如果是新的交换机安装，可以使用账户/密码admin/adminProblem Description
Customer is not able to login to the BL p-Class GbE2 switch using the
Serial port, because the password is not known or forgotten.
There is no "Default" password.
NOTE - If this is a new install the initial Username/Password is
admin/admin.
Resolution/Workaround
All p-Class GbE2 switches have the same backdoor password. This
password (listed below) ONLY works from the local serial port on the
switch. This means the customer must have physical access to the
switch. This process cannot be used via Telnet or the Web Interface.
The password is used to reset the Administrator password so they can
login as the administrator.
如果是忘记了密码需要重设，可以使用后门账户/密码Resolution/Workaround
针对所有p级别的GbE2交换机均适用
只能从本地连接交换机串口，意味着必须可以接触到交换机，不能远程telnet或web界面操作
该后门密码可以用来重设管理员密码
