How to restore the default BootROM password for S series switches

To restore the BootROM password on S series switches (except S1700 switches), use one of the following methods:
1. For V200R001 or later, run the reset boot password command in the user view to reset the BootROM password to the default.
By default,
For S series fixed switches running a version earlier than V100R006C03, the default BootROM password is huawei; for fixed switches running V100R006C03 or a later version, the default BootROM password is Admin@huawei.com.
For S7700&S9700&S12700&S9300 switches running V100R006C00 or an earlier version, the default BootROM password is 9300; for S7700&S9700&S12700&S9300 switches running a version later than V100R006C00, the default BootROM password is Admin@huawei.com.
2. For switches running V200R007 or a later version, choose Enter password submenu in the BootROM menu to access the password submenu. Select Reset BootROM password in the password submenu to restore the default BootROM password.
3. For modular switches with dual MPUs:
a. If the software version is V200R005 or later, run the reset boot password command to restore the default BootROM password on both the active and standby MPUs.
b. If the software version is V200R003 or earlier, run the reset boot password command to restore the default BootROM password on only the active MPU. Then perform an active/standby MPU switchover, and run the reset boot password command to restore the default BootROM password on the original standby MPU. You are advised to perform an active/standby MPU switchover during off-peak hours.
