S2750&S5700&S6700 Series Ethernet Switches Troubleshooting: How to
Recover the BootROM Password? Below will give you the answer:
The BootROM is
the basis for device security and maintenance, which provides the functions such
as configuration recovery and system software upgrade. You must keep the
BootROM password secure. If the BootROM password is lost, you can run the reset
boot password command to restore the default password and reset a password.
To reset the
BootROM password through the BootROM menu, you must connect to the console port
and log in to the device through the console port.
1. In any view,
restore the default BootROM password Admin@huawei.com.
<HUAWEI>

to enter the boot menu by clicking Ctrl+B will be restored
To the default
password, continue? [Y/N] y

in setting password of boot to "Admin@huawei.com".
NOTE
The
reset boot password command is only supported by versions later than V200ROO1
(including V200ROO1). The default password for versions earlier than V200R001
is huawei9300.
2. The default
password is not secure and must be changed.

the BootROM password using either of the following methods:
