PC ETH 1 Off PC not connected.
If an Ethernet cable is connected to the PC ETH 1 port but no one uses
the NETA-21, the LED remains blank.

• NETA-21 provides IP addresses for local devices.
Activate the DHCP server mode by pressing the SD RJ45 button for
five seconds.
• When a PC is connected and the NETA-21 has provided an IP
address for it, the LED turns steady green.
Note: The DHCP server functionality remains enabled until the NETA-21
is restarted or until the DHCP server is disabled in the web UI
(Settings –> Network interfaces –> Ethernet 1).

Blinking yellow Factory-level access/operation.
Firmware update in progress.
Note: System status (STAT LED) blinks during the firmware update.
PWR Off Power off
Green Power on
Yellow Timed power off or standby.
NETA-21 can go to the standby mode as a protective measure (eg, if the
environmental temperature is too high).
To wake up the NETA-21, press the SD RJ45 button.
STAT Green System in operation, OK
Yellow System starts up, services not yet fully operational

blinking yellow
System waits for a confirmation of the reboot operation or network
override.
• If you reboot the NETA-21 by pressing the reset button for 5 seconds
when the NETA-21 is running, the STAT LED starts blinking. Confirm
the reboot operation by pressing the SC RJ45 button. If you do not
confirm the reboot operation, it stops after a 1-minute delay.
• You can override the network settings by pressing the SD RJ45 button
for 10 seconds when the NETA-21 powers up. If you keep pressing
the button for about 20 seconds, the STAT LED starts blinking, which
indicates that you can release the button. If you do not release the SD
RJ45 button within one minute (or if the button is locked to the “ON”
position), the default network settings are not restored.

Blinking red Error occurred during the start-up of the NETA-21.
If the start-up fails, the NETA-21 restarts itself automatically after a few
seconds. During the reboot operation, all LEDs excluding the PWR LED
flash before the STAT LED turns yellow again.
If the yellow STAT LED and blinking red STAT LED alternate and the
STAT LED does not turn green, the start-up of the NETA-21 fails
continuously. Try resetting the NETA-21 to factory settings.
MON Blinking green NETA-21 sends data (eg, email) to an external destination.
Blinking red NETA-21 fails to send data (eg, email) to an external destination. Log on
to the web user interface and go to Reports –> Events for error details.
