The power-on password override jumper does not affect the administrator
password.
Attention: Before you move any jumpers, turn off the server; then, disconnect
all power cords and external cables. See the safety information that begins with
“Safety” on page v. Do not change settings or move jumpers on any
system-board switch or jumper blocks that are not shown in this document.
Administrator password
This topic provides general information about the administrator password.
If an administrator password is set, you must type the administrator password for
access to the full Setup utility menu. You can use any combination of 6-20
printable ASCII characters for the password.
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.
