SC CPU Reset Button
I
When the RESET button on the front panel of the SC CPU board is pressed, a
Power-on-reset (POR) is generated to the SC CPU board and a peripheral
component interconnect (PCI) reset is generated to the PCI devices on the SC
main board. This results in a general clearing of the SC CPU board to a power on
state, and a reset of the PCI bus on the SC main board.
Using the RESET button will reboot the operating system on the SC if the
appropriate OpenBoot PROM (OBP) environment variables have been set.
* The SC 6U/3U spare slot is
not supported at this time.
