Baseboard Description 25
Taking the system out of secure mode does not change the state of system power. That is, if you
press and release the power switch while secure mode is in effect, the system will not power off
when secure mode is later removed. However, if the front panel power switch remains depressed
when secure mode is removed, the system will power off.
Summary of Software Security Features
Table 4 lists the software security features and describes what protection each offers. In general,
to enable or set the features listed here, the SSU must be run and configured with the Security
Menu (described in this manual on page 39.) The table also refers to other SSU menus and to the
Setup utility. For greater detail, see Chapter 2, beginning on page 27.

Feature Description
Secure mode
How to enter secure mode:
• Setting and enabling passwords automatically places the system in secure
mode.
• If a hot key combination is set (through the SSU or Setup), the system can be
secured simply by pressing the key combination. This means that the user
does not have to wait for the inactivity time-out period.
When the system is in secure mode:
• The server can boot and run the operating system, but mouse and keyboard
input is not accepted until the user password is entered.
• At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A,
the system prompts for a password. When the password is entered, the
server boots from CD or diskette and disables the secure mode.
• If there is no CD in the CD-ROM drive or diskette in drive A, the server boots
from drive C and automatically goes into secure mode. All enabled secure
mode features go into effect at boot time.
To leave secure mode, enter the correct password(s).
Disable writing to diskette In secure mode, the server will not boot from or write to a diskette unless a
password is entered. To set this feature, use the SSU Security Subsystem
Group.
To write protect access to diskette whether the server is in secure mode or not,
use the Setup main menu, Floppy Options, and specify Floppy Access as
read only.
Disable the power and
reset buttons
Power and reset buttons are always disabled when the server is in secure mode.
Set a time out period so
that keyboard and mouse
input are not accepted
Also, screen can be
blanked, and writes to
diskette can be inhibited
Specify and enable an inactivity time out period of from 1 to 120 minutes.
If no keyboard or mouse action occurs for the specified period, attempted
keyboard and mouse input will not be accepted.
The monitor display will go blank, and the diskette drive will be write protected
(if these security features are enabled through Setup or the SSU and using
onboard video).
To resume activity, enter the user password.
