System Support

Power-On / Setup Password

These systems include a power-on and setup passwords, which may be enabled or disabled (cleared) through a jumper on the system board. The jumper controls a GPIO input to the SB700 that is checked during POST.

To clear the Power-On and/or Setup 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 Maintainance And Service Reference Guide. Insure that all system board LEDs are off (not illuminated).

3.Locate the password clear jumper (header is colored green and labeled E49 on these systems) and move the jumper from pins 1 and 2 and place on (just) pin 2 (for safekeeping).

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 E49.

The Setup utility may be configured to be always changeable or changeable only by entering a password. Refer to the previous procedure (Power On / Setup Password) for clearing the Setup password.

Cable Lock Provision

These systems include a chassis cutout (on the rear panel) for the attachment of an optional cable lock mechanism.

I/O Interface Security

The SATA, serial, parallel, USB, and diskette interfaces may be disabled individually through the Setup utility to guard against unauthorized access to a system. In addition, the ability to write to or boot from a removable media drive (such as the diskette drive) may be enabled through the Setup utility. The disabling of the serial, parallel, and diskette interfaces are a function of the SIO controller. The USB ports are controlled through the SB700.
