4.3.1 NMI Button

The Non-Maskable Interrupt (NMI) button can be accessed through a pin hole with a thin object (e.g., the

end of a paperclip). Pressing this button results in a Non-Maskable Interrupt to the CPU, which halts all CPU

operations.

There are 2 System ID buttons—one on the front panel of all servers and one on the back panel of rack-dense

and rackable tower servers. When the System ID buttons are pressed, the System Status/ID LED in the front

and in the back blink, identifying the particular server in a rack full of servers. This button remains

functional during non-operational (that is, standby and shutdown) modes.

The power button controls the system's power, turning the unit on and off. All PowerEdge servers have the

power LED light-pipe integrated in the power button. The LED is a green standard Power icon.
