IBM 2005-H16光钎交换机密码重置

1.

若factory或者root用户还是默认密码，就用这两个用户其中一个以串口登陆交换机，然后passwordadmin，根据提示就可以更改密码了，也可以直接用passwddefault命令将全部账户重置为出厂密码

admin/password

root/fibranne

factory/password

 

2.

如果密码确认都修改过了，只能通过串口连接设备，然后重新启动设备，然后前5秒按ESC，进入单用户方式进行重置

 1. Connect console cable to yourlaptop and SAN Switch

 7. Type printenv

 8. Look for the line started with OSLoader http://e.g *OSLoader=MEM()0xF0000000;*MEM()0xF08000000

 9. Copy the text between = and ; which isMEM()0xF0000000

 10. Type boot MEM()0xF0000000 �Cs

 11. Type mount -o remount,rw,noatime /

 12. Type mount /dev/hda2 /mnt

 13. Type /sbin/passwddefault
