升級準備
1、升級工具
筆記本電腦、Console線纜、網線、螺絲刀
2、軟件
TFTP軟件：3CDaemon
IOS軟件：
cat4000-i5s-mz.122-25.EWA14.bin （大小：12115KB,需要交換機256M DRAM,32M FLASH支持運行）
升級步驟
1、關閉交換機電源，使用螺絲刀拆卸下一塊引擎WS-X4515後重啓交換機，交換機處於單引擎運行狀態；
2、根據交換機bootflash的存儲情況，當前剩餘的存儲空間不夠存儲新的IOS軟件，首先使用以下命令刪除當前bootflash下未用的IOS軟件：
XIASW#delete bootflash:cat4000-i9s-mz.122-25.EWA4.bin |
3、將筆記本電腦使用網線和交換機互聯，並配置同一網段的IP地址，確保筆記本電腦和交換機可以PING通，在筆記本運行TFTP軟件，配置TFTP軟件制定新IOS軟件的位置；
4、在交換機上輸入以下命令將新 IOS軟件上傳至bootflash：
XIASW#copy tftp://192.168.1.1/ cat4000-i5s-mz.122-25.EWA14.bin bootflash: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! [OK - 12115 Kbytes] 備註：192.168.1.1是筆記本電腦IP地址； |
5、新IOS軟件上傳完畢後，在交換機配置模式下輸入以下命令修改交換機IOS軟件的啓動選擇：
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 ----------//保存修改後的配置 |
6、重新啓動交換機，如果交換機不能使用新IOS軟件正常啓動，則終止IOS軟件升級，修改交換機以下命令使用原IOS啓動：
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 ----------//保存修改後的配置 |
如果交換機可以使用新的IOS軟件正常啓動，則繼續下一步操作；
7、關閉交換機電源，將IOS軟件升級好的引擎WS-X4515使用螺絲刀拆卸下來，將備引擎安裝到交換機的引擎槽位，加電啓動交換機，依次按照第2步至第6步完成備引擎的IOS軟件升級；
8、備引擎使用新IOS軟件升級完畢後，關閉交換機電源，將主備引擎全部安裝至交換機的兩個引擎槽位，交換機加電啓動後輸入以下命令檢查主備引擎的故障切換：
XIASW#redundancy force-switchover |
觀察如果主備引擎可正常切換，則交換機IOS軟件升級完畢。
注意事項
1、主備引擎的安裝和拆卸必須在關閉交換機電源後進行；
2、IOS軟件升級完畢後及時檢查交換機的配置，並進行網絡應用的測試；
