console登录无线AP要密码。
如何恢复华为AP4050DN-E
4:室内低密度
0:内置天线1外置天线
5：第二代AC产品
0：预留位
D:双频
N：普通天线E：智能天线
二、解决办法
第一种解决办法：长按Default按钮
如果所有密码均遗忘，对于有Default按钮的设备，可以长按Default按钮3s以上恢复出厂配置，设备的用户名和密码将恢复为缺省值；对于没有Default按钮的设备，请看以下解决办法。
可以直接恢复出厂设置。
修改完密码后，一定要保存。
第二种破解方法：在BIOS下配置跳过Console口密码启动后，重新设置Console口密码
设备的BIOS提供了配置跳过Console口密码启动的功能，可以在用户使用Console口登录的时候跳过密码检查。这样系统启动后除了不需要输入Console密码外，与正常启动相同，也会完成所有配置加载。设备启动后修改Console口密码，然后保存配置。
跳过密码检查存在安全风险，请务必保存好您的BootROM密码。
要进入到BIOS菜单需要重启设备，会导致业务中断，请视具体情况做好设备数据备份，并尽量选择业务量较少的时间操作。
清空Console口密码登录后请马上配置新的密码，否则登录超时或重启后，仍需要清空密码来登录。
在此操作过程中不要对设备进行下电。
用串口线连接并重启设备，出现“Press CTRL+B to enter BIOS menu”打印信息时，按下“Ctrl+B”并键入密码后进入BIOS主菜单。
用串口线连接设备的方法请参见通过Console口连接设备。
不同版本的BootROM密码可能不同，具体可参见AC和AP的缺省用户名和密码。
配置跳过Console口密码登录。
输入BIOS菜单中“Clear password for console user”对应的序号，清除Console口密码。
输入BIOS菜单中“Boot with default mode”对应的序号，以缺省模式启动设备。
完成系统启动后，通过Console口登录时不需要认证，登录后修改Console口密码。此处以登录认证模式为password模式，密码为“huawei 123”为例。
不同版本中设置本地验证密码的命令有所不同：
<Huawei>system-view[Huawei]user-interface console 0[Huawei-ui-console0]authentication-mode password[Huawei-ui-console0]set authentication password cipher Enter Password
<6-16>
://此处提示信息以设备实际显示为准
Confirm Password:
[Huawei-ui-console0]return
V200R002及之前版本：set authentication password[cipher password]
V200R003及之后版本：set authentication password cipher
为了防止重启后配置丢失，执行save命令保存配置。
