Press RETURN to get started! 七注意事项： 1路径和目标文件不一致问题 在升级过程中一定要小心，在敲命令行的时候特别要仔细，特别是在改启动路径的时候，如果启动路径的文件和flash里面的IOS不相同的话，是启动不了。解决方案 a 在switch模式下，查看系统启动路径的全称 Interrupt within 5 seconds to abort boot process. Boot process failed... The system is unable to boot automatically. The BOOT environment variable needs to be set to a bootable image. switch: set ASSEMBLY_REVISION_NUM=B0 BOOT=flash:c3550-smi.bin MAC_ADDR=00:04:4D:72:87:C0 MODEL_NUM=WS-C3524-XL-EN MODEL_REVISION_NUM=A0
