Non-Maskable Interrupt Switch (NMI button/SW3)
When an operating system crashes, system administrators can initiate a non-maskable
interrupt (NMI) event by pressing a dump switch. The NMI event enables a hung system to
once again become responsive.
The NMI switch is used
only
in the event of a service emergency that requires a complete
data dump in preparation for recovering the system from a catastrophic failure.
Front Panel Buttons and LEDs
Front panel status LEDs allow constant monitoring of basic system functions while the server
is operating. Figure 4-5 and Table 4-6 provide the LED locations and functions.
