Front Power Switch; Using The Reset Button - Silicon Graphics Origin200 Owner's Manual

Front Panel Functions: Status LED, Power, Reset, NMI

Front Power Switch

The front power switch causes the module system controller to either turn on or turn off
power to the system. The master power switch at the rear of the system must be on in
order for the front power switch to work.
When you press the front power switch to turn the system on, the module system
controller signals the power supply to shut off power to the drive bays, PCI backplane,
and main system board and CPU daughter card.
The module system controller itself remains active until the master power switch is
turned off.

Using the Reset Button

Use the reset button if the system is completely unresponsive (you cannot type
commands to it) and you want to reboot the server without shutting it off. The reset
button skips the automatic power-on diagnostic tests.
To reset the system, press the reset button. (See Figure 4-1). After you press the reset
button, the system status LED on the front panel turns red briefly, then green, and the
system reboots.
