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.
