Front components overview​

Integrated Diagnostics Panel​

The diagnostics panel is integrated in front I/O assembly on some models. For information about the controls and status LEDs on the diagnostics panel, see Integrated diagnostics panel.

External diagnostics port​

The connector is for connecting an external diagnostics handset. For more about its functions, see External diagnostics handset.

Front operator panel​

The assembly comes with an integrated diagnostics panel that can be used to quickly obtain system status, firmware levels, network information, and health information about the system. For more about the panel functions, see Front operator panel.

Hot-swap drives and drive bays​

The drive bays on the front and rear of your server are designed for hot-swap drives. The number of the installed drives in your server varies by model. When you install drives, follow the order of the drive bay numbers.

The EMI integrity and cooling of the server are protected by having all drive bays occupied. Vacant drive bays must be occupied by drive fillers.

Pull-out information tab​

The Lenovo XClarity Controller network access label is attached on the pull-out information tab. The default Lenovo XClarity Controller hostname and the IPv6 Link Local Address (LLA) are provided on the tab.

For more information, see Set the network connection for the Lenovo XClarity Controller.

Rack latches​

If your server is installed in a rack, you can use the rack latches to help you slide the server out of the rack. You also can use the rack latches and screws to secure the server in the rack so that the server cannot slide out, especially in vibration-prone areas. For more information, refer to the Rack Installation Guide that comes with your rail kit.

USB 3.2 Gen1 (5 Gbps) connectors​

The USB 3.2 Gen1 (5 Gbps) connectors can be used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.

VGA connector​

The VGA connectors on the front and rear of the server can be used to attach a high-performance monitor, a direct-drive monitor, or other devices that use a VGA connector.

XClarity Controller USB connector​

The XClarity Controller USB connector can function as a regular USB 2.0 connector to the host OS. In addition, it can also be used to connect the server to an android or iOS device, where you can then install and launch the Lenovo XClarity Mobile app to manage the system using XClarity Controller.

For details about using the Lenovo XClarity Mobile app, refer to Lenovo XClarity Administrator Mobile app online documentation.

OCP 3.0 module​

Figure 1. OCP module (two connectors)

Figure 2. OCP module (four connectors)

• The OCP module provides two or four extra Ethernet connectors for network connections.

• By default, any Ethernet connector on the OCP module can also function as a management connector using the shared management capacity.
