Operating the Server System Modules via Front Panel Controls

007-4566-001
The front panel of the base compute module, the system expansion compute module,
and the MPX module provides the following control features, as shown in Figure 1-33:
Note: If your server system includes other modules such as the TP900 and the PCI
expansion module, see the operating instructions provided for those modules.
• 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 server is still
operating.
• Failure LED. This LED illuminates red to indicate that a failure has occurred
and the server is down.
• Power button. Press this button to power on the server. Alternatively, you can
power on the server system at a system console.
• 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.
