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 OCP slot 2
6 Serial port
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).
8 / 10 / 11 USB 3.2 Gen 1 (5 Gbps) connectors
The USB 3.2 Gen 1 (5 Gbps) connectors are direct connect interfaces (DCIs) for debugging, which 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.
12 XCC system management port (10/100/1000 Mbps RJ-45) (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.
13 OCP slot 1
- The system may support a 2-port or a 4-port OCP module for network connections. Port numbering are shown in the illustrations below.Figure 4. Port numbering — 2-port OCP moduleFigure 5. Port numbering — 4-port OCP 3.0 module
The system may support a Management NIC adapter. Install the management NIC adapter into the OCP slot in place of the OCP module to function as a redundant XCC system management port (10/100/1000 Mbps RJ-45).
