Watch Dog
JWD1 controls the Watch Dog function. Watch Dog is a monitor that can reboot the system
when a software application hangs. Jumping pins 1-2 will cause Watch Dog to reset the
system if an application hangs. Jumping pins 2-3 will generate a non-maskable interrupt
signal for the application that hangs. Watch Dog must also be enabled in BIOS. The default
setting is Reset.
Note: When Watch Dog is enabled, the user needs to write their own application
software to disable it.
Manufacturing Mode Select
Close JPME2 to bypass SPI flash security and force the system to use the Manufacturing
Mode, which will allow you to flash the system firmware from a host server to modify system
settings. See the table below for jumper settings.
VRM_I2C Jumper
Set this jumper (JVRM_SEL1) to Normal (Default) to allow BMC to access VRM controllers.
Set this jumper to short pins 2-3 to have VRM code updated by PCH. See the table below
for jumper settings.
10Gb LAN1/2 Enable/Disable
