Intel® Server D50TNP Family Integration and Service Guide
D.4 BMC Force Update Jumper (BMC_FRC_UPDT – J2X4)
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. This
jumper should only be used if the BMC firmware has become corrupted and requires reinstallation.
Note: The BMC firmware update files are included in the SUP posted to Intel's download center. See
Table 1.
To use the BMC force update jumper, perform the following steps:
1. Power down the Intel® D50TNP Module.
2. Remove the module from the chassis
3. Remove the riser assemblies from the module.
4. Move the "BMC FRC UPDT" (J2X4) jumper from pins 1–2 (default) to pins 2–3 (force update position).
5. Reinstall the riser assemblies
6. Reinstall the module in the chassis.
7. Power on the module.
8. Boot to the EFI shell.
9. Change directories to the folder containing the update files.
10. Update the BMC firmware using the following command:
sysfwupdt.efi -u <filename.bin>
11. When the update has successfully completed, power down the module.
12. Remove the module from the chassis and remove the riser assemblies from the module.
13. Move the "BMC FRC UPDT" (J2X4) jumper back to pins 1–2 (default).
14. Reinstall the riser assemblies
15. Reinstall the module in the chassis.
16. Power on the module.
17. Boot to the EFI shell.
18. Change directories to the folder containing the update files.
19. Reinstall the board/system SDR data by running the FRUSDR utility.
20. After the SDRs have been loaded, reboot the module.
D.5 BIOS SVN Downgrade (SVN_Bypass – J16)
The BIOS SVN Downgrade Jumper is labeled SVN_BYPASS on the server board. When this jumper is moved
from its default pin position (pins 1–2), the move allows the module firmware (including BIOS) in the PFR-
controlled PCH capsule file to be downgraded to a lower Security Version Number (SVN). This jumper is used
when there is a need for the module to power on using BIOS revision with lower SVN.
Caution: Downgrading to an older version of BIOS may result in the loss of functionality and security features
that are present in a higher SVN.
Caution: When downgrading to an older version of BIOS, modules may end up with a firmware stack
combination that is not supported, and therefore could experience unpredictable behavior.
Note: Latest system update packages are included in the SUP posted to Intel's download center. See
Table
1.
To use the SVN Bypass jumper, perform the following steps:
1. Power down the Intel® D50TNP Module.
2. Remove the module from the chassis
