page vii. Do not change settings or move jumpers on any system-board switch or
jumper blocks that are not shown in this document.

position
While the server is turned off, move the power-on password jumper from pins 1
and 2 to pins 2 and 3. You can then start the Configuration/Setup Utility program
and reset the power-on password. After you reset the password, turn off the
server again and move the jumper back to pins 1 and 2.
The power-on password override switch does not affect the administrator
password.
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. The Administrator Password choice is on the Configuration/Setup
Utility menu only if an optional IBM Remote Supervisor Adapter II SlimLine is
installed.
Attention: If you set an administrator password and then forget it, there is no way
to change, override, or remove it. You must replace the I/O board.
Installing and using the baseboard management controller utility
programs
The baseboard management controller provides environmental monitoring for the
server. If environmental conditions exceed thresholds or if system components fail,
the baseboard management controller lights LEDs to help you diagnose the
problem and also records the error in the BMC system event log.
