Attention: Before changing any switch settings or moving any jumpers, turn off
the server; then, disconnect all power cords and external cables. See the safety
information that begins on page v. Do not change settings or move jumpers on any
system-board switch or jumper block that is not shown in this document.
Administrator password
If an administrator password is set, you must type the administrator password for
access to the full Configuration/Setup Utility menu. You can use any combination of
up to seven characters (A–Z, a–z, and 0–9) for the password.
If you forget the administrator password, you can reset it after you change the
position of the clear CMOS jumper. See “Resetting passwords” for additional
information.
Resetting passwords
If you forget the user or administrator password, you can move the clear-CMOS
jumper block on the system board to pins 2 and 3, to clear CMOS memory and
bypass the power-on or administrator password check. The jumper location is
shown in the following illustration.
To clear CMOS and reset the passwords, complete the following steps:
1. Review the safety information that begins on page v.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables.
3. Remove the server from the rack and place it on a flat, non-conductive
surface.
4. Remove the cover. See “Removing the cover” on page 18 for instructions.
5. Remove the riser-card assembly. See “Installing an adapter” on page 19 for
instructions.
6. Move the clear-CMOS jumper block from pins 1 and 2 to pins 2 and 3.
7. Install the riser-card assembly and the cover and connect the server to a
keyboard, monitor, and mouse; then, connect the server to a power source.
8. Turn on the server. You can now start the Configuration/Setup Utility program
and either delete the old password or set a new power-on or administrator
password.
