L1 Front Panel Controls
The L1 front panel of the Altix 450 IRU provides the following control features, as shown in
Figure 1-22:
•
Status LEDs. The front panel has the following LEDs:
•
Power button LED. This LED illuminates green when the internal components are on.
•
Service-required LED. This LED illuminates yellow to indicate that an item is not
functioning properly (for example, a fan is off), but the IRU is operating.
•
Failure LED. This LED illuminates red to indicate that a failure has occurred and the
module is down.
•
Power button. Normally you power on the system from the system console. Alternatively,
you can press this button to power on the module.
•
Reset button. Actuate 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. Actuate the NMI (non-maskable interrupt) button to reset the internal
processor(s) and ASICs, and write register data and memory to the /var/adm/crash file.
Use a paperclip or other small object to access the “pin-hole” actuators on the front panel.
