Rear view
This section contains information about the LEDs and connectors on the rear of the server.
- If the system is installed with the operating system Ubuntu 24.04.2, make sure to follow the following rules before configuring the system in multi-monitor environment:
The display ports on the server can be separated into two types of groups. To avoid causing any problem to the display function of the connector, it is only allowed to connect the monitors to the connectors in either group A or group B.
Group A Group B USB port 4 (with display support) USB port 3 (with display support) HDMI 2.0 connectors XCC system management port (10/100/1000 Mbps RJ-45) Do not support accessing the remote console functionality only. Before accessing the remote console functionality, connecting the monitors to this port and the connectors in group A at the same time, the display function can still work normally.
Make sure the display mode is set as “Mirror Display”.
Depending on the model, your server might look slightly different from the illustration.

1 2 USB Type-C power connectors
Connection to Lenovo XClarity Controller is primarily intended for users with a mobile device running the Lenovo XClarity Controller mobile application. When a mobile device is connected to this USB port, an Ethernet over USB connection is established between the mobile application running on the device and the Lenovo XClarity Controller.
BMC only mode
In this mode, the USB port is always solely connected to Lenovo XClarity Controller.
3 PCIe slot (expansion kit)
Install a PCIe adapter into this slot. See Install the PCIe adapter for more information.
4 Fan control board connector
Connect a fan control board power cable to this connector for the server installed in the enclosure. See Internal cable routing of SE100 Enclosure for more information.
5 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.
6 1GbE RJ-45 connectors
Connect an Ethernet cable to either of these connectors for LAN connection. See XCC system management port (10/100/1000 Mbps RJ-45) and LAN port LEDs for more information.
7 USB 3.2 Gen2 (10 Gbps) Type-A connectors
Connect a USB device, such as a mouse, keyboard, or other devices, to either of these connectors.
8 Power input LEDs (green/yellow)
| LED | Status | Description |
| Power input LED | On (green) | The server is connected to the power adapter and working normally. |
| On (yellow) | The server is connected to the power adapter but can not be powered on since the power capability is unable to support the system requirement. | |
| Off | The power adapter is disconnected or a power problem occurs. |
