Fixed power supply model

The rear of the server provides access to several components, including the power supplies, PCIe adapters, serial port, and Ethernet port.

Note
Depending on the configuration, your server might be slightly different from the image.

1 PCIe slot 1

Install PCIe adapters into this slot.

2 PCIe slot 2

Install PCIe adapters into this slot.

3 Power supply bay

Install a fixed power supply unit to this bay, connect them to power cords. Make sure the power cords are connected properly. See Install the fixed power supply unit.

4 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.

5 USB 3.2 Gen 1 (5 Gbps) connectors

The USB 3.2 Gen 1 (5 Gbps) 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.

6 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.

7 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 Settings Network Interface Port : Shared. Then, click Shared NIC on and select Share OnLom Port:01.

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

The server has a 1 GB 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.

9 VGA connector

Connect a monitor to this connector.

10 Serial port

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.
