Safety
Warning
Do not look directly into bre optical bre port or any connected bre although
this unit is designed to meet the Class 1 Laser regulations.
When this unit is operated at an ambient temperature above 60°C, the External
Surface of Equipment may exceed Touch Temperature Limit according to EN/
IEC/UL 60950-1. To reduce the risk of re, use on No. 26 AWG or larger (e.g.,
24 AWG) UL listed or CSA certied telecommunication line cord.

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-congure 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, trafc 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.

Power and CPU Module
Regardless of NE820 model, all units will be delivered with the power and CPU
interface in the slot on the far left. The power and CPU module holds a power
board and a CPU board. The isolated power supply has redundant power inputs and
allows for a wide operating voltage range (refer to Interface Modules). The digital
IO-port can be used for monitoring the unit. For more information, see ABB NEOS
Management guide.
The CPU module holds several interfaces. Three RJ-45 connectors with support for
Ethernet 1000BaseTX, a USB port for easy save/load of system conguration and a
console port. The console connector is a micro USB cable that connects to a FTDI
FT232R USB to serial converter internally. For drivers, please go to www.ftdichip.
com and download the appropriate VCP driver. For detailed information on LED
indicators, see section on LED indicators Power/CPU.

To minimise the risk of interference, a shield-
ed cable is recommended when the cable
is located inside 3 m boundary to the rails
and connected to this port. The cable shield
should be properly connected (360°) to an
earthing point within 1 m from this port.
This earthing point should have a low imped-
ance connection to the conductive enclosure
of the apparatus cabinet, or similar, where
the unit is built-in. This conductive enclosure
should be connected to the earthing system
of an installation and may be directly connect-
ed to the protective earth.

Power Connection
NE820 supports redundant power connection. The positive inputs are +DC1 and
+DC2, the negative input for both supplies are –COM. Connect the primary volt-
age (e.g. +24 VDC) to the +DC1 pin and return to one of the –COM pins on the
power input.

The Status output is a potential free, opto-isolated normally closed solid-state relay.
This can be congured to monitor various alarm events within the NE820 unit, see
ABB NEOs Management Guide. An external load in series with an external voltage
source is required for proper functionality. For voltage/current ratings, see Interface
specications section.
