The front panel of the compute module has the following items:
• L1 controller display. A liquid crystal display (LCD) displays status and error
messages that the L1 controller generates.

See the SGI L1 and L2 Controller Software User’s Guide (007-3938-00 x ) for more
information on the L1 controller.
• Power button with LED . Press this button to power on the internal components.
Alternatively, you can power on the internal components at a system console. The
LED illuminates green when the internal components are on.
• Reset button . Press this button to reset the internal processors and ASICs. The reset
will cause a memory loss. (To perform a reset without losing memory, see the NMI
button information that follows.)
• NMI button . Press the NMI (non-maskable interrupt) button to reset the internal
processors and ASICs without losing memory. Register data and memory are stored
in a
/var/adm/crash
file.
• Service-required LED . This LED illuminates yellow to indicate that an item has
failed or is not operating properly, but the compute module is still operating.
•
Failure LED
. This LED illuminates red to indicate that a failure has occurred and
that the compute module is down.
