Technical Product Specification

Intel® Server Boards S4600LH2/T2 TPS
Revision 2.0
106
Note: If the ME FRC UPD jumper is moved with AC power applied, the ME will not operate
properly. The system will need have the AC power cords removed, wait for at least 10 seconds and
then reinstalled to ensure proper operation.
9. Install AC power cords
10. Power on system
D – 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 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 and unplug the power cords.
2. Move jumper (J73) from the default (pins 1 and 2) operating position to the password clear position
(pins 2 and 3).
3. Close the server chassis and reattach the power cords
4. Power up the server and wait until POST completes.
5. Power down the server and unplug the power cords.
6. Open the chassis, and move the jumper back to the default position (covering pins 1 and 2).
7. Close the server chassis and reattach the power cords.
8. Power up the server
E – BIOS Default Jumper Block
This jumper resets BIOS Setup options to their default factory settings. This action is the same as clearing
CMOS.
1. Power down the server and unplug the power cords
2. Move BIOS DFLT jumper (J75) from the default (pins 1 and 2) position to the Set BIOS Defaults
position (pins 2 and 3)
3. Wait 5 seconds then move the jumper back to the default position of pins 1 and 2
4. Install riser card assembly
5. Install Power Cords
6. Power on system
F – BMC Force Update Jumper Block
The BMC Force Update jumper is used to put the BMC in Boot Recovery mode for a low-level update. It
causes the BMC to abort its normal boot process and stay in the boot loader without executing any Linux code.
The jumper is normally in the de-asserted position. The system must be completely powered off (A/C power
removed) before the jumper is moved. After power is re-applied and the firmware update is complete, the
system must be powered off again and the jumper must be returned to the de-asserted position before normal
operation can begin.
