How Do I Upgrade the Software of My Nodegrid?
Steps for the Nodegrid software upgrade via WebUI
1. Once you get the software from ZPE Systems (from your Sales representative), save the ISO file:
a. into your PC/laptop
b. into a Remote Server such as FTP, SSH, HTTP
c. into the NodeGrid, to the /var/sw directory:
i. transfer the iso file using scp - example: scp nodegrid.iso admin@nodegrid:/var/sw/
ii. copy the iso file to a USB flash drive and plug it to a Nodegrid USB port. Log in as root to Nodegrid, and go to
/run/media/sdb or /run/media/sdb1 directory. Then copy the iso file to /var/sw folder.
2. Enter the NodeGrid IP address or hostname into a browser and log in as admin
3. Go to System :: Toolkit page, and click on Software Upgrade
4. Select the Image Location:
a. Local System, if you have saved the ISO file into the /var/sw directory of the NodeGrid. Then select the filename.
b. Local Computer, if you have saved the ISO file into your PC/laptop. Then choose the file.
c. Remote Server, and enter the server's information and credentials. Note that the URL requires the following format: <PROTOCOL>://<ServerAddress>/<Remote File>. Protocols supported are FTP, TFTP, SFTP, HTTP, HTTPS, SCP. For example, ftp://192.168.160.10/nodegrid.iso or https://192.168.161.254/nodegrid.iso.
5. Then click on Upgrade button.
Downgrading
If you need to downgrade to a previous version of the Nodegrid software, two options are available:
Restore to factory default
Restore configuration
Note: To use the restore configuration option, the Nodegrid software version must match the version used to created the restoration file. Example: If the configuration file is was created in version 4.2 and Nodegrid is currently on version 5.0, Nodegrid must be downgraded to version 4.2 before the restoration file can be used.
