Bypassing an Unknown Power-on Password
When a power-on password is set, the POST does not complete
until you enter the password. If you forget the power-on password,
you can regain access to the server in the following ways:
Ÿ
Enter the administrator password at the power-on prompt. Start
the Configuration/Setup utility programs and change the
power-on password. See “Using the Power-on Password Menu”
on page 31.
Ÿ
Change the position of the power-on password jumper. When
you restart the server, POST proceeds without prompting for the
password for this startup only. Start the Configuration/Setup
utility programs and set a new power-on password.
Before you begin
Ÿ Read “Electrical Safety” on page 53 and “Handling
Static-Sensitive Devices” on page 54.
Ÿ
Turn off the server.
Ÿ Disconnect all external cables and power cords, and then
remove the server cover (see “Preparing to Add Options” on
page 55).
1. Locate the power-on password jumper (J12).
2. Change the jumper's position:
a. Lift the jumper straight off the pin block.
b. Align the holes in the bottom of the jumper with the center
pin and the pin that was not covered previously.
