properly configure the server or data loss could occur. 
  
 
NMI functionality 
An NMI crash dump enables administrators to create crash dump files when a system is hung and not 
responding to traditional debug mechanisms. 
Crash dump log analysis is an essential part of diagnosing reliability problems, such as hangs in 
operating systems, device drivers, and applications. Many crashes freeze a system, and the only 
available action for administrators is to cycle the system power. Resetting the system erases any 
information that could support problem analysis, but the NMI feature preserves that information by 
performing a memory dump before a hard reset. 
To force the OS to invoke the NMI handler and generate a crash dump log, the administrator can do any 
of the following: 
 
Short the NMI jumper pins 
 
Press the NMI switch 
 
Use the iLO Virtual NMI feature
