Appendix B Upgrading software

CAUTION:
Do not power off or reboot the device during the upgrade process.
The software upgrade procedure is the same for all security devices. This chapter describes how to
upgrade software from the CLI, Web interface, and BootWare menus. The default storage medium
varies by device model. This chapter uses the CF card as the default storage medium.

Software images

Software images types

The following software types are available:

BootWare image—A .btw file that contains a basic segment and an extended segment. The
basic segment is the minimum code that bootstraps the system. The extended segment
enables hardware initialization and provides system management menus. You can use these
menus to load software and the startup configuration file or manage files when the device
cannot start up correctly.

System software image—Includes the following image subcategories:
Boot image—A .bin file that contains the Linux operating system kernel. It provides process

management, memory management, file system management, and the emergency shell.
System image—A .bin file that contains the Comware kernel and standard features,

including device management, interface management, configuration management, and
routing.
Patch image—A .bin file that is released for fixing bugs without rebooting the device. A

patch image does not add or remove features.
You can assign the following attributes to a system software image:
Main—The image is the primary image. The system always attempts to load the main

image at startup in preference to the backup image.
Backup—The image is the backup image. It is used only if the primary image is corrupt or

not available.

Software release forms

Software images are released in one of the following forms:

Separate .bin files. You must verify compatibility between software images.

As a whole in one .ipe package file. The images in an .ipe package file are compatible. The
system decompresses the file automatically, loads the .bin images and sets them as startup
software images.
Features
the Web interface.
Support for SNMPv3 and compatibility with SNMPv2C and SNMPv1.
NTP time synchronization.
