4 Drive status LED (yellow)​

These LEDs indicate the following status:
  • The LED is lit: the drive has failed.
  • The LED is flashing slowly (once per second): the drive is being rebuilt.

5 Pull-out information tab​

This tab contains network information such as MAC address and XCC network access label.

6/7 USB connectors​

Connect a USB device, such as a mouse, keyboard, or other devices, to either of these connectors. Following are detailed descriptions of each connector:

  • USB 1: USB 2.0 with Lenovo XClarity Controller management.

    Connection to XClarity Controller is primarily intended for users with a mobile device running the 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 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 XClarity Controller.

    • Shared mode: owned by BMC

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

    • Shared mode: owned by host

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

  • USB 2: USB 3.1.

8 Power button/LED (green)​

Press this button to turn the server on and off manually. The states of the power LED are as follows:
  • Off: No power supply unit is properly installed or connected, or the LED itself has failed.
  • Flashing rapidly (four times per second): The server is turned off and not ready to be turned on yet. The power button is disabled. This will last approximately five to ten seconds after power supply units are properly installed and connected.
  • Flashing slowly (once per second): The server is power off but ready to be turned on. Press the power button to turn on the server.
  • Lit: The server is turned on.

9 Network activity LED (green)​

When this LED is lit, it indicates that the server is transmitting to or receiving signals from the Ethernet LAN.

10 Identification button/LED (blue)​

Use this blue LED to visually locate the server among other servers. This LED is also used as a presence detection button. You can use Lenovo XClarity Administrator to light this LED remotely.

11 System error LED (yellow)​

When this yellow LED is lit, it indicates that a system error has occurred. This LED can be controlled by the XCC. Information provided from the LCD display of the LCD diagnostics panel could also help isolate an error.

13 Rack release latches​

Press on the latch on both sides to disengage the server from the rack and slide it out.

  • LCD diagnostics panel
    The LCD diagnostics panel is attached to the front of the server, while it allows quick access to system information such as errors, system status, firmware, network, and health information.
