Features and Fields of Application of the FL SWITCH MM HS
– Increased network performance by filtering data traffic:
- Local data traffic remains local.
- The data volume in the network segments is reduced.
– Easy network expansion and network configuration.
– Coupling segments with different transmission speeds.
Automatic detection of 10 Mbps or 100 Mbps data transmission rate with auto
crossing.
– Increased availability through the use of redundant transmission paths with Rapid
Spanning Tree. Support of various topologies and meshed structures as well as ring
topologies with special ring detection. Fast switch-over times with RSTP fast ring
detection.
– Configuration of switches using web-based management, SNMP, Telnet or locally via
a V.24 (RS-232) interface.
– Multicast filtering (static and dynamic).
– IGMP snooping, optional querier function.
– VLAN support according to 802.1Q (32 VLANs).
– Port security functions.
– Access control for web-based management (WBM).
– Integration in PROFINET environments.
– Topology detection using LLDP (Link Layer Discovery Protocol).
– Address assignment via BootP, DHCP, DCP or statically.
– Address assignment using DHCP option 82 relay agent.
– Support of Power over Ethernet (PoE).
1.1.1 System Components
Central element
FL SWITCH MM HS
The head station is the central element of the Modular Managed Switch System. It contains
all the management functions, and the interface modules provide it with the desired
interfaces to the network. Up to two extension modules can be connected to a head station,
which means that the maximum system configuration comprises 24 Ethernet ports.
FL SWITCH MM HS/M Thanks to certification according to Germanischer Lloyd (GL Certificate No. 2427504 HH),
the FL SWITCH MM HS/M head station, the FL MXT/M extension module, and some of the
available interface modules have been approved for shipbuilding and off/onshore
applications. Please observe the list of GL-certified components on page 11-8. Please also
observe the notes for supply voltage connection on page 2-10.
Always switch off the supply voltage before inserting or removing extension modules
(FL MXT).
Do not connect more than two extension modules (FL MXT) to one head station.
