Upgrading Software Images
Upgrading Software Images
The VG248 has two software images: a main software image and a boot loader.
If necessary, you can upgrade these software images.
Upgrading the Main Image
The main software image might need to be updated if a new release is available
on CCO as a bug update or feature enhancement.
Caution When you send a new software image to the VG248 using FTP, the
current image is automatically deleted. If the FTP transfer
terminates before the new file is copied to the VG248, the VG248
might not be able to start up. See the “Resolving an Incomplete
Upgrade” section on page 6-15 to resolve this problem.
To upgrade the main software image, perform these steps:
Step 1 Obtain a configuration file whose name is in the following format:
vgc-main.<version>.tar, where <version> indicates the release number, such as
1-0-1.
Step 2 Connect to the VG248 using FTP.
Step 3 Send the configuration file to the VG248 using FTP.
Step 4 Restart the VG248 for the new image to take effect.
Step 5 From the main menu on the VG248, choose Display.
Step 6 Choose Version to verify the updated version has been installed.
