Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Security information
1.1 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation)
are in place.

NOTICE
Electrostatic sensitive devices (ESD)
Electronic modules contain electrostatic sensitive components
These components can easily be destroyed if handled incorrectly.
Note the following instructions to avoid damage.
• Touch electronic modules only when you absolutely need to work on them.
• If electronic modules need to be touched, the body of the person involved must 󹪝rst be
electrostatically discharged and grounded.
• Do not bring electronic modules in contact with electrically isolating materials such as
plastic 󹪝lm, isolating table top pads or clothing made of synthetic 󹪝bers.
• Place the modules only on conductive surfaces.
• Pack, store and transport electronic modules and components only in conductive packaging
such as metalized plastic or metal containers, conductive foam or household aluminum foil.

Setting the fault mask
Factory setting
In its delivery condition (factory default), the following settings are monitored via the
message screen:
• Link up to all ports
• Redundant power supply (L1+/M1 und L2+/M2) connected
When you turn the device on and at least one of the settings is not ful󹪝lled, the device
registers a fault. Switch the device to the required operating mode and save these settings in
the message screen.
Changing the setting
The changed settings remain after cycling power to the device.
Di󹪜erent settings are made depending on how long you hold down the SET button, as
described in the following table:

3.6 Power over Ethernet (PoE)
Function
The "Power over Ethernet" function supplies connected devices with power via the Ethernet
cable. Devices supplied with power via an Ethernet cable do not require a separate voltage
source.
PoE-compliant devices can be divided into the following groups:
• Power source (PSE - Power Sourcing Equipment)
These inject power onto the Ethernet cable.
• Power consumer (PD - Powered Device)
These are supplied with power via the Ethernet cable.
3.6.1 Power and voltage range according to the standard
Note the values speci󹪝ed for the power of the power source, so that the power supply is ensured
at the power consumers according to the standard.

3.6.2 PoE properties of the devices
Note
Turn o󹪜 the power source before you disconnect the PoE cable of a power consumer.
Power source
• The device can supply energy consumers of the standards IEEE802.af Type 1 and IEEE802.at
Type 2.
• In total, a power source can make PoE power of 120W available (including line losses).
The power can be distributed to the ports as desired.

PoE ports
• All RJ45 ports are PoE ports.
• The PoE ports are not isolated from each other. This means that they meet the conditions
named in Environment A (IEEE 802.3): Power supply over Ethernet within a power supply
system.
• The electrical isolation of the ports against functional grounding is designed for 1500 Vrms
(1 minute). If you operate the device with plug-in transceivers, the test voltage is reduced to
500Vrms.
• The PoE ports support PoE classes 0 to 4. The ports supply connected devices with up to 30 W
per port (according to IEEE802.3af and IEEE802.3at).
3.6.3 Power transfer and pin assignment (30 W)
The table below shows the power transfer and pin assignment of the PoE ports:
Pin number Assignment
Pin 1 Positive power supply
Pin 2 Positive power supply
Pin 3 Negative power supply
Pin 4 -
Pin 5 -
Pin 6 Negative power supply
Pin 7 -
Pin 8 -
