Meaning
No SD/SDHC card
Card attached and taken into use
Card attached and initialization in progress
Card can be safely removed
Card attached, removal in progress
Together with the blinking red STAT LED: System waits for confirmation of reboot
operation or network override
Card error, for example write protection prevents from writing data to the card
Card initialization failed. Unsupported card type (eg, SDXC and MMC cards are not
supported).
No devices (no wire) connected to the PNL port
All devices connected, identified and commissioned
Manual or automatic discovery of devices in progress
Communication OK, but device connectivity limited.
All devices are ready to be unplugged/disconnected.
Communication error caused the panel port network initialization to fail.
Unknown device in the network, or something interfering the network and preventing
proper detection of monitored devices.
Unsupported device found in the network, or too many devices in the network to be
monitored
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.
Connection set up and in operation, for example, DHCP is active and at least one PC
has got an IP-address
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.
At least one user has been logged on to the user interface
Factory-level access/operation. Firmware update in progress.
Note: System status (STAT LED) blinks during the firmware update.
Power off
Power on
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.
System in operation, OK
System starts up, services not yet fully operational
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.
Firmware update in progress
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
NETA-21 sends data (eg, email) to an external destination.
NETA-21 fails to send data (eg, email) to an external destination.
