Software Upgrade
CAUTION:
Upgrade software only when necessary and under the guidance of a technical support engineer.
Software used for upgrade
Boot ROM images
Boot ROM images are used to upgrade the Boot ROM program of cards, including the main processing
units (MPUs) and line processing units (LPUs). A Boot ROM image is a .btw file.
System software images
System software images are used at switch startup. The A7500 series support two types of system
software image:
• Main system software image: The default system software image a switch uses for startup.
• Backup system software image: The system software image a switch uses for startup when the main
system software image is invalid.
Normally, an .app file such as A7500.app is provided for upgrade, containing both the system software
image and Boot ROM image.
Patch files
Patch files are released to fix software defects. A patch file may contain one or more patches (or called
patch units). Patch files must be used together with the intended system software to fix the defects of the
latter, but not for adding or deleting features.
