chassis. This includes shutting down the operating system (if possible) and
removing power from the compute node.
If an operating system is running, you might have to press the button for
approximately 4 seconds to initiate the shutdown.
Attention: Pressing the button for 4 seconds forces the operating system
to shut down immediately. Data loss is possible.
NMI button
The NMI button is recessed and can be accessed only by using a small
pointed device. Pressing this button causes a nonmaskable interrupt for
debugging purposes.
KVM connector
Connect the console breakout cable to this connector (see "Console
breakout cable" for more information).
USB connector
Connect a USB device to this connector.

Console breakout cable

Use this information for details about the console breakout cable.
Use the console breakout cable to connect external I/O devices to the compute
node. The console breakout cable connects through the KVM connector (see
"Compute node controls, connectors, and LEDs" on page 10). The console breakout
cable has connectors for a display device (video), two USB connectors for a USB
keyboard and mouse, and a serial interface connector.
The following illustration identifies the connectors and components on the console
breakout cable.
