On each power supply, there are three status LEDs near the power cord connector. For more details, see Power supply LEDs.

3 External Diagnostics Handset connector​

Connect the External Diagnostics Handset here. For more details, see External Diagnostics Handset.

4 XClarity Controller network connector​

Used to attach an Ethernet cable to manage the system using XClarity Controller. For more details, see XCC system management port (10/100/1000 Mbps RJ-45) LEDs.

5 USB 3.1 Gen 1 connectors​

Used to attach a device that requires a USB 2.0 or 3.2 Gen 1 connection, such as a keyboard, a mouse, or a USB flash drive.

6 NMI button​

Press this button to force a non-maskable interrupt (NMI) to the processor. You might have to use a pen or the end of a straightened paper clip to press the button. You can also use it to force a blue-screen memory dump. Use this button only when you are directed to do so by Lenovo Support.

7 PCIe slots 1-4 (top to bottom)​

Install PCIe adapters into these slots.

8 10GbE connector​

This connector is used to attach a 10Gb Ethernet cable. Each 10GbE connector has two status LEDs to help identify the Ethernet connectivity and activity. For more information, see Rear system LEDs.

9 Serial-port-module slot​

Connect a 9-pin serial device to this connector. The serial port is shared with the XCC. The XCC can take control of the shared serial port to redirect serial traffic, using Serial over LAN (SOL).

10 VGA connector​

Used to attach a VGA-compatible video device, such as a VGA monitor.

11 PCIe slots 5-9 (top to bottom)​

Install PCIe adapters into these slots.
