Cable Factory Reset on NE840
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 bre).
2. Connect an Ethernet cable between Ethernet port 1/1 and Ethernet port 1/2 (that
is, connect Ethernet ports 1 and 2 on in the left most slot by an Ethernet cable).
The ports need to be connected directly by an Ethernet cable, that is, not
through a hub or switch. Use a straight cable – not a cross-over cable – when
connecting the ports.
3. Power on the unit.
4. Wait for the unit to start up. Control that the ON LED is ashing red.
The ON LED ashing indicates that the unit is now ready to be reset to factory
default. You now have the choice to go ahead with the factory reset, or to skip
factory reset and boot as normal.
Proceed with Factory Reset
Acknowledge that you wish to conduct the factory reset by unplugging the Ethernet
cables. The ON LED will stop ashing. This initiates the factory reset process, and
after approximately 1 minute the unit will restart with factory default settings.
When the switch has booted up, the ON LED will show a green light, and is now
ready to use.
