BIOS Security Features
The SE7500CW2 server BIOS provides a number of security features. This section describes
the security features and operating model.
Note: The SE7500CW2 server board has the ability to boot from a device attached to the USB
port, such as a floppy disk, disk drive or CD-ROM, or ZIP* drive, even if it is attached through a
hub. The security model is not supported when booting to a USB device.

Password Protection
The BIOS uses passwords to prevent unauthorized tampering with the system. Once secure
mode is entered, access to the system is allowed only after the correct password(s) has been
entered. Both the user and Supervisor passwords are supported by the BIOS. User password
can only be set with the Supervisor priority. The maximum length of the password is eight
characters. The password cannot have characters other than alphanumeric (a-z, A-Z, 0-9). The
user and supervisor passwords are not case sensitive.
Once set, a password can be cleared by changing it to a null string. Entering the user password
allows the user to modify the time, date, user password, secure mode timer, and secure mode
hot-key setup fields. Other setup fields can be modified only if the supervisor password is
entered. The user password also allows the system to boot if secure boot is enabled. If only one
password is set, this password is required to enter Setup. The supervisor has control over all
fields in the setup including the ability to clear user password.
If the user enters three wrong passwords in a row during the boot sequence, the system will be
placed into a halt state. This feature makes it difficult to break the password by "trial and error"
method. When entering a password, the backspace key is accepted as a character of the
password.
