Overview
The SCALANCE XR-300PoE Industrial Ethernet switches are
partly modular, high-performance, industry-standard switches
for the construction of electrical and/or optical line, ring and
star topologies at data transfer rates of 10/100/1 000 Mbit/s,
designed for installation in 19" control cabinets
•
As many as 24 electrical and/or optical interfaces
(10/100/1 000 Mbit/s), of which 16 are integrated RJ45 ports,
eight of which are PoE-compatible;
up to four electrical and/or optical 2-port media modules can
additionally be inserted in the media module slots of the basic
unit
•
High-speed media redundancy through integral redundancy
manager both for Gigabit Ethernet (with SCALANCE X-300,
X-400) and Fast Ethernet (e.g. in combination with
SCALANCE X-200 switches)
•
Seamless integration of automation networks into existing
corporate networks thanks to support for a host of IT standard
functions (VLANs, IGMP-Snooping/Querier, STP/RSTP, Link
Aggregation, Quality of Service)
•
Redundant integration into higher-level networks thanks to
support for standardized redundancy procedures (Spanning
Tree Protocol/Rapid Reconfiguration Spanning Tree Protocol/
MRP)
•
Remote diagnostics by means of PROFINET diagnostics, Web
browser, CLI, or SNMP
■
Benefits
•
Unlimited flexibility during network expansions (e.g. more
terminals) or conversion (e.g. switching from copper to fiber-
optic cable) and reduction of the storage costs due to the
modular construction using port modules
•
Saving of additional power supply units and cabling for
terminals by means of PoE voltage supply
•
High availability of the network due to
- redundant voltage feed
- redundant network structures based on FOC or Twisted Pair
(redundancy manager, standby function and STP/RSTP
integrated)
-
easy device replacement by means of plug-in C-PLUG swap
medium
- very fast reconfiguration of the network in event of a fault
•
lower susceptibility to faults and higher availability of the plant
networking by latching the RJ45 FastConnect plug in the
retaining collar of the RJ45 port modules
•
Protection of investment through integration into existing
network management systems by means of standardized
SNMP access
•
Time saving during engineering, commissioning and in the
operating phase of a plant due to integrated configuration and
diagnostics in STEP 7, without additional software
•
Space savings in control cabinet due to flexible cable outlet
on the front or rear of the device

Application
The SCALANCE XR-300PoE is ideal for use in plant networks
and for integrating the industrial network into an existing corpo-
rate network. Both at the field level and the control level, the
switch performs the network with the distributed field devices
and ensures high plant availability with extensive diagnostics
options and high transmission speeds. The modularity permits
perfect adaptation to the respective application through the use
of electrical and also optical media modules.
The SCALANCE XR-300PoE supplies PoE-compatible devices,
such as IWLAN access points SCALANCE W, IP cameras and IP
telephones, with energy over the data cable and is suitable for
constructing electrical and/or optical Industrial Ethernet linear,
star or ring structures with up to 24 ports, of which 16 RJ45 ports
are pre-assigned. Eight of these support PoE. The switch can
be optionally equipped with four electrical and/or optical 2-port
media modules. It can also be used as a hub in the plant bus
(redundant connection is possible).
The SCALANCE XR324-4M PoE TS (

is suitable for use in railway applications due to its EN 50155
specification. Media modules that have been approved for train
applications must be used.
