IBM xSeries 235 manual Using passwords, Power-on password, v Remote Control Security Settings

vRemote Control Security Settings

Select this choice to set a remote-control password. When you set a remote-control password, you can also set the number of failed attempts to enter the correct remote-control password, and the duration before another attempt is allowed.

For a list of supported options for your server, go to http://www.ibm.com/pc/us/compat/ on the World Wide Web. To order an optional Remote Supervisor Adapter, contact your IBM marketing representative or authorized reseller.

Using passwords

The System Security choice appears only on the full Configuration/Setup Utility menu. After you select this choice, you can implement two levels of password protection: power-on password and administrator password. The administrator password is available only if the optional IBM Remote Supervisor Adapter is installed in your server.

Power-on password

After you set a power-on password, you can enable the Unattended Start mode. This locks the keyboard and mouse but enables the operating system to start. The keyboard and mouse remain locked until you type the correct password.

You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for your power-on password. Keep a record of your password in a secure place. When a power-on password is set, POST is not completed until you type the password. If you forget the power-on password, you can regain access to the server through one of the following methods:

vIf an administrator password is set, type the administrator password at the power-on prompt. (If necessary, see “Administrator password” on page 21 for details.) Start the Configuration/Setup Utility program and change the power-on password.

vRemove the battery and then reinstall the battery (see the Option Installation Guide on the IBM xSeries Documentation CD for instructions).

vChange the position of the power-on password override switch (switch 6 on switch block 1) as described below to bypass the power-on password check. You can then start the Configuration/Setup Utility program and change the power-on password.

Notes:

1.Before changing any switch settings or moving any jumpers, turn off the server; then, disconnect all power cords and external cables. (Review the information in “Safety” on page v and “Turning off the server” on page 13.)

2.Any system-board switch or jumper blocks that are not shown in the illustrations in this book are reserved.

Power-on password override (switch 6)

Changing the position of this switch bypasses the power-on password check the next time the server is powered on. You do not need to move the switch back after the password is overridden. The default position is Off. To bypass the power-on password check, move the switch to the opposite position. Changing the position of this switch does not affect the administrator password check if an administrator password is set.
