Installing or upgrading software images
When shipped, the device is installed with a boot image, a system image, and some feature images (if
any). To upgrade the device software, you might need to perform one or more of the following tasks:
• Upgrade the boot image.
• Upgrade the system image.
• Install new feature images.
• Upgrade the existing feature images.
• Install patch images.
All these tasks can be implemented by using the install activate command. If you use this command for
