升级准备
1、升级工具
笔记本电脑、Console线缆、网线、螺丝刀
2、软件
TFTP软件：3CDaemon
IOS软件：
cat4000-i5s-mz.122-25.EWA14.bin （大小：12115KB,需要交换机256M DRAM,32M FLASH支持运行）
升级步骤
1、关闭交换机电源，使用螺丝刀拆卸下一块引擎WS-X4515后重启交换机，交换机处于单引擎运行状态；
2、根据交换机bootflash的存储情况，当前剩余的存储空间不够存储新的IOS软件，首先使用以下命令删除当前bootflash下未用的IOS软件：
|
XIASW#delete bootflash:cat4000-i9s-mz.122-25.EWA4.bin |
3、将笔记本电脑使用网线和交换机互联，并配置同一网段的IP地址，确保笔记本电脑和交换机可以PING通，在笔记本运行TFTP软件，配置TFTP软件制定新IOS软件的位置；
4、在交换机上输入以下命令将新 IOS软件上传至bootflash：
|
XIASW#copy tftp://192.168.1.1/ cat4000-i5s-mz.122-25.EWA14.bin bootflash: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! [OK - 12115 Kbytes] 备注：192.168.1.1是笔记本电脑IP地址； |
5、新IOS软件上传完毕后，在交换机配置模式下输入以下命令修改交换机IOS软件的启动选择：
|
XIASW（config）#no boot system flash bootflash:cat4000-i5s-mz.122-25.EWA7.bin XIASW（config）#boot system flash bootflash:cat4000-i5s-mz.122-25.EWA14.bin XIASW#write ----------//保存修改后的配置 |
6、重新启动交换机，如果交换机不能使用新IOS软件正常启动，则终止IOS软件升级，修改交换机以下命令使用原IOS启动：
|
XIASW（config）#no boot system flash bootflash: cat4000-i5s-mz.122-25.EWA14.bin XIASW（config）#boot system flash bootflash:cat4000-i5s-mz.122-25.EWA7.bin XIASW#write ----------//保存修改后的配置 |
如果交换机可以使用新的IOS软件正常启动，则继续下一步操作；
7、关闭交换机电源，将IOS软件升级好的引擎WS-X4515使用螺丝刀拆卸下来，将备引擎安装到交换机的引擎槽位，加电启动交换机，依次按照第2步至第6步完成备引擎的IOS软件升级；
8、备引擎使用新IOS软件升级完毕后，关闭交换机电源，将主备引擎全部安装至交换机的两个引擎槽位，交换机加电启动后输入以下命令检查主备引擎的故障切换：
|
XIASW#redundancy force-switchover |
观察如果主备引擎可正常切换，则交换机IOS软件升级完毕。
注意事项
1、主备引擎的安装和拆卸必须在关闭交换机电源后进行；
2、IOS软件升级完毕后及时检查交换机的配置，并进行网络应用的测试；
