Software upgrade
CAUTION:
Upgrade software only when necessary and under the guidance of a technical support engineer.
Files used for upgrade
BootWare images
BootWare images are used to upgrade the BootWare program of cards, including the main processing
units (MPUs), line processing units (LPUs), and switching fabric modules. The BootWare image comprises
a basic section and an extended section.
NOTE:
Generally, there is no need to upgrade the BootWare program independently. The device uses the
shipped BootWare program. If a separate upgrade is required, do that under the guidance of an H3C
technical support engineer.
System software images
System software images are used at switch startup. The S10500 series support three types of system
software images:
• Main system software image: Used by default.
• Backup system software image: Used when the main system software image is invalid or does not
exist.
• Secure system software image: Used when the backup system software image is invalid or does not
exist. If the secure system software image is also invalid, the switch displays a failure prompt.
A system software image is an .bin file such as main.bin.
Patch package files
Patches for the S10500 switches are released in a patch package file.
A patch package file fixes certain software defects. It contains patch files for multiple cards. It enables
you to use one command to bulk-fix bugs for multiple cards.
A patch package file corresponds to the system software image version. A patch package file can only
fix defects of the corresponding system software image file, but does not add or delete any functions.
