32 Boardset Description
Boot Without Keyboard
The server can boot with or without a keyboard. Before it boots, BIOS displays a message
keyboard detection. During POST, BIOS automatically detects and tests the keyboard if one is
present.
Locked Power and Reset Switches
The power and reset push-button switches on the front panel are locked when the server is in
secure mode. To exit from the secure mode, you must enter your user password.
Diskette Write Protect
If Diskette Write Protect is enabled in Setup, it write-protects the diskette drive only while the
server is in the secure mode. To exit secure mode, enter your user password.
Video Blanking
If Video Blanking is enabled in Setup, the video display will be off when the server is in secure
mode. To exit secure mode, enter your user password.
Emergency Management Port (EMP)
The EMP is a feature of server management. EMP lets the front panel controller (FPC)
communicate with the server via the serial port even if the server power is off. To restrict
EMP access, you can enable an administrator password in Setup. If the administrator enters a new
EMP password or clears an old one, BIOS sends the appropriate command via the I
2
C bus
interface to the FPC. To change the password from Setup again, enter the new password twice.
If the administrator sets the Password Clear switch to the Clear position, BIOS clears the
administrator and user passwords (to change switches, see “Configuration Switches” on page 182).
It also attempts to clear the EMP password. If the FPC is not present or is not functioning
properly, BIOS times out and continues.
