SYSTEM MANAGEMENT

This section describes functions having to do with security, power management, temperature, and
overall status. These functions are handled by hardware and firmware (BIOS) and generally
configured through the Setup utility.

4.7.1 SECURITY FUNCTIONS

This system includes various features that provide different levels of security. Note that this
subsection describes only the hardware functionality (including that supported by Setup) and
does not describe security features that may be provided by the operating system and application
software.
4.7.1.1 Power-On Password
This system includes a power-on password, which may be enabled or disabled (cleared) through a
jumper on the system board. The password is stored in configuration memory (CMOS) and if
enabled and then forgotten will require that either the password be cleared (preferable solution
and described below) or the entire CMOS be cleared (refer to section 4.6).
To clear only the password, use the following procedure:
1. Turn off the system and disconnect the AC power cord from the outlet and/or system unit.
2. Remove the cover (hood) as described in the appropriate User Guide or Service Reference
Guide. Insure that any system board LEDs are off (not illuminated).
3. Locate the password clear header labeled JCMOS1 and move the jumper from pins 1 and 2 to
pins 2 and 3.
4. Replace the cover.
5. Re-connect the AC power cord to the AC outlet and/or system unit.
6. Turn on the system. The POST routine will clear and disable the password.
7. To re-enable the password feature, repeat steps 1-6, replacing the jumper on pins 1 and 2 of
header JCMOS1.
4.7.1.2 Setup Password
The Setup utility may be configured to be always changeable or changeable only by entering a
password. The password is held on CMOS and, if forgotten, will require that CMOS be cleared
(refer to section 4.6).
