4 Power supply bays 1-4 (bottom to top)
Install power supply units to these bays, connect them to power cords. Make sure the power cords are connected properly. See Technical specifications for the power supplies supported by this system.
For information about the LEDs, see Power supply LEDs.
5 11 OCP slots
6 XCC system management port (1 GB RJ-45)
The server has a 1 GB 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.
7 USB 3.2 Gen 1 (5Gbps) connector with USB 2.0 XCC system management (depending on the configuration)
The connector can function as a regular USB 3.2 Gen 1 connector to the host OS; it can be used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.
When there are no USB connectors at the front, this connector can function as a USB 2.0 Lenovo XClarity Controller management port.
8 USB 3.2 Gen 1 (5 Gbps) connectors
The connector can be used to attach a USB-compatible device, such as a USB keyboard, USB mouse, or USB storage device.
9 VGA connector
Connect a monitor to this connector.
10 Serial port (optional)
Connect a 9-pin serial device to this connector. The serial port is shared with XCC. XCC can take control of the shared serial port to redirect serial traffic, using Serial over LAN (SOL).
