System BIOS
3.9.2
Password Protection
The BIOS uses passwords to prevent unauthorized tampering with the server setup. Both user
and administrator passwords are supported by the BIOS. An Administrator password must be
entered in order to set the user password. The maximum length of the password is seven
characters. The password cannot have characters other than alphanumeric (a-z, A-Z, 0-9). It is
not case sensitive.
Once set, a password can be cleared by changing it to a null string. Entering the user password
will allow the user to modify the time, date, and user password. Other setup fields can be
modified only if the administrator password is entered. If only one password is set, this
password is required to enter BIOS Setup.
The administrator has control over all fields in BIOS Setup, including the ability to clear the user
password.
If the user or administrator enters an incorrect password three times in a row during the boot
sequence, the system is placed into a halt state. A system reset is required to exit out of the halt
state. This feature makes it difficult to break the password by guessing at it.
3.9.3
Password Clear Jumper
If the user and/or administrator password is lost or forgotten, both passwords may be cleared by
moving the password clear jumper into the clear position. The BIOS determines if the password
clear jumper is in the clear position during BIOS POST and clears any passwords if required.
The password clear jumper must be restored to its original position before new passwords can
be set.
