Front view

This section contains information about the controls, LEDs, and connectors on the front of the server.

Note
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 AGroup B
    USB port 4 (with display support)USB port 3 (with display support)
    HDMI 2.0 connectorsXCC 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 Fan error LED of Ethernet adapter expansion kit (Amber)​

When a fan error LED on the Ethernet adapter expansion kit is lit, it indicates that the corresponding system fan is operating slowly or has failed.

2 USB 3.2 Gen2 (10 Gbps) Type-A connectors (USB port 1 and port 2)​

Connect a USB device, such as a mouse, keyboard, or other devices, to either of these connectors.

3 Locked button​

After pressing this button, the server will be in System Lockdown Mode for security and the security LED of the server will start blinking. See Front LEDs to identify the security LED status. The lockdown button will not respond if the button is pressed after the system has already entered BIOS Setup menu or OS.

4 System buttons and LEDs​

The buttons and LEDs provide controls and system status. The following buttons and LEDs are in this area:
  • UART status LED (white)
  • System Error LED (yellow)
  • Security LED (green)
  • Power button with power status LED (green)
  • UID button with LED (blue)
See Front LEDs for more information.

5 UART switch button​

Press this button to switch the UART output between XCC log (Lenovo service technicians only) or CPU log. After powering on the server, the output is CPU log by default. See Front LEDs to determine the status of the UART output.

6 USB 3.2 Gen 2 (10 Gbps) Type-C connector with display support (USB port 4)​

Connect a USB device, such as a mouse, keyboard, monitor, or other devices, to this connector. This connector supports display.
Note

  • The maximum video resolution is 4K at 60 Hz.

  • The connector supports up to 15 watts of power (5V/3A).

7 USB 3.2 Gen 2 (10 Gbps) Type-C connector with display support (USB port 3)​

Connect a USB device, such as a mouse, keyboard, monitor, or other devices, to this connector. Configure the UEFI setting through this port as a priority.

Note

  • When configuring UEFI settings or powering on the system remotely through XCC, make sure to connect the monitor to USB Type-C connectors with display support (USB port 3).

  • The maximum video resolution is 1920 x 1200 at 60 Hz.

  • The connector can support up to 15 watts of power (5V/3A).

8 RJ-45 RS-232 serial console connector for OS/BIOS or XCC​

Connect an external RJ-45 serial COMM console cable to this RS-232 serial console with RJ-45 connector.

9 HDMI 2.0 connectors​

Connect a HDMI-compatible device to either of these connectors.
Note
The maximum video resolution is 4K at 60 Hz.

Expansion filler​

Install the expansion filler when the node is not installed with a expansion kit. See Install the expansion filler for more information.


Front I/O fillers​

Install the I/O fillers when the connectors are not used. The connectors could be dust-covered without proper protection of the fillers.
