Setting the password override jumper, Disabled

Page 61 highlights

The keyboard and mouse remain locked until you enter the correct password. You can use any combination of up to seven characters (A- Z, a-z, and 0-9) for the power-on password. Keep a record of the password in a secure place. If you forget the poweron password, you can regain access to the server by removing the battery and then installing the battery, or by overriding or bypassing the power-on password; see "Setting the password override jumper". Setting the password override jumper: When a power-on password is set, POST does not complete until you enter the password. If you forget the power-on password, you can regain access to the server through either of the following methods: • Enter the administrator password at the power-on prompt, if an administrator password has been set. (See "Administrator password" on page 50 for details.) Start the Configuration/Setup Utility program and change the power-on password. See "Power-on password" on page 48. • Change the position of the jumper on J15 to bypass the power-on password check. You can then start the Configuration/Setup Utility program and change the poweron password. See "System board component locations" on page 54 for the location of J15. Notes: 1. Turn off the server, and disconnect all power cords before moving any jumpers. 2. Jumpers J19 and J3 are located on the same jumper block as jumper J15 on the system board. These jumpers are set to Disabled. Do not change the settings on these jumpers. Attention: If you change the settings on these jumpers, the server will fail. Jumper name Description J15 Power-on password override Changing the position of this jumper bypasses the power-on password check if the jumper has been moved since the server was last powered on. You do not need to move the jumper back to the default position after the password is overridden. The default position is a jumper on pins 1 and 2. Changing the position of this jumper does not affect the administrator password check if an administrator password is set. Table 7.

Configuring the server
49
The keyboard and mouse remain locked until you enter the
correct password.
You can use any combination of up to seven characters (A–
Z, a–z, and 0–9) for the power-on password.
Keep a record
of the password in a secure place.
If you forget the power-
on password, you can regain access to the server by remov-
ing the battery and then installing the battery, or by overrid-
ing or bypassing the power-on password; see “Setting the
password override jumper”.
Setting the password override jumper:
When a
power-on password is set, POST does not complete until
you enter the password.
If you forget the power-on pass-
word, you can regain access to the server through either of
the following methods:
Enter the administrator password at the power-on
prompt, if an administrator password has been set.
(See “Administrator password” on page 50 for details.)
Start the Configuration/Setup Utility program and
change the power-on password.
See “Power-on pass-
word” on page 48.
Change the position of the jumper on J15 to bypass the
power-on password check.
You can then start the Con-
figuration/Setup Utility program and change the power-
on password.
See “System board component loca-
tions” on page 54 for the location of J15.
Notes:
1.
Turn off the server, and disconnect all power cords
before moving any jumpers.
2.
Jumpers J19 and J3 are located on the same jumper
block as jumper J15 on the system board.
These jump-
ers are set to
Disabled
.
Do not change the settings
on these jumpers.
Attention:
If you change the settings on these jump-
ers, the server will fail.
For more information on jumper locations, see “Changing
jumper positions” on page 85.
Jumper name
Description
J15 Power-on
password override
Changing the position of this jumper
bypasses the power-on password
check if the jumper has been moved
since the server was last powered
on.
You do not need to move the
jumper back to the default position
after the password is overridden.
The default position is a jumper on
pins 1 and 2.
Changing the position of this jumper
does not affect the administrator
password check if an administrator
password is set.
