S6850 console密码忘记，如何在不丢配置的情况下重新进入设置
组网及组网描述：
telnet或者ssh能登吗？telnet和ssh能登的话，进去改，这两个不行的话就只能重启进CTRL b
参考：
一、 组网：
无
二、 问题描述：
客户S7500E以太网交换机长期未通过console口登录，忘记了设置的console口登录口令，导致无法登录交换机。
三、 过程分析：
在配置了telnet的情况下，我们可以通过telnet方式登录到设备上，修改或者重新设置console口的登录口令。
如果没有配置telnet或者telnet登录之后用户权限不够，则只能通过删除配置文件的方式恢复对设备的控制权。
四、 解决方法：
如果用户设置的console登录口令丢失，又不能通过telnet方式修改口令，可以使用以下解决方法：删除启动文件。具体操作步骤如下：
1. 进入BOOTROM菜单
