图1-1 通过boot-loader命令升级流程图

 

1.1.2  升级过程

1. 升级前准备

请按“软件升级前准备”章节内容完成升级前的准备。

2. 下载软件包

从PC上下载升级所需的软件到设备。下载软件的详细介绍请参见“附录A 下载升级软件”章节。

3. 升级启动软件

 

# 将IPE文件指定为主用启动软件。

<Sysname> boot-loader file flash:/all.ipe all main

Verifying the file flash:/all.ipe on slot 1..............Done.

US700 images in IPE:

  boot.bin

  system.bin

This command will set the main startup software images. Continue? [Y/N]:y
