今天一早到公司接到其它部门电话,说电脑无法打开内部系统:ERP\OA\HR\MAIL......,核心交换机业务板WS-X4612-SPF-E状态灯亮红灯,所有端口状态灯都不亮,整个公司业务瘫痪
排查思路:1、怀疑业务板卡坏了 ,无备件,晕。。。。。 2、怀疑IOS没有正确加载,因为没有备件,先是把电源关掉,把业务板卡重新安装了一次,还是无法启动,就把Console线插到引擎板上一看蒙圈了:

系统一直卡在rommon模式,并且系统寄存器值为0x2101,直接输入boot提示如下 :
rommon 1 >boot
File has bad file magic number: 0x0. Is it a valid file?
boot: can not load "bootflash:"
就查看了一下bootflah,看到IOS文件还在:

只能手动引导一下了:boot bootflah:/ cat4500e-entservices-mz_150-2_SG.bin回车后,出现一大片的###############总算松了一口气,交换机开始启动了,所有端口灯都亮起来了,输入 密码后修改寄存器值0x2102 boot system bootflash:cat4500e-entservices-mz_150-2_SG.bin do wr后网络恢复 了
把上面分享给大家
