4.11.1 Reset Switch
The Reset switch on the motherboard sends a reset order to the CPUs, resetting the
main system, but not the service processor. The button for this switch is one of the 3
hidden (recessed) buttons on the back of the motherboard located between the NET
MGT and NET0 connectors and closest to NET0. It 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 motherboardlocated between the NET MGT and NET0 connectors. 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 CPUs,
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
Sun Integrated
Lights Out Manager 2.0 User's Guide .
