Upload Firmware

The network jack of the PC is normally equipped with a connection LED. The LED will light up if the network connection is up. After switching on the device, this LED should light up after a few seconds. On the device itself, one of the four LEDs should light up after some seconds also. This behavior can be verified by removing and reinserting the mains plug of the device. After this test do the following steps:

1. Remove the mains plug.
2. Reinsert the mains plug.
3. Wait for approx. 2 seconds until the network LEDs light up
4. Wait for another 1-2 seconds.
5. Confirm the TFTP upload command with the enter key.

The upload should be finished after approx. 5 seconds without errors. The devices is signaling the update process by blinking the power LED. The update process should be finished after 2 minutes at the latest. The device will startup the new firmware automatically.

The firmware upload was aborted.

Please upload a suitable *.bin or *.trx firmware file.

Firmware upload was cancelled.

A new firmware can be uploaded only in failsafe or read-only mode. On the Restart page activate the desired option and confirm with Restart. Upload the firmware on this page after the restart.
