环境：四台hp主机——2台CiscoMDS9120——2组EMC磁盘阵列
升级原因：主机重启后光纤交换机与主机相连端口自动Down掉，需要手动重启。
升级步骤：
找一台操作系统是Windows的主机
将新的版本文件与TFTP服务端程序放在一起：
m9100-s1ek9-kickstart-mz.2.0.4a.bin
m9100-s1ek9-mz.2.0.4a.bin
tftpd32.exe(这是个小巧、绿色的软件，不用配置)
执行tftpd32.exe
登陆到光纤交换机执行下面的命令：
CN_fcs_1#copy tftp://x.x.x.x/m9100-s1ek9-kickstart-mz.2.0.4a.bin bootflash:m9100-s1ek9-kickstart-mz.2.0.4a.bin
CN_fcs_1#copy tftp://x.x.x.x/m9100-s1ek9-mz.2.0.4a.bin bootflash:m9100-s1ek9-mz.2.0.4a.bin
运行tftpd32.exe 的电脑的IP地址为：x.x.x.x
结果:
CN_fcs_1#dir bootflash:
