Figure A-4 illustrates the front controls and indicators of the SGI Origin 300 base module.
• L1 controller display is a liquid crystal display (LCD) that displays status and error
messages that the L1 controller generates.
• Power button with LED enables you to manually power on and power off the
Origin 300 base module. Alternatively, you can power on and off the base module at
a system console. The LED illuminates green when the internal components are on.
• Reset button resets the internal processors, ASICs, and memory.
Note: This reset causes memory loss. (Refer to the non-maskable interrupt [NMI] to
perform a reset without losing memory.)
• Non-maskable interrupt (NMI) button resets the internal processors and ASICs
without losing memory. Register data and memory are stored in a
/var/adm/crash file.
• Service required LED illuminates yellow to indicate that an item has failed or is not
operating properly, but the base module is still operating.
• Failure LED illuminates red to indicate that a failure has occurred and the base
module is down.
• Drive LEDs illuminate green to indicate drive activity.
