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.
PCIe slots
The PCIe slots are on the rear of the server and your server supports up to three PCIe slots on riser 1 and 2
assemblies.
Power supply units
The hot-swap redundant power supply helps 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 "Power supply LEDs" on page 296.
USB 3.1 Gen 1 (5Gbps) connectors
The USB 3.1 Gen 1 (5Gbps) connectors are direct connect interfaces (DCIs) for debugging, which can be
used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.
VGA connector
The VGA connectors on the front and rear of the server can be used to attach a high-performance monitor, a
direct-drive monitor, or other devices that use a VGA connector.
XClarity Controller network connector
The XClarity Controller network connector can be used to attach an Ethernet cable to manage the baseboard
management controller (BMC).
