5 OCP slot 2
The OCP slot supports OCP module with two or four extra Ethernet connectors for network connections.
One of the Ethernet ports on the OCP module can also function as a management port with shared
management capacity. If the shared management port fails, traffic can automatically switch over to another
port on the OCP module.

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).
7 NMI button
Press this button to force a nonmaskable interrupt to the processor. You might have to use a pen or the end
of a straightened paper clip to press the button. You can also use it to force a blue-screen memory dump.
Use this button only when you are directed to do so by Lenovo Support.
8 / 10 / 11 USB 3.1 Gen 1 (5 Gbps) connectors

XCC system management port (1 GB RJ-45)
12
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.
