Power supply 2 (available on some models)
The hot-swap redundant power supplies help you avoid significant interruption to the operation of the
system when a power supply fails. You can purchase a power supply option from Lenovo and install the
power supply to provide power redundancy without turning off the server.
On each power supply, there are three status LEDs near the power cord connector. For information about the
LEDs, see "Rear view LEDs" on page 20.
6 NMI button
Press this button to force a nonmaskable interrupt (NMI) to the processor. By this way, you can make the
operating system halt (such as Windows Blue Screen of Death) and take a memory dump. You might have to
use a pen or the end of a straightened paper clip to press the button.

USB 3.0 connectors (2)
Used to attach a device that requires a USB 2.0 or 3.0 connection, such as a USB keyboard, USB mouse, or
USB storage device.
