An error has been detected on the server. Causes might include one or more of the following errors:

  • The temperature of the server reached the non-critical temperature threshold.

  • The voltage of the server reached the non-critical voltage threshold.

  • A fan has been detected to be running at low speed.

  • The power supply has a critical error.

  • The power supply is not connected to the power.

Check system logs or internal error LEDs to identify the failed part.

5 System ID button/LED (blue)​

Use this system ID button and the blue system ID LED to visually locate the server. Each time you press the system ID button, the state of the system ID LED changes. The LED can be changed to on, blinking, or off. You can also use the Lenovo XClarity Controller or a remote management program to change the state of the system ID LED to assist in visually locating the server among other servers.

6 USB 2.0 connector with Lenovo XClarity Controller management​

Connect a USB 2.0 device, such as a mouse, keyboard, or other devices, to this connector.
Note
This is the only USB port that supports USB automation update of the firmware and RoT security module.

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.

Select Network in BMC Configuration to view or modify settings.

Four types of settings are available:

  • Host only mode

    In this mode, the USB port is always solely connected to the server.

  • BMC only mode

    In this mode, the USB port is always solely connected to Lenovo XClarity Controller.

  • Shared mode: owned by BMC

    In this mode, connection to the USB port is shared by the server and Lenovo XClarity Controller, while the port is switched to Lenovo XClarity Controller.

  • Shared mode: owned by host

    In this mode, connection to the USB port is shared by the server and Lenovo XClarity Controller, while the port is switched to the server.

7 USB 3.2 Gen 1 (5 Gbps) connector​

The USB 3.2 Gen 1 (5 Gbps) connector can be used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.

8 3.5-inch drive bay​

Depending on the model, the server might come with a 3.5-inch drive installed in this drive bay. See Install a simple-swap drive (bay 2) for more details.

9 Optical drive bay​

Depending on the model, the server might come with an optical drive installed in the optical drive bay. See Optical drive and drive cage replacement for more details.
