delivery as shown in the following diagram.
Make sure the following requirements are met:
Supply line length < 3 m
Cross section of the supply lines ≥0.75 mm2or AWG 18.
Note: Do not operate the OCTOPUS ... PoE... and OS32... devices in
series. Only connect single external power supply units directly to an
OCTOPUS... PoE... or OS32... device.

“FAULT” signal contact
The signal contact (“FAULT”, for pin assignment see table 2) is used
for the remote monitoring of the device to enable remote diagnostics.
You can specify the type of function monitoring in the Management.
You can also use the Management to set the signal contact manually
and thus control external devices.
A break in contact is used to report the following conditions via the
potential-free signal contact (relay contact, closed circuit):
The failure of at least one supply voltage.
The device is not operational.
The loss of connection at at least one port. The report of the link status
can be masked by the Management for each port. In the delivery state,
link status monitoring is deactivated.
The loss of ring redundancy reserve.
A detected error during the self-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.
Connecting the supply voltage and signal lines.
2.1.4 Installing the device and grounding
Installing the device
To protect the exposed contacts of the components still to be installed
from dirt, connect the individual system components in a dry and clean
working area. Seal unused ports with the protection caps available as
accessories.
Note: Connectors are not electrical isolating devices. Therefore, first plug
the connector into the power supply plug and then switch on the power
supply.
