How to reset the factory settings /
What if I forget my password
If you have forgotten the NETA-21 password, do as follows:
1. Name any .n21 full system backup image as a restore.n21 image or use a restore.n21
image provided by ABB.
Full system restore.n21 files are available from ABB Download Center.
2. Put the file in the SD memory card root folder.
3. Boot the NETA-21 up with the SD memory card inserted.
A full system restoration also makes a full system backup of the previous system
installation (which can be used to analyze the system afterwards).
A faster way to reset all settings to default values is to trigger a direct factory reset. This
option removes all data permanently. Do as follows:
1. When you have switched off the NETA-21 after a software update, connect a straight-
through Ethernet (Cat5 or higher) cable between the PNL1 and PNL2 ports.
Note: Crossover Ethernet cables cannot be used.
2. Switch on the NETA-21 and wait for 20...30 seconds.
3. When the PNL1 and PNL2 LEDs have turned yellow, remove the cable between the
PNL ports immediately (within a minute).
4. When you have removed the cable, the NETA-21 resets to factory defaults and
reboots.
The reset function is complete within 10...20 seconds and indicated by all LEDs
(except PWR) going off and then going on again.
5. Switch off the NETA-21.
You can switch off the NETA-21 either right after it has rebooted, or wait until the STAT
LED has become green again (factory settings have been re-initialized when the STAT
LED has turned green).

How to replace the SD memory card safely

There are two buttons on the front panel of the NETA-21:
•
SD RJ45 (eject) button for ejecting the SD memory card and discovering devices
•
"Reset" button (no name indicated beside the button)
To eject th SD memory card safely, press the SD RJ45 button for a minimum of 1 second
but no longer than 2 seconds. The SD LED turns from green to blinking red/green. When
the LED has stopped blinking and there is a constant yellow light, you can remove the SD
card. If you did not eject the SD card after trying for 1 minute or if a process blocked the
access to safely remove the memory card, the SD LED turns green.

How to configure the logging of drive data to the SD card

To configure the logging of specific drive parameters manually, see the description of the
Logging sub-panel in section
By default all logged parameters and all occurred events are stored to events.db and
values.db files on the SD memory card. You can adjust the storage interval and switch to
the .csv / .log file storage, see section
