4.11.1 Reset Switch
The Reset switch (SW2 on the motherboard) sends a reset order to the processors,
resetting the main system, but not the service processor. The button for this switch
can be pushed by sticking a paper clip or similar object through the hole provided on
the rear of the chassis.
4.11.2 NMI Dump Switch
The NMI button is the center button of the row of 3 hidden (recessed) buttons on the
back of the motherboard. The button for this switch can be pushed by sticking a
paper clip or similar object through the hole provided on the rear of the chassis.
The Non-Maskable Interrupt (NMI) Dump switch sends an NMI order to the
processors, which is used by Field Service for debugging activities at the request of
operating system engineers. NMI can also be asserted by ILOM. Refer to the
