6.2.2.1 BIOS Default Jumper Block
This jumper resets BIOS options, configured using the <F2> BIOS Setup Utility, back to their original default
factory settings.
Note: This jumper does not reset Administrator or User passwords. In order to reset passwords, the
Password Clear jumper must be used
1. Power down the server and unplug the power cord(s)
2. Remove the system top cover and move the “BIOS DFLT” jumper from pins 1 - 2 (default) to pins 2 - 3
(Set BIOS Defaults)
3. Wait 5 seconds then move the jumper back to pins 1 - 2
4. Re-install the system top cover
5. Re-Install system power cords
Note: The system will automatically power on after AC is applied to the system.
6. During POST, access the <F2> BIOS Setup utility to configure and save desired BIOS options
Note: After resetting BIOS options using the BIOS Default jumper, the Error Manager Screen in the <F2> BIOS
Setup Utility will display two errors:
0012 System RTC date/time not set
5220 BIOS Settings reset to default settings
Note: also that the system time and date may need to be reset.
6.2.2.2 Password Clear Jumper Block
This jumper causes both the User password and the Administrator password to be cleared if they were set.
The operator should be aware that this creates a security gap until passwords have been installed again
through the <F2> BIOS Setup utility. This is the only method by which the Administrator and User passwords
can be cleared unconditionally. Other than this jumper, passwords can only be set or cleared by changing
them explicitly in BIOS Setup or by similar means. No method of resetting BIOS configuration settings to
default values will affect either the Administrator or User passwords.
1. Power down the server. For safety, unplug the power cord(s)
2. Remove the system top cover
3. Move the “Password Clear” jumper from pins 1 - 2 (default) to pins 2 - 3 (password clear position)
4. Re-install the system top cover and re-attach the power cords
5. Power up the server and access the <F2> BIOS Setup utility
6. Verify the password clear operation was successful by viewing the Error Manager screen. Two errors
should be logged:
5221 Passwords cleared by jumper
5224 Password clear jumper is set
7. Exit the BIOS Setup utility and power down the server. For safety, remove the AC power cords
8. Remove the system top cover and move the “Password Clear” jumper back to pins 1 - 2 (default)
9. Re-install the system top cover and reattach the AC power cords.
10. Power up the server
11. Strongly recommended: Boot into <F2> BIOS Setup immediately, go to the Security tab and set the
Administrator and User passwords if you intend to use BIOS password protection
