WEB-8000 - Recovering an Unreachable JACE using a N4 Clean Dist

Description:

Sometimes a JACE's platform daemon will fail to start, making it impossible to configure it using Workbench tools such as the Commissioning Wizard or Dist File Installer.

Requirements:

  1. A terminal emulator such as PuTTY
  2. A SFTP client such as FileZilla
  3. A Serial Shell Cable (Micro USB for WEB-8000)
  4. The Niagara 4 Clean Dist file for your JACE hardware
  5. A zip file utility such as 7-Zip

Procedure:

  1. Locate the Clean Dist file you wish to install on the JACE.
  2. Extract the following files from the archive (zip/n4clean.tar.gz   AND  dev/shmem/n4-xxx.image)
  3. Using PuTTY log into the Serial Shell of the JACE.
  4. Select option 4 to enable SSH/SFTP using port 22.
  5. Using an SFTP client such as FileZilla, transfer the n4clean.tar.gz file that you extracted from the clean dist file to the JACE's /zip directory. (If the transfer fails with a permissions error, issue the command tsudo chmod 777 /zip at the shell prompt and try it again)
  6. Transfer the dev/shmem/n4-xxx.image file you extracted from the clean dist file to the JACE's /dev/shmem directory.
  7. At the "#" or "$" shell prompt, issue the command osupdate. (enter another choice, sh  This will give you the "#" or "$" prompt that you need)
  8. Reboot the JACE by using the command shutdown hf 0 at the shell prompt. When the JACE restarts, it will automatically process the clean dist file.
