Unity reset procedure

1. Take a usb key/external hard disk.

   (The device must be formatted in FAT32 or ext2-4).

2. Create the file “ esia_unity_reset.txt “containing the following line :

   copy

   code=31c2a41ec61f3603587178027e7dc6bc791fa173

3. Plug in the usb key/disk containing the file ” esia_unity_reset.txt “on the unity (you can choose between 4 usbs locations).

4. Wait at least 15 seconds before disconnecting the disk from the unity. After 2 minutes, the unity will be reset. Even if there is no apparent reaction from the unit, it will automatically be reset internally.

5. If your disk is in rw mode, an ” esia_unity_reset.log “will appear on it next to the esia_unity_reset.txt ”

• This works with USB sticks and any drive with an external power supply. If your drive is self-powered, the unity power supply may not be able to supply enough power to both devices (unity + drive).
• Check that the ” esia_unity_reset.txt “is located on a FAT32 or Linux (ext2-4) partition. It will not work with an NTFS formatted partition.
• If you are using windows and the « Extensions de noms de fichiers >If you are using Windows and the > is not activated, when you right-click ⇒ New ⇒ Text document, do not add .txt to the filename, otherwise the result will be : « esia_unity_reset.txt.txt » . This will not work. To be sure of avoiding this problem, we advise you to check the box « Extensions de noms de fichiers » box in the « Affichage » tab of Windows Explorer.

By default, the procedure configures the unit with its initial network configuration and then reboots it. However, you can add parameters (system and reset) to the ” esia_unity_reset.txt “file in order to change the way it normally works and thus have this in our :

copy

# Needed
code=31c2a41ec61f3603587178027e7dc6bc791fa173
 
# Default = restart, can be none, restart, shutdown
system=none
 
# Default = yes, can be no
reset=yes

In the example above, the unity will return to its default configuration and reconfigure its network parameters (parameter reset) without rebooting the unity (parameter system).
