1 Rear fan​

Install the rear fan in this space.

2 Padlock loop​

This loop is available for installing a padlock. See Server locks for more information.

3 Kensington lock​

This loop is available for installing a Kensington lock. See Server locks for more information.

4 Power cord connector​

Connect the power cord to this component.

5/6/7 PCIe slots​

There are three PCIe slots on the system board to install appropriate PCIe adapters. For information about the PCIe slots, see Specifications.

8 NMI button​

Press this button to force a nonmaskable interrupt 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.

9 USB 3.2 Gen 1 (5 Gbps) connectors​

There are four USB 3.2 Gen 1 (5 Gbps) connectors on the rear of the server. Connect a USB device, such as a mouse, keyboard, or other devices, to either of these connectors.

10 Ethernet connector 2​

Attach an Ethernet cable for LAN. Each Ethernet connector has two status LEDs to help you identify the Ethernet connectivity and activity.

11 Ethernet connector 1 (shared with XCC network port)​

Attach an Ethernet cable for LAN. Each Ethernet connector has two status LEDs to help you identify the Ethernet connectivity and activity. If the LOM adapter is not installed, Ethernet connector 1 can be set as Lenovo XClarity Controller Network connector.

To set Ethernet connector 1 as Lenovo XClarity Controller Network connector, start Setup Utility and select BMC Settings > Network Settings > Network Interface Port : Shared. Then, click Shared NIC on and select Share OnLom Port:01.

12 XCC system management port (10/100/1000 Mbps RJ-45)​

The server has a 10/100/1000 Mbps RJ-45 connector dedicated to Lenovo XClarity Controller (XCC) functions. Through the system management port, you can access the Lenovo XClarity Controller directly by connecting your laptop to the management port using an Ethernet cable. Make sure that you modify the IP settings on the laptop so that it is on the same network as the server default settings. A dedicated management network provides additional security by physically separating the management network traffic from the production network.

See the following for more information:

13 VGA connector​

Connect a monitor to this connector.
Note
The maximum video resolution is 1920 x 1200 at 60 Hz.

14 Serial connector​

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

Note
If the Serial over LAN (SOL) or Emergency Management Services (EMS) feature is enabled, the serial port will be hidden on Linux and Microsoft Windows. Therefore, it is required to disable SOL and EMS to use the serial port on operating systems for serial devices.
To enable the serial port module on Linux or Microsoft Windows, see Tip for enabling the serial port on supported operating system.
