Firmware Recovery

When the LEDs that indicate FAULT, Signal Strength and WLAN all light up simultaneously and blink at

one-second intervals, it means that the system boot up process has failed. This might result from some wrong

operation or issues such as an unexpected shutdown during firmware update. The AWK-1131A is designed to

help administrators recover from such damage and resume system operation rapidly.

First, connect to the AWK-1131A’s RS-232 console with the settings 115200 bps and N-8-1. A message is

displayed on the terminal emulator at one-second intervals as shown below:

please set-up TFTP server 192.168.127.1 contains awk1131a.rom for firmware recovery.

To recover the firmware, do the following:

1. Change the IP address of the laptop to 192.168.127.1.

2. Set up a TFTP server in your laptop.

3. Download AWK-1131A's firmware from Moxa Website

4. Change firmware file name to awk1131a.rom

5. Connect to the AWK-1131A's RJ45 Ethernet port

If the settings are correct, the following message is shown on the terminal emulator. The AWK-1131A will

reboot when the firmware recovery process is complete.
