4	Console连接到Slot 1设备上，将升级完成后的Slot 1设备中的业务端口全部undo  shutdown打开。 [ASW-T06-I03.CM3]interface range Ten-GigabitEthernet 1/0/1 to Ten-GigabitEtherne t 1/0/48 [ASW-T06-I03.CM3-if-range]undo shutdown 注意： 此处切勿保存配置!
5	Console连接到Slot 2设备上，指定启动文件为R2208P01，重启slot 2升级版本；、 <ASW-T06-I03.CM3>boot-loader file flash:/S5820V2_5830V2-CMW710-R2208P01.ipe slot 2 main <ASW-T06-I03.CM3>reboot slot 2 Start to check configuration with next startup configuration file, please wait.........DONE!
