Procedure

Load inittab file to reset the system clock and cycle power

1. 1. Download the ‘inittab’ file attached to this technical note.
   2. Connect to the ST-IPm-8460 via serial or Ethernet.
   3. Open the Sixnet I/O Tool Kit and add the ST-IPm-8460 to the project.
   4. Go to the Operation Menu-> File Operation option select.
   5. In File Operation pop-up go to ‘/etc/’ path.
   6. Click on Load file-User File button, browse to the ‘inittab’ file that was downloaded from the bottom of this technical note. Save the file name to the station should be ‘/etc/inittab’ then click on OK. Observe the pop-up loading file into the ST-IPm-8460. Then close File operation pop-up.
   7. Cycle power (turn power off, then turn power on) to the ST-IPm-8460. This operation with the new ‘inittab’ file will reset the system clock in the ST-IPm-8460. At this point the error is resolved, but the factory installed ‘inittab’ file must be loaded back to the ST-IPm-8460. The best way to do this is to re-load the firmware file.
