软件工具上的准备：准备好TFTP和相应的ios
运行中的H3C S5500 Series交换机系统升级操作
运行中的交换机在FALSH不足以考入新的软件时适用本方法速度速度比较慢
1、H3C S5500
（系统进入完成）
2、进入System View（系统视界）界面
<H3C>system-view
3、为交换机添加IP
[H3C]interface Vlan-interface 1 （回车进入Vlan-interface1设置）
[H3C-Vlan-interface1]ip address 1.1.1.2 255.0.0.0
（因为我的本机IP是1.1.1.1所以添加为IP1.1.1.2 还要设置子网掩码我这里的是255.0.0.0 然后回车）
上面显示交换机IP设置完成
4、下面我们来PING以下我的计算机，确认网络连接已建立
[H3C-Vlan-interface1]ping 1.1.1.1 （交换机1.1.1.2 PING 1.1.1.1）
PING 1.1.1.1: 56
data bytes, press CTRL_C to break
Reply from 1.1.1.1: bytes=56 Sequence=1 ttl=128 time=6 ms
通讯正常
5、配置PC上的tftp服务
6、在交换机系统视界下敲,通过TFTP从1.1.1.1 （我的计算机）获取系统文件
<H3C>tftp 1.1.1.1 get S5500EI-CMW520-R2208-S168.bin
File will be transferred in binary mode Downloading file from
remote TFTP server, please
wait...........................................................................................................................
TFTP: 12397691 bytes received in 612 second(s)
File downloaded successfully.
获取完成
7、将获取成功的文件定义为主系统文件
[H3C]quit 退出到系统底层< 括号>表示使用boot-loader 命令操作
boot-loader file
flash:/s5500ei-cmw520-r2208-s168.bin slot 1 main
定义插槽1中闪存的文件s5500ei-cmw520-r2208-s168.bin 为主（main）
This command will set the boot file of the specified board.
Continue? [Y/N]:y 回车
The specified file will be used as the main boot file at the next
reboot on slot 1!
quit
