Safety Warning Do not look directly into fibre optical fibre port or any connected fibre 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.
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-configure a network in the event of any link or hardware failure.

Figure 4. In/Out Directions Description 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.
I/O Connection The Status output is a potential free, opto-isolated normally closed solid-state relay. This can be configured 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.

3BSE034463-600 en Guide Configuration Guide Cable Factory Reset on NE820 It is possible to set the unit to factory default settings by using two straight standard Ethernet RJ-45 cables. 1. Power off the switch and disconnect all Ethernet cables (copper and fibre).
Section 3 Interface Modules Skip the Factory Reset To skip the factory reset process, just wait for approximately 30 seconds (after the ON LED starts flashing RED) without unplugging the Ethernet cables. The switch will conduct a normal boot with the existing settings. Do not power off the unit while the factory reset process is in progress.
