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).
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 ca-
ble).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 flashing red.
The ON LED flashing indicates that the unit is now ready to be reset to factory de
-
fault. 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 flashing. 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.
