Section 1 Managed Ethernet Switch
Section 1 Managed Ethernet Switch
NE820 is an Industrial switch made for harsh enviroments. The switch can be used in
either 100 Mbit or Gigabit networks due to our multi-rate SFP solution. Our unique
FRNT (Fast Recovery of Network Topology) technology is the fastest protocol on the
market to re-congure a network in the event of any link or hardware failure. That is
why NE820 is also used in safety critical applications such as tunnels, trafc signal
control and railway systems.
Installations in harsh environments and places with heavy electrical interference
require the use of a reliable media. NE820 provides a number of solutions using bre
optic transceivers. Multi- or singlemode transceivers can be used to build point-to-
point or redundant ring networks with ranges up to 120 km between each switch. Our
BIDI transceiver, which transmits and receives data on a single bre can be used in
applications where the number of bre cores are limited.
Real-time properties are implemented in the switch in order to achieve determinism
for real time critical applications. NE820 supports QoS (Quality of Service) with four
priority queues and strict priority scheduling as well as HoL (Head of Line Blocking
Prevention). All to assure that the data network is deterministic.
Housing
The back end holds a casted DIN-clip for stable mounting on a DIN-rail. Direct wall-
mount is also possible using the four brackets in each corner. The back end also holds
the earth connection. For detailed ground connection information, refer to section on
Earth Connection.
