Overview
The SCALANCE X-300PoE product line comprises compact
Industrial Ethernet switches for constructing electrical and/or
optical line, star and ring topologies operating at data transfer
rates of 10/100/1 000 Mbit/s.
•
Partially modular version with four integrated electrical,
PoE-enabled Ethernet ports and two slots for 2-port media
modules
•
High-speed media redundancy through integral redundancy
manager both for Gigabit Ethernet (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
standards: Establishment of virtual networks (VLANs)
•
Redundant integration into higher-level networks thanks to
support for standardized redundancy procedures (Rapid
Spanning Tree Protocol)
•
PROFINET diagnostics, SNMP access, integrated web server
and automatic e-mail transmission function for remote
diagnostics and signaling via the network
Product version
Full Gigabit switches
SCALANCE X308-2M PoE
(Power over Ethernet)
•
For the construction of electrical and/or optical line, ring and
star topologies with
- four integrated electrical, PoE-compatible Gigabit Ethernet
Ports and two slots for any 2-port media modules (see
"Media modules for SCALANCE X-300")
•
Star coupler in the plant bus (redundant connection is
possible)
■
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 fiber-optic or
twisted pair cables (redundancy manager, standby function,
and RSTP are 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 failure and higher availability of the
plant networking due to latching of the RJ45 FastConnect
connectors in the sleeve of the RJ45 ports
•
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 the use of configuration and
diagnostics integrated in STEP 7
