1 PCIe riser 1 (PCIe slot 15-16)

Install PCIe adapters to the PCIe riser. These PCIe slots support the following configuration:
  • PCIe x16 75W, FH/HL

2 PCIe riser 2 (PCIe slot 20-21)

Install PCIe adapters to the PCIe riser. These PCIe slots support the following configuration:
  • PCIe x16 75W, FH/HL

3 Power supply units

Install power supply units to these bays, connect them to power cords. Make sure the power cords are connected properly. Following are the power supplies supported by this system:

  • 1800-watt Platinum, input voltage 230 Vac
  • 1800-watt Titanium, input voltage 230 Vac
  • 2400-watt Platinum, input voltage 230 Vac
  • 2600-watt Titanium, input voltage 230 Vac
Each hot-swap power supply has three status LEDs:

Power supply LEDs
LEDDescription
1 Input status
The input status LED can be in one of the following states:
  • Off: The power supply is disconnected from the AC power source
  • Green: The power supply is connected to the AC power source.
2 Output status
The output status LED can be in one of the following states:
  • Off: The server is powered off, or the power supply is not working properly. If the server is powered on but the output status LED is off, replace the power supply.
  • Green: The server is on and the power supply is working normally.
3 Fault LED
  • Off: The power supply is working normally
  • Amber: The power supply has failed. To resolve the issue, replace the power supply.

4 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.

5 USB 3.2 Gen 1 (5 Gbps) connectors

There are three USB 3.2 Gen 1 (5 Gbps) connectors on the rear of the server. Connect a USB device, such as a mouse, keyboard, or other devices, to either of these connectors.

6 VGA connector

Connect a monitor to this connector.

7 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.

See the following for more information:
Note
In addition to the standard 1000 Mbps data transfer rate, the XCC system management port also supports 10 Mbps, 100 Mbps speeds.

8 OCP module (slot 27)

The system may support a 2-port or a 4-port OCP module for network connections. Port numbering are shown in the illustrations below.
