Memory Voltage Select

JP2 is used to specify the voltage lev- el for the onboard memory (SDRAM). The default setting is on pins 1-2, which lets the BIOS automatically determine the correct setting. See the table on the right for jumper settings.

Watch Dog Enable/Disable

JWD controls the Watch Dog func- tion. Watch Dog is a system monitor that can reboot the system when a software application is “hung up”. Pins 1-2 will cause WD to reset the system if an application is hung up. Pins 2-3 will generate a non-maskable inter- rupt signal for the application that is hung up. See the table on the right for jumper settings. Watch Dog must also be enabled in BIOS.

Note: When enabled, the user needs to write their own application software to disable the Watch Dog Timer.

I2C Enable/Disable

JI2C1 and JI2C2 are used to enable or disable I2C bus on the serverboard. See the table on the right for jumper settings. Both jumpers must be set the same for the setting to to function cor- rectly (one jumper enables the clock and the other enables the data). The default setting is disabled.
