How to update the NETA-21 firmware
The following sections show how to update the NETA-21 firmware with an SD memory
card. The NEXA-21 does not require any firmware updates.
In brief:
•
With firmware 2.02 or any of the later releases:
Put the update file on the root of the SD card, and the NETA-21 applies the update (or
full system restore.n21) on the next reboot. The update takes about 5 minutes. LEDs
STAT and SD are blinking during the update.
•
With firmware 2.01 and earlier releases:
Only the .NTU update mechanism over the web UI is supported. See section
the NETA-21 firmware over a remote web connection
on page
For instructions on how to update several NETA-21 units at the same time locally with an
SD card, see section
Updating the NETA-21 firmware locally with SD card(s)
on page
Notes:
•
From firmware version 2.00 onwards, you can update all delivered NETA-21 units.
•
The firmware update keeps all previous settings of the NETA-21. This means that a
remotely connected NETA-21 stays reachable after the firmware update.
•
Do a factory reset after major firmware updates, especially when you upgrade the
NETA-21 firmware from version 2.11 or older releases, or when you upgrade the
NETA-21 firmware more than one minor version number The factory reset restores the
network settings.
