38 IntelĀ® Server Board S3420GP User Guide
When performing the standard Integrated BMC firmware update procedure, the update 
utility places the Integrated BMC into an update mode, allowing the firmware to load 
safely onto the flash device. In the unlikely event the Integrated BMC firmware update 
process fails (due to the Integrated BMC not being in the proper update state), the server 
board provides an Integrated BMC Force Update jumper, which forces the Integrated 
BMC into the proper update state. You should complete the following procedure in the 
event the standard Integrated BMC firmware update process fails. 
Note: Normal Integrated BMC functionality is disabled with the Force Integrated BMC Update 
jumper set to the enabled position. The server should never be run with the Integrated 
BMC Force Update jumper set in this position. This jumper setting should only be used 
when the standard firmware update process fails. This jumper should remain in the 
default / disabled position when the server is running normally.
1. Power down and remove the AC power cord.
2. Open the server chassis. For instructions, refer to your server chassis 
documentation.
3. Move the jumper from the default operating position (covering pins 1 and 2) to the 
enabled position (covering pins 2 and 3).
4. Close the server chassis.
5. Reconnect the AC cord and power up the server.
6. Perform the Integrated BMC firmware update procedure as documented in the 
README.TXT file included in the given Integrated BMC firmware update 
package. After successful completion of the firmware update process, the firmware 
update utility may generate an error stating the Integrated BMC is still in update 
mode.
7. Power down and remove the AC power cord.
8. Open the server chassis.
9. Move jumper from the enabled position (covering pins 2 and 3) to the disabled 
position (covering pins 1 and 2).
10. Close the server chassis.
11. Reconnect the AC cord and power up the server.
