J-RTC - RTC Reset
The jumper J-RTC may be used to reset certain register bits of the battery backed RTC core within
the PCH RM590E. This can be necessary under rare conditions (e.g. battery undervoltage), if the
CPU fails to enter the UEFI/BIOS POST after power on. Note that installing of jumper J-RTC will
neither set UEFI/BIOS Setup to EKF Factory Defaults nor resets the time and date register values of
the RTC (Real Time Clock). To reset the RTC core the board must be removed from the system rack.
Short-circuit the pins of J-RTC for about 1 sec. Thereafter reinstall the board to the system and
switch on the power. The pin header J-RTC is not stuffed on the SC9-TOCCATA by default.
NOTE: It is important to execute the RTC reset while the board has no power.
