1.4 Security recommendations
According to the IEC 61131-2 standard and therefore in accordance with the EU directive
2006/95/EC (Low Voltage Directive), the devices are "open equipment" and in accordance
with UL/CSA certification, they are an "open type".
To fulfill requirements for safe operation with regard to mechanical stability, flame
retardation, stability, and shock-hazard protection, the following alternative types of
installation are specified:
● Installation in a suitable cabinet.
● Installation in a suitable enclosure.
● Installation in a suitably equipped, enclosed control room.
To prevent unauthorized access, note the following security recommendations.
● You should make regular checks to make sure that the device meets these
recommendations and/or other security guidelines.
● Evaluate your plant as a whole in terms of security. Use a cell protection concept with
suitable products.
● When confidential zones are used, the internal and external network are disconnected, an
attacker cannot access the data from the outside.
● Operate the device only within a protected network area.
● Use VPN to encrypt and authenticate communication from and to the devices.
● For data transmission via a non-secure network use an encrypted VPN tunnel (IPsec).
● For operation of the device in a non-secure infrastructure no product liability will be
accepted.
● Separate connections correctly (WBM. Telnet, SSH etc.).
● Limit physical access to the device to qualified personnel.
The memory card or the C-PLUG contains sensitive data such as certificates, keys etc.
that can be read out and modified.
● Lock unused physical ports on the device. Unused ports can be used to gain forbidden
access to the plant.
● Keep the software up to date. Check regularly for security updates of the product.
You will find information on this on the Internet pages "Industrial Security"
● Inform yourself regularly about security advisories and bulletins published by Siemens
productCERT.

● Restrict access to the device with a firewall or rules in an access control list (ACL -
Access Control List).
● Restrict access to the management of the device with rules in an access control list
(ACL).
● The option of VLAN structuring provides good protection against DoS attacks and
unauthorized access. Check whether this is practical or useful in your environment.
● Enable logging functions. Use the central logging function to log changes and access
attempts centrally. Check the logging information regularly.
● Configure a Syslog server to forward all logs to a central location.
● Define rules for the use of devices and assignment of passwords.
● Regularly update passwords and keys to increase security.
● Change all default passwords for users before you operate the device.
● Only use passwords with a high password strength. Avoid weak passwords for example
● Make sure that all passwords are protected and inaccessible to unauthorized personnel.
● Do not use the same password for different users and systems or after it has expired.
This section deals with the security keys and certificates you require to set up SSL.
● We strongly recommend that you create your own SSL certificates and make them

1.4 Security recommendations
● Handle user-defined private keys with great caution if you use user-defined SSH or SSL
keys.
● Verify certificates and fingerprints on the server and client to avoid "man in the middle"
attacks.
● We recommend that you use certificates with a key length of 2048 bits.
● Change keys and certificates immediately, if there is a suspicion of compromise.
● Avoid or disable non-secure protocols, for example Telnet and TFTP. For historical
reasons, these protocols are still available, however not intended for secure applications.
Use non-secure protocols on the device with caution.
● Avoid or disable non-secure protocols. Check whether use of the following protocols is
necessary:
– PNIO
– Broadcast pings
– Non authenticated and unencrypted interfaces
– ICMP (redirect)
– MRP, HRP
– GMRP and IGMP
– LLDP
– Syslog
– RADIUS
– DHCP Options 66/67
– TFTP
– GMRP and GVRP
– Multicast routing
● The following protocols provide secure alternatives:
– SNMPv1/v2 → SNMPv3
Check whether use of SNMPv1 is necessary. SNMPv1 is classified as non-secure.
Use the option of preventing write access. The product provides you with suitable
setting options.
If SNMP is enabled, change the community names. If no unrestricted access is
necessary, restrict access with SNMP.
Ethernet switches forward data packets directly from the input port to the appropriate output
port during data exchange based on the address information. Ethernet switches operate on a
direct delivery basis.
Essentially, switches have the following functions:
● Connecting collision domains / subnets
Since repeaters and star couplers (hubs) operate at the physical level, their use is
restricted to the span of a collision domain. Switches connect collision domains. Their use
is therefore not restricted to the maximum span of a repeater network. On the contrary,
extremely large networks with very large spans are possible with switches. The distances
achieved depend on the fiber-optic interfaces used in the devices and the FO fibers used
(see technical specifications).
● Load containment
By filtering the data traffic based on the Ethernet (MAC) addresses, local data traffic
remains local. In contrast to repeaters or hubs, which distribute data unfiltered to all ports
/ network nodes, switches operate selectively. Only data intended for nodes in other
subnets is switched from the input port to the appropriate output port of the switch. To
make this possible, a table assigning Ethernet (MAC) addresses to output ports is
created by the switch in a "teach-in" mode.
● Limiting the propagation of errors to the subnet involved.
By checking the validity of a data packet on the basis of the checksum which each data
packet contains, the switch ensures that bad data packets are not transported further.
Collisions in one network segment are not passed on to other segments.
With over 95% of LANs based on Ethernet, this is the most commonly used technology. The
use of switches is particularly important: They allow extensive networks with large numbers
of nodes to be set up, increase the data throughput, and simplify network expansion.
The IE Switches X-300 from SIMATIC NET are designed for use in high-speed plant
networks that will also meet future requirements. With the HRP redundancy function and
standby linking of rings, high network availability can be achieved. HRP and standby link
reconfigures the network within 300 ms. Support of IT standards such as VLAN, RSTP,
IGMP, and GARP makes seamless integration of automation networks in existing office
networks possible.
The IE Switches X-300 are designed for use in switching cubicles and cabinets.
The IE Switches X-300 simplify the expansion of a network regardless of the network
topology.
You can use an IE Switch X-300 in the following network topologies:
● Linear structure
● Star/tree structure
● Ring with redundancy manager
The maximum cable length is 70 km for single mode gigabit transmission. A mixed topology
consisting of IE Switch X-300 devices and OSMs/ESMs is possible at the electrical ports. A
mixed topology consisting of IE Switch X-300 devices and an OSM via the optical ports is not
possible.
Using an IE Switch X-300 as the redundancy manager in a ring with redundancy manager
provides greater availability. If there is an interruption on the connection between these
switches, the IE Switch X-300 used as redundancy manager acts like a switch and in a very
short time creates a line from the ring. As a result, a functional, end-to-end structure is
restored. For information on this topic, refer to the Configuration Manual "SIMATIC NET Industrial Ethernet Switches SCALANCE X-300 SCALANCE X-400."

3.3 Ring with redundancy manager
The redundancy manager function is enabled by the SELECT/SET button or by a setting in
the software. For more detailed information, refer to the configuration manual
"SCALANCE X-300 and SCALANCE X-400 Industrial Ethernet Switches".
In contrast to the ring ports of the redundancy clients, the ring ports of the redundancy
manager are disconnected when the network is operating problem-free. The IE Switch X-300
operating in the role of redundancy manager mode monitors the connected bus over its ring
ports and switches the ring ports through if there is an interruption on the connected bus; in
other words, it restores a functioning bus over this substitute path. Reconfiguration is
achieved within 0.3 s. As soon as the problem is eliminated, the original topology is restored;
in other words, the ring ports in the redundancy manager are disconnected from each other
again.
In a ring with media redundancy, only one device can operate as the redundancy manager.
An electrical ring with redundancy manager can be set up via the RJ-45 connectors that
allow attachment of electrical (twisted pair) connections (10, 100 and/or 1000 Mbps). The
SCALANCE X310FE is an exception to this. This device only allows attachment of electrical
(twisted-pair) connections at 10 or 100 Mbps.
The use of the IE Switch X-300 in an optical ring (1000 Mbps, with SCALANCE X-300EEC
100Mbps) with a redundancy manager is also possible with the exception of the devices
SCALANCE X310 and SCALANCE X310FE.
You can configure which ports take on the function of ring ports individually. The following
table shows the factory defaults for the ring ports.
The example of redundant coupling of two network segments as shown here, for example
rings with a redundancy manager, can be implemented homogeneously with all SCALANCE
X300 variants.
Image 3-5 Redundant coupling of two subnets in mixed operation with SCALANCE X310 and
SCALANCE X308-2
In this case, network segments are rings with a redundancy manager (RM). The rings can
also be interrupted at one point (linear topology).
For a redundant link as shown in the figure, two IE Switches X-300 must be configured within
a network segment. This configuration is set in Web Based Management, Command Line
Interface or using SNMP access. For more detailed information, refer to the "Configuration
Manual SCALANCE X-300 and SCALANCE X-400 Industrial Ethernet Switches". The two
IE Switches X-300 connected in the configuration exchange data frames with each other to

synchronize their operating statuses (one device is master and the other slave). If there are
no problems, only the link from the master to the other network segment is active. If this link
fails (for example due to a link-down or a device failure), the slave activates its link as long
as the problem persists. Reconfiguration takes place within 0.3 s.
Switches X-300 or SCALANCE X408-2 devices are used exclusively for redundant
rings, the coupling links can also be designed with a gigabit

Data transmission at 10 Mbps and at 100 Mbps is over two wire pairs (pin 1, 2, 3, 6) of the
twisted pair cable. For 10 Mbps, at least a category 3 (Cat 3) and for 100 Mbps, at least a
four-wire (2 x 2) category 5 (Cat 5) cable is necessary.
The maximum transmission range (segment length) is 100 m.
A node or network segment is connected to an 8-pin RJ-45 jack with securing collar. Due to
its flush fitting with an IE FC RJ-45 Plug 180 / IE FC RJ45 Plug 145 connector, the securing
collar ensures a robust connection suitable for industry that provides tensile and bending
strain relief for the inserted connector.

4.3 Interfaces and signaling contact of the switches
PoE-compliant devices can be divided into the following groups:
● PSE - power sourcing equipment
These inject power onto the Ethernet cable.
● PD - powered devices
These are supplied with power via Ethernet.
As a PSE, the X308-2M PoE supplies PoE-compliant devices with power over Ethernet. The
48 V power required to supply the powered devices is generated internally on the switch, no
extra power supply unit is necessary.
The X308-2M PoE uses the "alternative A" for this. Per RJ-45 port, a maximum of 15.4 W
are available for supplying a PoE-compliant device. If a Cat5/Cat5e cable with a maximum
length of 100 m is used, the connected device can be supplied with a power of 12.95 W.
The PoE ports meet the conditions listed in the IEEE 802.3af / IEEE 802.3at standard
(type 1) for environment A , in other words power supply over Ethernet within a power supply
system. For details of configuring and enabling PoE for individual ports, refer to the
configuration manual SCALANCE X-300 / X-400 on the accompanying CD.

All ports meet the requirement of 1.5 kV isolation voltage to the shield and between the ports
(corresponds to IEEE802.3, Environment B).
Port group 1: P1, P2, P3 and P4
The transmission rate of the optical gigabit ports is 1 Gbps.
4.3 Interfaces and signaling contact of the switches
Transmission with 1000Base-SX is defined in the IEEE 802.3z standard and is specified as
1000 Mbps transmission rate and full duplex.
Data is transmitted over multimode FOC. The wavelength is 850 nm.
The core diameter of the multimode FOC is 50 µm; the light source is an LED. Many modes
(light beams) are used for signal transmission. The propagation times of the light pulses
(dispersion) restrict the maximum range considerably.
The maximum transmission range (segment length) is 750 m when using SIMATIC NET
fiber-optic multimode FOC with SC duplex connectors.
SC duplex female connectors are used.
On the IE Switches X-300EEC, devices are connected via LC jacks.
The transmission rate of the optical gigabit ports is 1 Gbps.
Transmission with 1000Base-LX is defined in the IEEE 802.3z standard and is specified as
1000 Mbps transmission rate and full duplex.
Data is transmitted over single mode FOC. The wavelength is 1310 nm or 1550 nm.
The core diameter of the single mode FO cable is 9 or 10 µm; the light source is a laser
diode. To transmit a signal, only one mode (light beam) is used greatly reducing dispersion.
As a result, the maximum range of single mode FOC is greater than that of multimode FOC.
The maximum transmission distance (segment length) is 120 km for 1000Base-LX
transmission.

SC duplex female connectors are used.
FC duplex female connectors with the following characteristics are used:
● Maximum range: up to 3 km
● Wavelength: 1310 nm
● Transmission mode: Multimode
● Standard: 100Base-FX
The signaling contact (relay contact) is a floating switch with which error/fault states can be
signaled by breaking the contact.
● The signaling by the signaling contact is synchronized with the fault LED, in other words,
all errors displayed by this LED (freely configurable) are also signaled on the signaling
contact.
● If an internal fault occurs, the fault LED lights up and the signaling contact opens.
● The connection or disconnection of a communication node on an unmonitored port does
not lead to an error message.
● The signaling contact remains activated until the error/fault is eliminated or until the
current status is entered in the fault mask as the new desired status.
DO NOT REMOVE C-PLUG WHILE POWER IS ON
The C-PLUG may only be removed or inserted when the power supply to the device is
turned off.
In a device with a varnished printed circuit board, you may only use a C-PLUG with a
varnished board.
The C-PLUG is an exchangeable medium for storage of the configuration data of the IE
Switch and ships with the product. This means that the configuration data remains available
if the IE Switch is replaced.
Power is supplied by the IE Switch. The C-PLUG retains all data permanently when the
power is turned off.
If an empty C-PLUG (factory settings or deleted with the Clean function) is inserted, all the
configuration data of the IE Switch is saved to it automatically when the device starts up.
Changes to the configuration during operation without operator intervention are saved on the
C-PLUG if this is in the "ACCEPTED" status.
An IE Switch with an accepted C-PLUG inserted uses the configuration data of the C-PLUG
automatically when it starts up. Acceptance is possible only when the data was written by a
compatible device type.
This allows an IE Switch to be replaced quickly and simply. The C-PLUG is taken from the
failed component and inserted in the replacement. The first time it is started up, the
replacement device has the same configuration as the failed device except for the MAC
address set by the vendor.
Inserting a C-PLUG that does not contain the configuration of a compatible device type,
accidentally removing the C-PLUG or general malfunctions of the C-PLUG are signaled by
the diagnostics mechanisms of the IE Switch (LEDs, WEB-based management, SNMP, CLI
and PROFINET diagnostics).
